Abstract

Up to the present day, difficulties have confronted all attempts at establishing a theory of concepts that would comprise the various kinds of concept-formation in the disciplines of the spectrum of sciences. Not a few philosophical dictionaries, under the entry 'concept', still offer doctrinies which were current far back in the history of philosophy and have little in coomon with concept-formations in the sciences today. The paper aims at an improvement in this situation. After a sketch of the 'classical' notion of concept, already developed in antiquity (essentially a logic of 'classification', although 'class-formation' in tis present understanding had not yet been conceived), the canonical modern doctrine of concepts is outlined. With an eye to application in the exact sciences, it is shown how in the nineteenth century the view of concept as an additive complex of characteristics yields to a functional approach systematized, in the last quarter of the century, by classical quantificational logic. Almost simultaneously, Mach, Frege, Peano, Weyl and others set out to shape the modern theory of abstraction. It is these two theories that today permit philosophers of science not only to deal with functional processes of concept-formation but also to represent in a formally coorect manner metalinguistic propositions about concepts and their properties. Thus it seems that the fundamental tasks of a modern theory of concept have finally been taken care of

Abstract

The aim of this paper is to analyze the Gottlob Frege's (1848-1925) theory of definition as a tool for knowledge organization. The objective was achieved by discussing the theory of definition including: the aims of definition, kinds of definition, condition of correct definition, what is undefinable. Frege indicated the following aims of a defining: (1) to introduce a new word, which has had no precise meaning until then (2) to explain the meaning of a word; (3) to catch a thought. We would like to present three kinds of definitions used by Frege: a contextual definition, a stipulative definition and a piecemeal definition. In the history of theory of definition Frege was the first to have formulated the condition of a correct definition. According to Frege not everything can be defined, what is logically simple cannot have a proper definition Usability of Frege's theory of definition is referred in the case study. Definitions that serve as an example are definitions of 'context'. The term 'context' is used in different situations and meanings in the field of knowledge organization. The paper is rounded by a discussion of how Frege's theory of definition can be useful for knowledge organization. To present G. Frege's theory of definition in view of the need for knowledge organization we shall start with different ranges of knowledge organization.

Abstract

Concept theory is an extremely broad, interdisciplinary and complex field of research related to many deep fields with very long historical traditions without much consensus. However, information science and knowledge organization cannot avoid relating to theories of concepts. Knowledge organizing systems (e.g., classification systems, thesauri, and ontologies) should be understood as systems basically organizing concepts and their semantic relations. The same is the case with information retrieval systems. Different theories of concepts have different implications for how to construe, evaluate, and use such systems. Based on a post-Kuhnian view of paradigms, this article put forward arguments that the best understanding and classification of theories of concepts is to view and classify them in accordance with epistemological theories (empiricism, rationalism, historicism, and pragmatism). It is also argued that the historicist and pragmatist understandings of concepts are the most fruitful views and that this understanding may be part of a broader paradigm shift that is also beginning to take place in information science. The importance of historicist and pragmatic theories of concepts for information science is outlined.

Abstract

This article presents the semantic information theory, formulated by the philosopher Fred I. Dretske, as a contribution to the discussion of metatheories and their practical implications in the field of library and information science. Dretske's theory is described in Knowledge and the flow of information. It is founded on mathematical communication theory but developed and elaborated into a cognitive, functionalistic theory, is individually oriented, and deals with the content of information. The topics are: the information process from perception to cognition, and how concept formation takes place in terms of digitisation. Other important issues are the concepts of information and knowledge, truth and meaning. Semantic information theory can be used as a frame of reference in order to explain, clarify and refute concepts currently used in library and information science, and as the basis for critical reviews of elements of the cognitive viewpoint in IR, primarily the notion of "potential information". The main contribution of the theory lies in a clarification of concepts, but there are still problems regarding the practical applications. More research is needed to combine philosophical discussions with the practice of information and library science.

Abstract

Relationships can provide a rich and powerful set of information and can be used to accomplish application goals, such as information retrieval and natural language processing. A growing trend in the information science community is the use of information visualization-taking advantage of people's natural visual capabilities to perceive and understand complex information. This chapter explores how visualization and visual exploration can help users gain insight from known relationships and discover evidence of new relationships not previously anticipated.

Abstract

Interdisciplinary communication, and thus the rate of progress in scholarly understanding, would be greatly enhanced if scholars had access to a universal classification of documents or ideas not grounded in particular disciplines or cultures. Such a classification is feasible if complex concepts can be understood as some combination of more basic concepts. There appear to be five main types of concept theory in the philosophical literature. Each provides some support for the idea of breaking complex into basic concepts that can be understood across disciplines or cultures, but each has detractors. None of these criticisms represents a substantive obstacle to breaking complex concepts into basic concepts within information science. Can we take the subject entries in existing universal but discipline-based classifications, and break these into a set of more basic concepts that can be applied across disciplinary classes? The author performs this sort of analysis for Dewey classes 300 to 339.9. This analysis will serve to identify the sort of 'basic concepts' that would lie at the heart of a truly universal classification. There are two key types of basic concept: the things we study (individuals, rocks, trees), and the relationships among these (talking, moving, paying).

Abstract

Much of the literature of information science and knowledge organization has accepted and built upon Elaine Svenonius's (2004) claim that "paradigmatic relationships are those that are context-free, definitional, and true in all possible worlds" (p. 583). At the same time, the literature demonstrates a common understanding that paradigmatic relations are the kinds of semantic relations used in thesauri and other knowledge organization systems (including equivalence relations, hierarchical relations, and associative relations). This understanding is problematic and harmful because it directs attention away from the empirical and contextual basis for knowledge-organizing systems. Whether A is a kind of X is certainly not context-free and definitional in empirical sciences or in much everyday information. Semantic relations are theory-dependent and, in biology, for example, a scientific revolution has taken place in which many relations have changed following the new taxonomic paradigm named "cladism." This biological example is not an exception, but the norm. Semantic relations including paradigmatic relations are not a priori but are dependent on subject knowledge, scientific findings, and paradigms. