The concept of information as we use it in everyday English in the sense knowledge communicated plays a central role in today's society. The concept became particularly predominant since end of World War II with the widespread use of computer networks.
The rise of information science in the middle fifties is a testimony of this. For a science like information science (IS) it is of course important how its fundamental terms are defined, and in IS as in other fields the problem of how to define information is often raised. This review is an attempt to overview the present status of the information concept in IS with a view also to interdisciplinary trends. In scientific discourses theoretical concepts are not true or false elements or pictures of some part of reality, but are constructions designed to do a job the best possible way. Different conceptions of fundamental terms like information are thus more or less fruitful depending on what theories (and in the end what practical actions) they are expected to support. In Chapter 1, we discuss the problems of defining terms in the light of the philosophy of science. The discussions about the information concept in other disciplines are also very important for Information Science because many theories and approaches in Information Science have their origins in other disciplines.
This is surveyed in Chapter 3. The epistemological concept of information has lead also to a new perspective of non-human information processes particularly in physics and biology. And vice versa: processes of selection and interpretation may be considered when related to psychic and social phenomena with regard to objective parameters, leaving aside the semantic dimension or, more precisely, considering objective or situational parameters of interpretation. This can be illustrated also in physical terms with regard to release mechanisms as we suggest at the end of Chapter 3. Our overview of the concept of information in the natural sciences as well as in the humanities and social sciences does not aim at exploring different theories in depth.
In most cases we can only refer to fragments of theories that the user may interpret within her own background or follow the hints of the bibliography. Readers mostly interested in information science may get more satisfied with Chapter 4 where we bring a more detailed explanation of diverse views and theories of information within our field, supplementing the ARIST article by Cornelius (2001). We show that the introduction of the concept of information about 1950 to what was formerly special librarianship and documentation in itself has had serious consequences for the kind of knowledge and theories developed in our field. The important question is not only what meaning we give to the term in Information Science, but also how it relates to other basic terms such as documents, texts and knowledge.
The concept of information as we use it in everyday English, in the sense knowledge communicated, plays a central role in contemporary society. The development and widespread use of computer networks since the end of World War II, and the emergence of information science as a discipline in the 1950s, are evidence of this focus. Although knowledge and its communication are basic phenomena of every human society, it is the rise of information technology and its global impacts that characterize ours as as an information society. It is commonplace to consider information as a basic condition for economic development together with capital, labor, and raw material; but what makes information especially significant at present is its digital nature.
The impact of information technology on the natural and social sciences has made this everyday notion a highly controversial concept. Claude Shannon's (1948) 'A Mathematical Theory of Communication' is a landmark work, referring to the common use of information with its semantic and pragmatic dimensions, while at the same redefining the concept within an engineering framework. The fact that the concept of knowledge communication has been designated with the word information seems, prima facie, a linguistic happenstance.
For a science like information science (IS) it is of course important how fundamental terms are defined; and in IS, as in other fields, the question of how to define information is often raised. This chapter is an attempt to review the status of the concept of information in IS, with reference also to interdisciplinary trends.
In scientific discourse, theoretical concepts are not true or false elements or glimpses of some element of reality; rather, they are constructions designed to do a job the best possible way. Different conceptions of fundamental terms like information are thus more or less fruitful, depending on the theories (and in the end, the practical actions) they are expected to support. In the opening section, we discuss the problem of defining terms from the perspective of the philosophy of science. The history of a word provides us with anecdotes that are tangential to the concept itself.
But in our case, the use of the word information points to a specific perspective from which the concept of knowledge communication has been defined. This perspective includes such characteristics as novelty and relevance; i.e., it refers to the process of knowledge transformation, and particularly to selection and interpretation within a specific context. This discussion leads to the questions of why and when this meaning was designated with the word information. We explore this history, and we believe that our results may help readers better understand the complexity of the concept with regard to its scientific definitions. Discussions about the concept of information in other disciplines are very important for IS because many theories and approaches in IS have their origins elsewhere (see the section 'Information as an Interdisciplinary concept' in this chapter). The epistemological concept of information brings into play nonhuman information processes, particularly in physics and biology. And vice versa: the psychic and sociological processes of selection and interpretation may be considered using objective parameters, leaving aside the semantic dimension, or more precisely, by considering objective or situational parameters of interpretation.
This concept can be illustrated also in physical terms with regard to release mechanisms, as we suggest. Our overview of the concept of information in the natural sciences as well as in the humanities and social sciences cannot hope to be comprehensive. In most cases, we can only refer to fragments of theories. However, the reader may wish to follow the leads provided in the bibliography. Readers interested primarily in information science may derive most benefit from the section on 'Information in Information Science,' in which we offer a detailed explanation of diverse views and theories of information within our field; supplementing the recent ARIST chapter by Cornelius (2002).
We show that the introduction of the concept of information circa 1950 to the domain of special librarianship and documentation has in itself had serious consequences for the types of knowledge and theories developed in our field. The important question is not only what meaning we give the term in IS, but also how it relates to other terms basic terms, such as documents, texts, and knowledge. Starting with an objectivist view from the world of information theory and cybernetics, information science has turned more to the phenomena of relevance and interpretation as basic aspects of the concept of information. This change is in no way a turn to a subjectivist theory, but an appraisal of different perspectives that may determine in a particular context what is being considered as informative, be it a 'thing' (Buckland, 1991b) or a document.
Different concepts of information within information science reflect tensions between a subjective and an objective approach. The concept of interpretation or selection may be considered to be the bridge between these two poles. It is important, to consider the different professions involved with the interpretation and selection of knowledge. The most important thing in IS (as in information policy) is to consider information as a constitutive force in society and, thus, recognize the teleological nature of information systems and services (Braman, 1989).
It is well known that definitions are not true or false, but more or less fruitful. In a way, people are free to define terms as they like, but in reality their definitions may encounter problems. In children’s play, a chair can be defined as a table and vice versa.
This works as long as the children remember and obey their own decisions and do not apply their own conventions with outsiders. However, when somebody defines a term in such an idiosyncratic way, that definition will be neglected and will not contribute to understanding, communication, or the advance of practice.
Knowing how different people apply the terms they use is helpful. Wittgenstein’s (1958a) famous use theory of meaning emphasizes this aspect, defining terms by finding out how people actually use them (see Blair's chapter in this volume).
This aspect also applies to the term information. Dictionaries such as The Oxford English Dictionary (1989), provide valuable insights about the etymology of a word and how different authors have used it throughout the centuries (see Appendix). This etymology should be supplemented by more detailed descriptions of how the word has been used in different disciplines. The actual use of terms may differ from their more formal definitions. The ordinary use of a term like information may carry other meanings than formal definitions, implying that conflicting theoretical views may arise between the explicit scientific definitions of ordinary use. Because of this tendency, we must not only compare different formal definitions, but also consider the meaning of a word like information as it is used in relation to, for example, information seeking, information systems, and information services.
Studies of how a term has been used cannot, however, help us to decide how we should define it. When we use language and terms, we perform some kind of act, with the intention of accomplishing something.
The different meanings of the terms we use are more or less efficient tools to help us accomplish what we want to accomplish. In this way, according to pragmatic philosophers such as Charles Sanders Peirce (1905), the meaning of a term is determined by not just the past, but also the future. We also cite Braman (1989), pointing out how important it is for information policy to define information adequately, thus applying this pragmatic principle of definition in practical policy. Observation statements must be expressed in the language of some theory. Consequently, it is argued, the statements, and the concepts figuring in them, will be as precise and informative as the theory in whose language they are formed is precise and informative. For instance, I think it will be agreed that the Newtonian concept of mass has a more precise meaning than the concept of democracy, say.
It is plausible to suggest that the reason for the relative precise meaning of the former stems from the fact that the concept plays a specific, well-defined role in a precise, closely knit theory, Newtonian mechanics. By contrast, the social theories in which the concept “democracy” occurs are vague and multifarious. If this suggested close connection between precision of meaning of a term or statement and the role played by that term or statement in a theory is valid, then the need for coherently structured theories would seem to follow directly from it. Chalmers also considers alternative ways to defining scientific terms, by, for example, lexical or ostensive definitions. The main problem with lexical definitions is that concepts can be defined only in terms of other concepts, the meanings of which are given. If the meanings of these latter concepts are themselves established by definition, it is clear that an infinite regress will result, unless the meanings of some concepts are known by other means. A dictionary is useless unless we already know the meanings of many words.
Newton could not define mass or force in terms of previously available concepts. It was necessary for him to transcend the limits of the old conceptual framework by developing a new one. The main problem with ostensive definitions is that they are difficult to sustain, even in the case of an elementary notion like apple. Defining something like mass in mechanics, electrical field in electromagnetism or information, subject or topicality in information science (IS) is even more challenging.
The dependence of the meaning of concepts on the structure of the theory in which they occur — and the dependence of the precision and degree of coherence of the latter — is thus made plausible by noting the limitations of some of the alternative ways in which a concept might be thought to acquire meaning. Chalmers also points out that the typical history of a concept, whether it be chemical element, atom, the unconscious, and so forth, typically involves the emergence of the concept as a vague idea, followed by its gradual clarification as the theory in which it plays a part takes a more precise and coherent form. He argues that Galileo was in the process of making a major contribution to the building of a new mechanics that was to prove capable of supporting detailed experimentation at a later stage. It is hardly surprising that — contrary to popular myth — his efforts involved thought experiments, analogies, and illustrative metaphors rather than detailed experimentation. This situation is understandable if it is accepted that experimentation can only be carried out if one has a theory capable of yielding predictions in the form of precise observations.
In fact, we are not obliged to accept the word information as a professional term at all. It might be that this word is most useful when left without any formal definition, like e.g., the word discussion, or the word difficulty, or the word literature. It might be that the word information is useful in particular when we try to rise our professional status in relation to other professions; it sounds smart and imposing and gives an air of technicality. I find no moral objections to this sort of use of words; language is certainly not only for informative uses (“informative” here refers to the so-called intellectual or factual meaning of a text or an utterance). However, we must realize that the status-rising effect of a word may depend precisely on its being used in other fields as well, preferably in fields having a high status, like engineering and nowadays sociology. The uses in such other fields actually makes it impossible at the same time to keep this word as a formally defined professional term in our field without some risk of confusion; the words force, energy and effect—used both generally and in physics as formally defined terms—illustrate this situation.
The word information—and combinations like information retrieval, information center—have definitely contributed to rise the public opinion of library and documentation work, which is generally held to be a little dull, dusty and distant from what is actually going on in society. Maybe it would be wise to leave the word information there, were it not for the fact—already mentioned—that several attempts have been made to define information as a formal term relative to documentation and information work, and even attempts to define information as some measurable quantity, corresponding to questions of the type: How much information was retrieved by the search? Many kinds of definitions exist (Yagisawa, 1999). The tendency to use and define terms in order to impress other people has been called persuasive definition. The definition provided by Brookes (1977) K(S) + δ I –>K(S + δ S) seems to us to serve only such a persuasive function. If we agree with Spang-Hanssen that definitions are legitimate ways to boost the status of a profession and research field, we must face the fact that such use can cause internal confusion and lack of self-respect in the discipline.
Schrader, among others, has demonstrated this outcome. He studied about 700 definitions of information science and its antecedents from 1900 to 1981 and found that. [ T] he literature of information science is characterized by conceptual chaos. This conceptual chaos issues from a variety of problems in the definitional literature of information science: uncritical citing of previous definitions; conflating of study and practice; obsessive claims to scientific status; a narrow view of technology; disregard for literature without the science or technology label; inappropriate analogies; circular definition; and, the multiplicity of vague, contradictory, and sometimes bizarre notions of the nature of the term 'information' (Schrader, 1983, p.99). As we can see, the cost of applying persuasive definitions in IS has been extremely high; this approach should no longer be accepted by journals and authorities in the field.
We have to ask more seriously: What role—if any—should the concept of information play in IS? In order to answer this question, one must clarify the role and nature of scientific theories in IS.
We suggest that focusing on the concept of information may have misdirected our field, and that a closer relation to concepts such as signs, texts, and knowledge may provide more satisfactory conceptual frameworks for the kind of problems that IS is trying to answer. When we use the term information in IS, we should always keep in mind that information is what is informative for a given person. What is informative is depends on the interpretative needs and skills of the individual (although these are often shared with members of a discourse community).
The word information has Latin roots ( informatio). Before we explore this thread we should examine its entry in The Oxford English Dictionary (1989, see Appendix).
We shall consider two basic contexts in which information is used; namely, the act of molding the mind and the act of communicating knowledge. These two activities are, obviously, intimately related.
But when and how do information and molding belong together? Based on studies by Seiffert (1968) and Schnelle (1976), Capurro (1978) explores the Greek origins of the Latin word informatio as well as its subsequent development. This historico-critical background makes possible a better understanding of the higher-level concepts of information in the Hellenistic period as well as in the Middle Ages and in modern times. Peters' (1988) view is highly supportive of these analyses.
The Thesaurus Linguae Latinae (See footnote 2) (1900) gives detailed references to the uses of informatio and informo in Latin since Vergil (70-19 B.C.) until the eighth century. There are two basic contexts, namely a tangible ( corporaliter) and an intangible ( incorporaliter) one. The prefix in may have the meaning of negation as in informis or informitas, but in our case it strengthens the act of giving a form to something, as in Vergil's verses on Vulcan and the Cyclops hammering out ( informatum) lightning bolts for Zeus ( Aen.
8, 426) or a huge shield for Aeneas ( Aen. Early references to the use of informo are in a biological context, for instance by Varro (116-27 B.C.) who describes how the foetus is being 'informed' ( informatur) by head and backbone ( Frg. The intangible or spiritual context concerns moral and pedagogical uses since the second century A.D. That reveal not only the influence of Christianity — Tertullian (ca.
160-220 A.D.) calls Moses populi informator; that is, people's educator or molder — but in several cases also an explicit reference to Greek philosophy, particularly to Plato (427-348/7 B.C.) and Aristotle (384-322 B.C.). Several Greek words that were translated with informatio or informo such as hypotyposis ( which means model, especially in a moral context) and prolepsis (representation), but most higher-level uses are mostly explicitly related to eidos, idea, typos and morphe; that is, to key concepts of Greek ontology and epistemology (Capurro 1978). This relationship is clearly the case with prominent thinkers such as, for instance, Cicero (106-43 B.C.) and Augustine (354-430 A.D.). Nevertheless, these higher-level concepts have their roots in the low-level use of these words, particularly in the primitive context of pottery as well as in the Greek experience of limitation and shining-forth of what we perceive sensually ( phainonemon).
Cicero explicitly translates in De natura deorum Epicure's (341-270 B.C.) concept of prolepsis — i.e. The representations of the gods or of things impressed in our souls before any experience (a priori, as Kant would say) as informatio rei ( nat.deor. At the same time he uses this word in a rhetorical context — for instance in De oratore (2, 358) as well as in Orator, where he explicitly points to Plato's ideas ( orat. 10) — in order to describe the active and a posteriori action of the mind depicting something unknown or helping memory, as part of the ars memoriae, to better remember a past situation through the pictorial representation of a sentence ( sententiae informatio).
Several references are to the use of informo in a biological as well as in a pedagogical and moral context. A particularly interesting one can be found in his speech Pro Archia. In Augustine, we have the influence of Greek ontology and epistemology on the one hand, and of Christian tradition on the other. In De trinitate, Augustine calls the process of visual perception informatio sensus ( trin. 11,2,3) and he uses the famous Platonic ( Theaet. 191d) and Aristotelian ( De an.
424 a 17) metaphor of the impression ( imprimitur) of a ring seal into wax ( trin. According to Augustine, the images or representations of the perceived objects are stored in memory. These images do not inform, following the Platonic view, the soul ( mens) or the rational intellect ( intelligentia rationalis), but only reflection ( cogitatio); that is, the faculty dealing with internal representations ( informatio cogitationis) ( trin. Augustine uses informatio also in a pedagogical context: Christ is God's form ( forma dei). His deeds instruct and educate us ( ad eruditionem informationemque nostram) ( epist. In De civitate dei, he describes the process of illumination of the heavenly community ( informatio civitatis sanctae) ( civ. >Following Thomas Aquinas' interpretation of the Aristotelian concepts of form ( eidos or morphe) and matter ( hyle), both principles cause the unity of an individual being ( informatio materiae) in the sense listed by the OED: 'the action of 'informing' with some active or essential quality' (OED II, 7).
The Aristotelian theory was called hylomorphism. From a theological point of view it is important for Thomas to distinguish between the biological process giving life on the basis of something that already exists ( per modum informationis) and the act of creation out of nothing ( per modum creationis) ( In de causis 18/94). In other words, there is an ontological difference — i.e. A difference concerning the meaning of being, not just a difference between beings — between informatio and creatio. Because of the unity of the human body with the soul as substantial form ( forma substantialis) Thomas underlines, in contrast to Augustine, the unity of the knowledge process conceived as a double movement of abstracting (' abstractio') the forms ( forma, species) — the Aristotelian eidos or morphe — of things and of going back to the things in a process of sensory-bounded intellectual re-cognition (' conversio ad phantasmata'). Thomas' termini technici for these processes are informatio sensus and informatio intellectus possibilis ( Summa theol. I, 14.2.co/4).
He underlines the role of the active intellect ( intellectus agens) in the (re-)cognition process. Finally, he conceives information processes, similarly to Augustine, in a large pedagogical and moral context, where informatio means the forming of virtues ( informatio virtutum) as well as of moral life as a whole ( informatio morum) ( Summa theol. III, 110.4.co/15). 'The action of 'informing' with some active or essential quality' had, according to the Oxford English Dictionary 'a quite restrictive use' not only in English, but also in other modern European languages, and references on 'formation or molding of the mind or character, training, instruction, teaching' date from the 14th century. Probably the most intriguing question from the point of view of the history of ideas concerns the ontological use of informatio — both in the lower-level sense of 'molding matter' as well as in the higher-level sense used by Scholastics as informatio materiae — which became obsolete not only in modern languages that, like English, inherited the Latin word and slightly transformed it into information, retaining the epistemological meaning, but also, for instance, in German where the word Information was actually used in the sense of education and communication since the 15th century.
Informatio was literally translated — first in a mystical context as in-Bildunge or in-Formunge; later on in a general pedagogical sense, such as used by Christoph Martin Wieland (1733-1813) — with Bildung, a term heavily charged with higher-level meaning (Capurro 1978, p. A plausible explanation for the loss of the ontological higher-level sense is the decline of Scholastic philosophy caused by the rise of modern empirical science. As Peters (1988, p. The 'doctrine of ideas,' developed initially by Descartes, was central to early modern philosophy, both rationalist and empiricist. Abandoning the 'direct perception' of the scholastics — the immediate communion of Intellect and Nature — Descartes interposed 'ideas' between the two.
An 'idea' was something present to the mind, an image, copy, or representation, with a problematic relation to real things in the world. For empiricists (like Locke), the stream of ideas was the raw material from which genuine knowledge could be built; for rationalists (like Descartes), it was a veil of illusion, to be pierced by logic and reason. Criticizes the logicians of his day for receiving 'as conclusive the immediate informations of the sense.' Instead, those 'informations' must be subjected, according to Bacon, to a sure plan that will sort the true form the false. Though Bacon's usage may not appear irreconcilable with our own, the inverted pluralization should tip us off that he does not completely share our prejudices (we should say 'the information of the senses'). In fact, this locution exemplifies a perfectly hylomorphic notion of the workings of the senses: they are a kind of matter (wax being a favorite empiricist instance) on which objects of the world may leave their shapes or stamps. What is interesting here is that the site of information is being shifted from the world at large to the human mind and senses.
This shift requires no break with scholastic notions of mind or nature. Information was readily deployed in empiricist philosophy (though it played a less important role than other words such as impression or idea) because it seemed to describe the mechanics of sensation: objects in the world in-form the senses. But sensation is entirely different from 'form' — the one is sensual, the other intellectual; the one is subjective, the other objective.
My sensation of things is fleeting, elusive, and idiosynchratic [ sic]. For Hume, especially, sensory experience is a swirl of impressions cut off from any sure link to the real world. In any case, the empiricist problematic was how the mind is informed by sensations of the world. At first informed meant shaped by; later it came to mean received reports from.
As its site of action drifted from cosmos to consciousness, the term's sense shifted from unities (Aristotle's forms) to units (of sensation). Information came less and less to refer to internal ordering or formation, since empiricism allowed for no preexisting intellectual forms outside of sensation itself. Instead, information came to refer to the fragmentary, fluctuating, haphazard stuff of sense. Information, like the early modern worldview more generally, shifted from a divinely ordered cosmos to a system governed by the motion of corpuscles. Under the tutelage of empiricism, information gradually moved from structure to stuff, from form to substance, from intellectual order to sensory impulses. Later developments on etymology are partly covered by the next section. Here we will conclude that the modern uses of information show a transition period in which the medieval ontological concept of 'molding matter' is not just abandoned but reshaped under empirical and epistemological premises.
It has been extremely interesting to observe how the concept of information is closely connected to views of knowledge. This conclusion is important when we later analyze the concept of information in information science, because it indicates a severly neglected connection between theories of information and theories of knowledge. My skepticism about a definitive analysis of information acknowledges the infamous versatility of information. The notion of information has been taken to characterize a measure of physical organization (or decrease in entropy), a pattern of communication between source and receiver, a form of control and feedback, the probability of a message being transmitted over a communication channel, the content of a cognitive state, the meaning of a linguistic form, or the reduction of an uncertainty.
These concepts of information are defined in various theories such as physics, thermodynamics, communication theory, cybernetics, statistical information theory, psychology, inductive logic, and so on. There seems to be no unique idea of information upon which these various concepts converge and hence no proprietary theory of information. (See footnote 3). In their seminal book The Study of Information: Interdisciplinary Messages, Machlup and Mansfield (1983) collected key views on the interdisciplinary controversy in computer science, artificial intelligence, library and information science, linguistics, psychology, and physics, as well as in the social sciences. Machlup (1983, p.
660) himself disagrees with the use of the concept of information in the context of signal transmission, the basic senses of information in his view al referring 'to telling something or to the something that is being told. Information is addressed to human minds and is received by human minds.' All other senses, including its use with regard to nonhuman organisms as well to society as a whole, are, according to Machlup, metaphoric and, as in the case of cybernetics, anthropomorphic. The confusion started with the abstraction of meaning in information theory (Shannon & Weaver, 1972). Machlup (1983, p.
660) found that human sciences like psychology, economics, decision theory, and linguistics had adopted the basic human-related meaning, asserting it with some restrictions. The requirement of truth or correctness should exclude false or incorrect messages; the requirement of value or usefulness should exclude messages not helpful in decisions and actions; the requirement of novelty should exclude repeated or redundant messages; the requirement of surprise should exclude messages that the recipient expected; the requirement of uncertainty-reduction should exclude messages that leave the recipient's state of uncertainty unchanged or increased; and so forth. No exhaustive enumeration of persuasive or dictatorial restrictions is here intended. More than 10 years later, Kornwachs and Jacoby (1996) edited Information. New Questions to a Multidisciplinary Concept. This volume displays a general tendency toward what we might call the naturalization of information.
In his contribution 'Can Information Be Naturalized?,' Zoglauer responds in the negative with regard to semantic and pragmatic information, which is different from syntactic information; that is, from any kind of mind-dependent semiotic units as well as functional information whose interpreter can be a Turing machine and/or any kind of living organism processing neural and genetic information. Also in this volume Capurro (1996) defines information as an anthropological category concerning the phenomenon of human messages, whose vertical and horizontal structures are related to the Greek concept of message ( angelia) and as well as to philosophic discourse ( logos). The controversy surrounding the naturalization of information goes back to the work of physicists and engineers such as L.
Boltzmann, J. Wiener, and particularly to R.V.L. Hartley (1928, p. 536) who in his article 'Transmission of Information,' argued that, because electrical transmission systems have to do with machines and not with human beings, 'it is desirable therefore to eliminate the psychological factors involved and to establish a measure of information in terms of purely physical quantities.' The word information, in this theory, is used in a special sense that must not be confused with its ordinary usage. In particular, information must not be confused with meaning. In fact, two messages, one of which is heavily loaded with meaning and the other of which is pure nonsense, can be exactly equivalent, from the present viewpoint, as regards information.
It is this, undoubtedly, that Shannon means when he says, 'the semantic aspects of communication are irrelevant to the engineering aspects.' But this does not mean that the engineering aspects are necessarily irrelevant to the semantic aspects. (Shannon & Weaver, 1949, p. Information is prima facie something that flows between a sender and a receiver. But Shannon's definition of information is quantitative concerning possible selections from a repertoire of physical symbols.
It is, in fact, as Underwood (2001) remarks, a theory of signal or message, not of information transmission. Shannon's model of communication includes six elements: a source, an encoder, a message, a channel, a decoder, and a receiver (Shannon 1948; 1972, 34, Fig. 1; See; see also, and 's critique of this model) Strictly speaking no information could be communicated between a sender and a receiver, because this theory is not concerned with the communication of a meaningful message, but with the reproduction of a selection process. Shannon correlates information — that is, the number of possible choices in order to create a message — and uncertainty. The greater the freedom of choice, the greater the uncertainty; that is, the information. This concept of information seems, as Weaver remarks, 'disappointing and bizarre — disappointing because it has nothing to do with meaning, and bizarre because it deals not with a single message but rather with the statistical character of a whole ensemble of messages, bizarre also because in these statistical terms the two words information and uncertainty find themselves to be partners' (Shannon & Weaver 1972, p.
Fleissner and Hofkirchner call this problem 'Capurro's trilemma,' which is indeed an Aristotelian one (Capurro 1995; Capurro, Fleissner, & Hofkirchner 1999; Fleissner & Hofkirchner 1995). The view of evolution as self-organization offers, according to Fleissner and Hofkirchner, a paradigm for dealing with this problem. In the process of evolution, different kinds of low structures generate higher-level structures, starting with physical systems through biological systems to social systems. Evolution is an autopoietic process in which these systems select possible ways of reaction, and forms are transformed.
It is a nondeterministic process that is not merely ruled by the classic concept of causality ( actio est reactio) but by the principle: causa non aequat effectum, actio non est reactio, or, 'equal causes do not have equal effects, every action does not have an equal reaction' (Fleissner & Hofkirchner, 1999, p. This second type of self-organized causality is based on informational relations. This information concept is related to its Latin origins as information; meaning a dynamic process of formation and not just the meaning of a message (Fleissner & Hofkirchner, 1995). A unified theory of information should give an account of the dynamic process of evolution that embraces the whole of reality (Hofkirchner 1999).
Laszlo (1999, p. 6) asks for 'invariant patterns appearing in diverse transformation' during the evolutionary process. Brier (1999) conceives of cybersemiotics as an ontological and epistemological framework for a universal information science. The evolutionary dissolution of the trilemma has, in our opinion, a metaphysical rather than a scientific status insofar as it presupposes a view of the whole of reality that is not possible for a finite observer. The majority of biologists, especially molecular biologists, appear to accept that biological information is indeed a natural entity, which expresses itself in the specific structures of biological macromolecules.
However, this attitude has recently been the target of strong criticism from the constructivistic philosophers of science (Janich 1992). Their main attack has been directed against the application of the concept of information in non-human areas that are governed entirely by natural laws. Nevertheless, we note that Shannon retains a basic aspect of the modern concept of information in the sense of knowledge communication, namely selection. When dealing with the meaning of a message we discuss interpretation; that is, the selection between semantic and pragmatic possibilities. To interpret a message means, in other words, to introduce the receiver's perspective — her or his beliefs and desires; to make her or him an active partner in the information process. We would like to suggest a difference between motivational (or anthropological) and casual (or natural) theories of information. Shannon develops a perspective, as we shall show, on causal theories of information with different kinds of 'family resemblance' (Wittgenstein 1958a).
One important resemblance between the two kinds of theories is the role of selection in each. Even in the extreme case in which any interpretation is supposedly excluded — as in the engineering perspective of the conduit metaphor — we can still recognize a process of selection. In other words, we state a resemblance between interpreting meaning and selecting signals. The concept of information makes this resemblance possible. Bar-Hillel pointed to the 'semantic traps' of Shannon's terminology, particularly with regard to the analogies between the psychological and the engineering fields. Bar-Hillel and Carnap (1953) developed a semantic theory of information in which they distinguish between information and amount of information within a linguistic framework.
Dretske's (1981, p. 63-64) theory of semantic information is based on the distinction between information and meaning. Information does not require an interpretive process, although it is a necessary condition for acquiring knowledge. He states three conditions that a definition of information must satisfy, namely.
On one hand, information is not an absolute concept, because we can acquire varying degrees of information about a source. On the other hand, however, 'the information that s is F does not come in degrees. It is an all or nothing affair.' (Dretske, 1981, p. 108) According to Dretske (1981, pp. 80-81), information is always relative to 'a receiver's background knowledge' ( k); it is 'something that is required for knowledge.'
It is indeed a 'harmless fiction' to think about a number of possibilities existing at the source 'independently of what anyone happened to know.' There is no false information but there is meaning without truth (Dretske, 1981, pp. Indeed, 'information is what is capable of yielding knowledge, and since knowledge requires truth, information requires it also' (Dretske, 1981, p.
The flow of information is based on the following Xerox principle: 'If A carries the information that B, and B carries the information that C, then A carries the information that C' (Dretske, 1981, p. 57) Dretske's information concept is different from meaning, but basically related to cognitive systems. The relation between knowledge and information is a recursive but not a circular one. In order to learn that s is F a person should know about s, without knowing that s is F.
On the other hand, the information that s is F 'causes K's belief that s is F.' 'Knowledge is information-produced belief' (Dretske, 1981, pp. 91-92) Thus, in the case of 'genuine cognitive systems,' as distinct from 'mere processors of information,' knowledge is specified with regard to information, meaning, and belief; or, in other words, with regard to interpretation during the learning process. Computers have, at least so far, no capability of using information.
It means nothing to them. They can only manipulate symbols (Dretske, 1986). Dretske's definition of information does not initially include k (that is, the receiver's background knowledge). This cognitivistic limitation seems illegitimate if we consider other kinds of receivers or, more precisely, other kinds of situations. Becoming aware of this contradiction, Barwise and Perry (1983) developed situation theory and situation semantics (STASS). This theory is based on the idea of regularities between types of situations, which allow an information flow to take place (Barwise & Seligman, 1997).
Linguistic regularities, as considered by Dretske, are a special case of this flow. Information is a key concept in sociology, political science, and the economics of the so-called information society. According to Webster (1995, 1996), definitions of information society can be analyzed with regard to five criteria: technological, economic, occupational, spatial, and cultural (Webster, 1995, p. The technological definition is concerned with the applications of information technologies in society. The economic definition goes back to the pioneering work of Machlup (1962), Boulding (1966), Arrow (1979), and Porat (1977). The occupational definition is at the heart of Porat's and Bell's (1973) theories. The spatial definition concerns information networks and the emergence of a 'network marketplace' (Castells, 1989).
The cultural definition is related to the influence of media in society. Classic theoreticians of the information society are, according to Webster: Bell, Giddens, Schiller, Habermas, Baudrillard, Vattimo, Poster, Lyotard, and Castells.
According to Bougnoux (1993, 1995) the concepts of information and communication are inversely related: Communication is concerned with forecasting and redundancy; information with the new and the unforeseen. There is no pure information or 'information- in-itself' (that is, information is always related to some kind of redundancy or 'noise'). To inform (others or oneself) means to select and to evaluate. This is particularly relevant in the field of journalism and mass media, but, of course, also in information science.
The action of bringing a message and the message itself were designated in Greek by the terms angellein and angelia (Capurro, 1978). The modern concept of information as knowledge communication is not related just to a secular view of messages and messengers but includes also a modern view of empirical knowledge shared by a (scientific) community. Postmodernity opens this concept to all kinds of messages, particularly within the perspective of a digital environment.
We may call a science of knowledge (better: message) communication information science or angeletics (Capurro, 2000). Flusser (1996) has developed a 'communicology' in which 'discursive media' are concerned with the distribution of information whereas 'dialogical media' deal with the creation of new information. Flusser fears that mass media may swallow up dialogical media into a hierarchical model. He did not foresee the Internet as a communication structure in which both media would merge beyond a central or panoptic power. It is, of course, an open question how far this is, or will be, the case.
Symantec System Recovery 2011 Disk Iso Reader there. Krippendorff (1994) has explored different information and communication metaphors such as the one of message transmission, the container metaphor, the metaphor of sharing common views, the argument metaphor, the canal metaphor, and the control metaphor. These metaphors are originated within different cultural environments. The phenomena they address are intimately related to the metaphors themselves. We must learn to use them creatively; that is, to see their limits and to learn how to apply them accurately in different theoretical and practical situations. Braman (1989) provides an important discussion of approaches to defining information for policy makers.
Four major views are identified: (1) information as a resource, (2) information as a commodity, (3) information as a perception of patterns, and (4) information as a constitutive force in society. The relative benefits and problems with each of these four conceptions are discussed. The article points out that the selection of one definition or another has important consequences, and also that the tendency to neglect this problem results in conflicts rather than cooperation.
Defining information is thus also a political decision. The information age is also called 'the age of access' (Rifkin, 2000). Information production, distribution, and access is at the heart of the new economy. The terminological shift from information society to knowledge society signals that the content, and not information technology, is the main challenge for economy as well as for society in general.
From the perspective of knowledge management, information is used to designate isolated pieces of meaningful data that, when integrated within a context, constitute knowledge (Gundry 2001; Probst, Raub, & Romhard, 1999). This semantic concept of information, located between data and knowledge is not consistent with the view that equates information (management) with information technology. According to Nonaka and Takeuchi (1995) — who follow Polanyi's (1966) distinction between tacit and explicit knowledge — only explicit knowledge (information) can be managed. Correctly speaking, knowledge cannot be managed, only enabled (von Krogh, Ichijo, & Nonaka 2000).
For Cornella (2000), companies are information. Castells (1996-1998) gives a comprehensive and critical analysis of the information age, including its social, economic, and cultural dimensions. For Hobart and Schiffman (2000), information is not a phenomenon that appears with modern technology but rather the product of the complex interactions between technology and culture. They distinguish between classical, modern, and contemporary information ages, the meaning of information being unique ito each age. Brown and Duguid (2000) question 'the myth of information' and information technologies that would be able to shape social organization by themselves. For it is not shared information but shared interpretation that binds people together.
Borgmann's (1999, p. 57) critical appraisal of the nature of information is a plea for a new cultural and ethical balance between what he calls technological, natural, and cultural information: 'Natural information pivots on natural signs — clouds, smoke, tracks. Cultural information centers on conventional signs — letters and texts, lines and graphs, notes and scores.' Borgmann (1999, pp. 218-219) sees technological information is the product of developments that began a century ago. We started this presentation of interdisciplinary theories by asking whether a common core can be found in the concept of information. According to Karpatschof (2000, pp.
131-132): Information The quality of a certain signal in relation to a certain release mechanism. The signal being a l ow energy phenomenon fulfilling some release specifications. The signal is thus the indirect cause, and the process of the release mechanism the direct cause of the resulting high-energy reaction. The release mechanism itself is, of course, an emergent entity, when it is seen from a cosmological position.
This is the precise agenda, for biogony and biogenesis to furnish theories with an analysis of this emergence. We can thus more precisely define: Release Mechanisms Systems having at their disposal a store of potential energy, the system being ”designed” to let this energy out in a specific way, whenever trigged by a signal fulfilling the specifications of the release mechanism. It is now clear why there has been this tendency to consider information to be an obscure category that is in addition to the classical categories of physics. Information is indeed a new category, but it cannot be placed, eclectically, beside the prior physical categories. Information is a category, not beside, but indeed above the classical categories of physics. Therefore, information is neither directly reducible to these classical categories, nor is it a radically different category of another nature than mass and energy. Information is, in fact, the causal result of existing physical components and processes.
Moreover, it is an emergent result of such physical entities. This is revealed in the systemic definition of information.
It is a relational concept that includes the source, the signal, the release mechanism and the reaction as its relatants. One might ask where I place the category of information in my system of ontology. Should it be placed in the object field of cosmology, just as mass, energy and causality? Or, should it be placed in the object field of biology? My answer to this question will be the latter position. (all emphasis in original). In our opinion Karpatschof's explanation identifies a key perspective of the concept of information that most interdisciplinary discussions can agree upon.
It seems to be a reductionistic and indeed mechanical perspective, antithetical to a humanistic understanding. However, this is not the case.
Karpatschof does not explain psychological or sociological phenomena by physical or biological principles. He does not consider information as a thing or as something objective. He forces us to look at the many different kinds of mechanisms at different levels in evolution and culture that have evolved to discriminate certain kinds of signals. In other words, he forces us to shift the perspective from information as an object to the subjective mechanisms that account for discrimination, interpretation, or selection. What distinguishes different theories of information is, thus, not so much the concept of information itself. It is, to a much higher degree, the nature of the 'release mechanism' (or “information processing mechanisms”), the selectors or interpreters. To ask about the nature of this mechanism means, for instance, to ask about the nature of living organisms, the nature of human beings, human language, society, and technology.
Because there are many kinds of release mechanisms developed both in biology, in the human mind, in cultures, and in technologies, different sciences tend to work with different concepts and theoretical frames of reference. Information can and should thus be studied within a network of different disciplines, not just by 'information science' (Capurro 2001). No wonder, then, that the mechanisms of information — and information itself — had been so difficult to tackle. As we have seen, the word information has a much richer history than have the fields of inquiry known as library science, documentation, and information science, which are largely products of the 20th century.
Tracing the influence of this term and the very complex net of disciplines connected with it is indeed difficult. Machlup & Mansfield (1983, p. 22) suggested that “in the broad sense information science is a rather shapeless assemblage of chunks picked from a variety of disciplines that happen to talk about information in one of its many meanings”.
In this chapter only a few important points will be illuminated. Information desk appeared as an alternate to reference desk by 1891. Information bureau was in use by 1909 to denote an office where reference service was provided; in 1924 the Association of Special Libraries and Information Bureaux (Aslib) was founded in Britain. In the Aslib Proceedings for 1932, information work was introduced to describe reference assistance. Use of information as an equivalent of reference began to give way, under the influence of developments in computing, to more sophisticated usage. (Shapiro, 1995, p.
The term information was also used in 1915 by the American special librarian, Ethel Johnson, who noted, “before everything else, it [the special library] is an information bureau. The main function of the general library is to make books available. The function of the special library is to make information available” (quoted from Williams, 1998, p.
According to Williams (1998), special librarians were the first documentalists in the U.S.; and, according to Rayward (1998), documentalists can be seen as the first information scientists. We are thus able to trace one line of development from special librarianship via documentation to information science in both the U.K. The line of development from Paul Otlet (1934) and Suzanne Briet (1951) is discussed by Day (2001) in critical fashion. Library science as taught in schools of librarianship has always had public libraries as a major focus simply because public libraries have constituted an important marked for professionally trained librarians. This situation has influenced both the focus of the field and its underlying assumptions, preferences, and “paradigms” (for example, in the predilection for universal classification systems and the relative neglect of domain specific knowledge).
Special librarianship and documentation (and later information science), on the other hand, were much more concerned with research libraries, databases, and with activities connected to the seeking and dissemination of scientific literature — and also with the application of information technologies. Documentation/information science was originally based more on specific subject knowledge (chemistry has played an especially important role in information science), whereas special librarianship relied more on education and training in schools of librarianship.
According to Williams (1998, p. 177) special librarians in the U.S. Lost ground to documentalists and information scientists because they lacked the specific subject knowledge to handle complex information (for example, in chemical indexing and retrieval). These changes, particularly when confronted with the insistence of the documentalists that a new profession different from librarianship, even special librarianship, needed to be developed, had the effect of making them [the special librarians] more general library oriented and less special library oriented. The overall effect on special librarianship and SLA [Special Libraries Association] is a decline in their domination of new developments in information management. As will be shown in the next section, one of the major reasons special librarians had lost this dominance was because they emphasized general education in librarianship to the neglect of the scientific fields they had to serve.
They were now librarians first and foremost, and only knowable about their subject areas second, if at all. However, since about 1975, information science has been foregrounded in schools of library and information science. This may be due in part to an increasing interest in being associated with such important fields as computer-based information retrieval and other areas of information science. Although schools of library science are major contributors in the field, as reflected in their contributions to the leading journals in IS; they have also faced challenges, particularly in the U.S.
This situation may be connected to what they teach, including the old problem concerning the lack of specific subject knowledge. It may be, however, that the neglect of subject knowledge reflects a privileging of research into users rather than information, and, by implication, a tendency towards psychologism, subjective idealism, and methodological individualism (See footnote 4). The question is how well we have succeeded in developing information science as a healthy field of inquiry. The term information retrieval (IR) is possibly one of the most important terms in the field known as information science. A critical question is, thus, why, and in what sense, IR uses the term information. IR can be seen both as a field of study and as one among several research traditions concerned with information storage and retrieval (See footnote 5).
Although the field is much older, the tradition goes back to the early 1960s and the Cranfield experiments, which introduced measures of recall and precision. Those experiments rang among the most famous in IS and continue today in the TREC experiments (Text REtrieval Conference). This tradition has always been closely connected to document/text retrieval, as stated by van Rijsbergen (1979, p. Information retrieval is a wide, often loosely-defined term but in these pages I shall be concerned only with automatic information retrieval systems. Automatic as opposed to manual and information as opposed to data or fact. Unfortunately the word information can be very misleading. In the context of information retrieval (IR), information, in the technical meaning given in Shannon's theory of communication, is not readily measured (Shannon and Weaver).
In fact, in many cases one can adequately describe the kind of retrieval by simply substituting 'document' for 'information'. Nevertheless, 'information retrieval' has become accepted as a description of the kind of work published by Cleverdon, Salton, Sparck Jones, Lancaster and others.
A perfectly straightforward definition along these lines is given by Lancaster: 'Information retrieval is the term conventionally, though somewhat inaccurately, applied to the type of activity discussed in this volume. An information retrieval system does not inform (i.e. Change the knowledge of) the user on the subject of his inquiry. It merely informs on the existence (or non-existence) and whereabouts of documents relating to his request.' This specifically excludes Question-Answering systems as typified by Winograd and those described by Minsky. It also excludes data retrieval systems such as used by, say, the stock exchange for on-line quotations.'
(Notes to references omitted). In 1996, van Rijsbergen and Lalmas (p. 386), however, declared that the situation had changed and that the purpose of an information retrieval system was to provide information about a request. Although some researchers have fantasized about eliminating the concept of document/text and simply storing or retrieving the facts or 'information' contained therein, it is our opinion that IR usually means document retrieval and not fact retrieval (See footnote 6). We shall return to the difference between documents and facts later, but here we want to show why information (and not, for example, document, text, or literature) was chosen as a central term in this core area.
Ellis (1996, pp. 187-188) describes 'an anomaly' in IS. From an information science point of view, research on IR systems offers only a theoretical cul-de-sac.
It leads nowhere. The anomaly I have noted is this: the information-handling processes of the computers used for IR systems, their storage capacities, their input and internal information transmissions, are measured in terms of Shannon theory measures—in bits, megabits per second, and so forth. On the other hand, in the theories of information retrieval effectiveness information is measured in what I call physical measures—that is, the documents (or document surrogates) are counted as relevant or non-relevant and simple ratios of these numbers are used. The subsequent probabilistic calculations are made as though the documents were physical things (as, of course, they are in part), yet the whole enterprise is called information retrieval theory. So why, I ask, are logarithmic measures of information used in the theory of the machine and linear or physical measures of information in IR theory? If information retrieval theory were called document retrieval theory, the anomaly would disappear. And document retrieval theory would fall into place as a component of library science, which is similarly concerned with documents.
But that is too simple an idea. Those who work on IR theory explicitly claim to be working on information, not documentation.
I therefore abandon the simple explanation of a misuse of terminology. I have to assume that IR theorists mean what they say—that they are contributing to information science.
But are they?’ (emphasis in original). Ellis and Brookes should not refer to the opinion of researchers in their attempts to solve this problem. Only arguments count. In our view, it is not too simple an idea to claim that information retrieval theory is in reality document retrieval theory and thus closely associated with library science. It is not difficult to disprove Brookes's statement that information retrieval does not deal with documents. A short examination of the literature demonstrates this, and even if the Cranfield experiments spoke about 'information retrieval,' their modern counterpart, the TREC experiments, speak about 'text retrieval.' 'Text retrieval' and 'document retrieval' are often used as synonyms for IR.
If one read Brookes’s statement in the light of the relationship between the early documentalists and information scientists, it becomes clear that information scientists wanted to forge a distinctive identity to be both more information technology-oriented and more subjected-knowledge oriented. One reason for information scientists to prefer not to be linked to library science might be that important technological improvements were carried out not by people associated with librarianship, but by those affiliated with computer science. This preference is most probably the reason they claimed to work with “information, not documentation.” Nevertheless Brookes's statement is flawed, and it has provoked endless speculation about the nature of information, which has not contributed to an understanding of the problems of IR. (Compare the quotation by Schrader, 1983, p. 99, cited earlier). The worst thing may be that information scientists have overlooked some of the most important theoretical problems in their field.
Van Rijsbergen (1986, p. 194) has pointed out that the concept of meaning has been overlooked in IS. The fundamental basis of all previous work – including his own – is in his opinion wrong because it has been based on the assumption that a formal notion of meaning is not required to solve IR problems. For us it is reasonable to suggest a link between the neglect of the concepts of text and documents on one hand and meaning (or semantics) on the other. Semantics, meaning, text, and documents are much more related to theories about language and literature, whereas information is much more related to theories about computation and control. We do not claim, however, that the statistical methods used in IR have not been efficient.
We do claim, however, that semantics and pragmatics, among other things, are essential to better theoretical development in IR, and in the long run also to the improvement of operational systems. In the literature of IS there is a distinction between document retrieval and fact retrieval.
As a response to a query, a document retrieval system provides a list of references about the subject, which with a certain probability is supposed to contain the answer to the query, or rather to reveal the present documented knowledge about the problem. Fact retrieval systems, on the other hand, are supposed to provide concrete answers to queries. If the query is: 'What is the definition of information science?' A document retrieval system such as Library and Information Science Abstracts ( LISA) produces a long list of papers discussing this issue, whereas a fact retrieval system provide you with one selected definition.
Some distinguished IS researchers have regarded the creation of fact retrieval systems as the ultimate goal of information science. Karen Sparck Jones (1987, p. 9), for instance, claims that 'we are concerned with access and, more materially, indirect access to the information the user wants: he wants the information in the documents, but the system only gives him the documents.'
This statement represents a rather narrow view with roots back to the foundation of documentation and information science. In practice, document retrieval systems coexist with systems that provide concrete answers. Directories, dictionaries, handbooks of chemical and physical constants, and many other kinds of reference works are examples of factographic works and databases that have important functions and exist side-by-side with bibliographic databases. However, we find it important to argue against the view that bibliographical databases or full-text databases should be less than ideal because '[the user] wants the information in the documents, but the system only gives him the documents' (Sparck Jones, 1987, p.9). The idea that bibliographical information systems should be reduced to fact retrieval systems is a problematic assumption. We agree with Rayward that this view is related to a kind of obsolete positivism.
We also see this view as one reason for the use of the terms information and information science. Because it is often desirable to know the source (e.g., in order to compare it with other sources and to evaluate its cognitive authority), document retrieval should not ideally be reduced to fact retrieval systems. This distinction I find philosophically unbased; we here touch upon the fundamental problem of the meaning of meaning and of the nature of signs and symbols.
What is more essential to us, this distinction seems unhappy in actual documentation work. There will, admittedly, be cases in which a document or information center is set up with the exclusive function of providing information concerning physical data, or statistical figures, or exchange rates of currencies, or stock market prices. But even in such cases it applies that neither the person who requests such information nor the person to deliver it should ignore the reliability of data and forget about the general setting in which the data are acquired. An information about some physical property of a material is actually incomplete without information about the precision of some figure and about the conditions under which this figure was obtained. Moreover, various investigations of a property have often led to different results that cannot be compared and evaluated apart from information about their background. An empirical fact always has a history and a perhaps not too certain future.
This history and future can be known only by information from particular documents, i.e. By document retrieval. The so-called fact retrieval centers seem to me to be just information centers that keep their information sources—i.e. Their documents—exclusively to themselves.
(Spang Hanssen, 2001 [1970])”. Romm (1997) shows that there are serious ethical implications involved in defining as something as factual as opposed to meaningful. To the extent that information is seen or presented and legitimized in terms of its supposed factual content, it authorizes a picture of the world — rather than inviting debate on the construction and relevance of the picture. Conversely, insofar as information is treated as a product of specific world-constructing activities, it invites discursive inquiry as to its meaning and relevance.
Are information scientists the only professionals that are working with the 'the generation, collection, organization, interpretation, storage, retrieval, dissemination, transformation and use of information'? (This quote is part of the official definition of information science given by the American Society for Information Science and Technology (Borko, 1968; Griffith, 1980) quoted in full later in this chapter.) We often assume this to be the case. If this is not the case, it seems important to try to specify the special role of information scientists in handling information.
In one sense of the word information, astronomers can be seen as experts who identify, process, and interprets information from the universe. The byproducts of their activities they keep as observations in one form or another. They may make photographs of the universe and of single stars, planets, and galaxies. They also publish their empirical and theoretical findings in journals and other publications. Both the photos and the publications are examples of documents. The library, documentation, and information profession is interested in all kind of documents.
Its core interest and expertise is, however, related to communication of published documents. Our point is that in the sense of the word information as it is used about astronomers' activities, information scientists are not experts for interpreting the information from the stars, but at most are experts in handling information documented by astronomers (e.g., indexing and retrieving astronomical documents). In this example information is defined in a broader sense than usually implied in information science. Just as astronomers can be said to handle information professionally, so it is with other groups. Publishers, researchers, historians, lawyers, and teachers can be said to be professional information handlers in some fashion. Defining information in a way other than implied here can solve this problem. Belkin (1978, p.
60) explicitly seeks to solve this problem by demanding that, “in general, any information concept for information science must refer to at least the specific domain of information science, as indicated by its problem. This means purposeful, meaningful, human communication, with the specific requirements as noted above.”. But this solution has some disadvantages. In information science we are sometimes interested in studying the researcher's selection of an information channel, including whether he or she prefers to go the library or to make an observation for himself. This distinction was made in Taylor's (1968) study on question negotiation and information seeking in libraries. If we define information in the narrow sense, as something belonging solely to information science (as proposed by Belkin), we are not able to make comparative studies of this sort.
Because we find Taylor's questions relevant and consider that he uses the concept of information in a fruitful way, we see a dilemma in using Belkin's (1978) definition in information science (See footnote 7). The role of information specialists may be relatively clear when the target group is, for example, astronomers: information specialists are experts on forms of publications, databases, reference tools, and so forth. In the case of, for example, historians or lawyers, the borders are much less clear because the information that these professions are seeking, interpreting, and using is itself contained in publications and documents. The historian, not the librarian or information specialist, is the expert in seeking, organizing, interpreting, and utilizing the documents needed in his or her professional work. Still, an information specialist has more professional expertise regarding specific maters such as databases, cataloguing. Information science is concerned with the generation, collection, organization, interpretation, storage, retrieval, dissemination, transformation and use of information, with particular emphasis on the applications of modern technologies in these areas. As a discipline, it seeks to create and structure a body of scientific, technological, and systems knowledge related to the transfer of information.
It has both pure science (theoretical) components, which inquire into the subject without regard to application, and applied science (practical) components, which develop services and products.’ (Griffith, 1980, p. 5) (see footnote 8). In our view, this definition does not contain a good identification of the special focus of information science. No science should be defined by its tools (e.g. Modern technologies).
All fields are supposed to utilize the most appropriate tools available. A science should be defined by its object of study. As such, the study of information is a better one. We need, however, to identify the specific role of information science in relation to “the generation, collection, organization, interpretation, storage, retrieval, dissemination, transformation and use of information” as distinct from the activities in which other professionals are more qualified.
In our view, information professionals usually have a broad overview of information sources, sociological patterns in knowledge production, documents types, and so on. They should also have a broader knowledge of the philosophy of science (e.g., paradigms and epistemology), and of the principles of languages use for special purposes.
We believe that the focus of information professionals (as distinct from the professional groups they are serving) implies a sociological and epistemological approach to “the generation, collection, organization, interpretation, storage, retrieval, dissemination, transformation and use of information' (See footnote 9). Information scientists – by the nature of the field – must work in a top-down mode from the general field of knowledge and information sources to the specific, while domain experts must work in a bottom-up mode, from the specific to the general. With regard to the concept of information, the implication is that what count as information – what is informative – depends on the question to be answered. The same representation of an object (e.g., a stone in a field) contains different information for, say, an archaeologist or a geologist. The same matter should therefore be represented differently in different subject databases. The concept of information itself can be defined universalistically (e.g., Bateson, 1972). Information is anything that is of importance in answering a question.
Anything can be information. In practice, however, information has to be defined in relation to the needs of the target groups served by information specialists, not in a universalistic or individualistic, but rather in a collectivist or particularistic fashion. Information is what can answer important questions related to the activities of the target group. The generation, collection, organization, interpretation, storage, retrieval, dissemination, and transformation of information must therefore be based on views/theories about the problems/questions, and goals that the information is going to satisfy. In public libraries, those goals are related to the democratic role of the public library in society. In medicine, they are related to the solving of health problems.
In women’s studies, they are related to the understanding and emancipation of women. In commercial systems, they are bound to business strategy. Outside documentation and library science, in 1948, important developments occurred in so-called information theory, in cybernetics, and in technological theories as well as in communication (Shannon & Weaver, 1949, Wiener, 1948).
These fields build the foundations for subsequent developments in computer science (or information technology) (See footnote 10). It is widely recognized that information theory is a problematic term, and that even the term information technology may be a misleading term for data technology or computer technology. A consequence of Shannon’s theory was that the word information became extremely influential in all areas of society and fashionable in English and other languages. Shannon’s information theory has had an impact on many fields, including library and information science and documentation. The history of this impact or reception has yet to be written. There is no doubt, however, that in the 1950’s many people found that this theory could be used as a very strong conceptual model for research in numerous fields, including psychology, social sciences, and documentation.
Problems with this approach soon appeared (Rapoport, 1953) and the initial optimism disappeared leaving many fields without an adequate theoretical frame. From an information-theoretical point of view information can be precisely defined and measured. For example, Lawrence & Giles (1999) found about 15 terabytes information on the Internet. This is not, however, the same concept as that used by information specialists when seeking, selecting or indexing information sources. These last activities relate to the content and meaning of some messages, not just to their physical storage and transmission.
This was not so in human contexts, where neither the assumption of coherent sets of signs nor the assumption of the identity of original message, signs, and reconstructed message were applicable. The very notion of semiotics, which in fact became one of the most important critiques of too simple an application of information theory to human communication, led to the insight that Shannon's mathematical theory was only a theory on the syntactical level (relation of signs to signs), but with no reference to the semantic (relations of signs to meanings) and pragmatic (relation of signs to humans) levels. In consequence, some attempts were made to develop out of Shannon's theory a semantic (e.g.
Bar-Hillel and Carnap 1953) or pragmatic (e.g. Yovits 1975) information theory. But they remained in the literature with no great success. How relevant is all of this to information science? I suspect that most information scientists are not much concerned with information in Dretske's sense of the word; they are concerned with meaning, not information.
The documents whose storage and retrieval interests them may or may not carry any information, but they do have semantic content or meaning, which is the main thing. If that is so, and if Dretske's notion of information is the 'right' one, then information science is perhaps misnamed. Dretske's idea of information is clearly closer to the 'ordinary' idea of information than is the usual information scientist's idea of information; in the ordinary sense, information is contrasted with misinformation, but not so for the information scientist. It would, I think, be beneficial if some information scientists would take the trouble to read this book, with this question in mind: is information science really concerned with information? And if it is not now, could it be in the future? Wilson's proposal has been heeded.
Van Rijsbergen & Lalmas (1996) are the most prominent followers of Dretske's approach. Together with Barwise (1993) and Devlin (1991), van Rijsbergen and Lalmas (1996, p. 385) call their approach DBD: Dretske, Barwise and Devlin. Van Rijsbergen withdraws his former conclusion that information retrieval is actually document retrieval and tries to develop a theory that bases IR on an objective conception of information. The other references to Dretske's theory in IS (e.g.
Bonnevie, 2001, Loose 1997, Mingers 1995) seem rather unrelated to one another. We have already discussed core definitions of information connected with the cognitive view in information science: Brookes's (1977) pseudo-mathematical expression: K(S) + δ I –>K(S + δ S) and Belkin's (1978, p. 60) definition, which managed to define information as a phenomena relatively specific to information science by viewing information as a communicated and transformed knowledge state in the form of a structure.
Through the work of Brookes (1980), Karl Popper's metaphysical pluralism has been connected to the cognitive view. As is well known, Popper's ontology consists of three worlds. While Freeman and Skolimowski discuss both Peirce's doctrine of signs and Popper's World 3 epistemology, they do not note that the entities comprising Popper's World 3 are signs in the Peircean sense, or that Peirce's doctrine of signs represents a World 3 epistemology that in many respects is more detailed and developed than Popper's; nor has this been noted by any other writer that we are aware of. Again, we do not mean simply that World 3 consists of objects which Peirce would have classified as signs - that would be a rather trivial observation, given the ambitious scope of Peirce's doctrine of signs. Rather, as we have already seen, Popper's own statement that a World 3 object, such as a book, is constituted by its 'dispositional character of being understood or interpreted,' is what recapitulates Peirce's definition of a sign as whatever is capable of being interpreted.
The tendency within and beyond IS has been more to favor of Peirces' semiotic view over Popper's metaphysical pluralism. It makes sense to consider informative objects as signs (as World 1 phenomena) that for some subjects (or “release mechanisms,” which are also World 1 phenomena) trigger some responses (interpretation, selection) and thus introduces teleological principles in the material world (World 1). With the words of Rudd (1983) we simply do not need Poppers’ World 3 in order to explain informational processes. The most recent and loyal description of the cognitive view is presented by Borlund (2000), who is a student of Peter Ingwersen. She finds (p. 16) that Ingwersen adds the concepts of potential information and data 'and in a way the modified model becomes the trademark of Ingwersen, as he in several cases uses it to present an overview of IR interactions'.
We see the cognitive view as taking a position between the objective concept of information in both information theory and Dretske's theory on one hand, and the subjective or interpretative view taken by information scientists inspired by hermeneutics, semiotics, domain analysis, and so forth, on the other hand. Buckland's analysis seems to have two important consequences: On one hand it re-introduces the concept of document ('information as thing') and on the other hand it points out the subjective nature of information. A stump of a tree contains information about its age as well as about the climate during the lifetime of the tree. In similar ways, anything might in some imaginable circumstances be infor-mative: ' We conclude that we are unable to say confidently of anything that it could not be information' (Buckland, 1991, p. Underlining in original). Just as any thing could/might be symbolic, Buckland maintains that any thing could/might be informative/information. The cognitive view is taken one step towards a subjective understanding of information.
Buckland is taking one step further. The domain analytic view sees different objects as being informative relative to the social division of labor in society. In this way, information is a subjective concept, but not primarily in an individual sense. Criteria for what counts as information are formed by sociocultural and scientific processes.
Users should be seen as individuals in concrete situations within social organizations and domains of knowledge. A stone in a field could contain different information for different people. It is not possible for information systems to map all possible information values.
Nor is any one mapping the only 'true' situation. People have different educational backgrounds and play different roles in the division of labor in society. A stone in a field (or, of course, a document about a stone in a field such as a photograph) represents one kind of information for the geologist and another for the archaeologist.
The information from the stone can be mapped onto different collective knowledge structures produced by geology and archaeology. Information can be identified, described, and represented in information systems for different domains of knowledge. Of course, problems arise in determining whether a thing is informative or not for a domain. Other domains have different, conflicting paradigms, each containing its own more or less implicit view of the informativeness of different kinds of information sources. The domain-analytic view is related to a hermeneutic view because the understanding is determined by the pre-understanding of the observer. An explicit 'information hermeneutics' has been developed by Capurro (e.g., 1986).
It is also related to semiotic approaches (e.g. Brier, 1992, 1999) and to the approach know as social constructivism (e.g., Frohmann 1990, 1994; Savolainen, 2000). We should be aware that library and information science is only one discipline among a network of disciplines — including suggested disciplines and metadisciplines — related to communication, technology, systems and processes. We should try to further clarify our identity and our specific goals and to strengthen the historical continuity in the field. We should not consider a concept as information in isolation, but see it in relation to other concepts such as, for example, documents and media. The concept of information may have had a positive effect as a status-raising concept used by professions primarily working with documents.
However, this positive effect has had very unfortunate side effects in raising a level of confusion in the discipline. It is worth noting that important books can be written in the field without using the concept of information (e.g. Lancaster, 1998). Thus, researchers should be explicit on how they define this and any other theoretical terms. It should either be used for the sake of theoretical clarification or — as Fairthorne (1965) recommended — not at all.
There are many concepts of information, and they are embedded in more or less explicit theoretical structures. In studying information it is easy to get lost, i.e. To loose one's orientation. Therefore it is important to state the pragmatic question: 'What differences does it make if we use one or the other theory or concept of information?' This task is difficult because many approaches apply implicit and unclear concepts, which have to be clarified. (Such a clarification may receive resistance because information is often used as a status rising term without much theoretical ambition).
We should also ask ourselves: Given all the information in this paper (and about half a century of research and debate), what more do we need to know about the concept of information in order to contribute to the further development of information science? In our view, the most important distinction in the concepts of information is the distinction between information as an object or a thing (e.g.
Number of bits) and information as a subjective concept, information as a sign, i.e. As depending on the interpretation of a cognitive agent. The interpretation view removes the attention from attributes of things to the 'release mechanisms' for whom those attributes are of importance. This may call frustration, because it is difficult and because it implies teleological principles which are foreign to positivist principles of science. It is relatively easy to count the number of words in a document or describe it in other ways. It is much more difficult to try to figure out for whom that document is of importance, and what the important questions are, that the document can answer. The questions of interpretation are also difficult because we often confuse interpretation with an individualist approach.
Meaning is, however, determined in social and cultural contexts. Finally we want to emphasize the need to explicate the foundations of knowledge claims. When we represent data in our information systems, we do that in order to support certain human activities. We should not just regard our representations as objective, because this implies that we never fully specify the theoretical, social, and historical assumptions on which we act. All kinds of information systems have policies and more or less explicit goals. What we regard as information should finally also be a reflection of the social role of the information system.
As information systems becomes more global and merged implicit information is often lost. This means a challenge for information science that should open its perspective to the social and cultural impact of interpretation processes taking also into account the qualitative differences between different contexts and media.
This means the inclusion of interpretation processes as a conditio sine qua non of information processes. As we have shown several times in this article, this task of interpretation is essentially a multidisciplinary and an interdisciplinary one. Building networks is basically an interpretation process. Building a scientific network as a self-reflective activity presupposes the task of clarifying some common concepts. One of them is the concept of information. The Oxford English Dictionary (1989).
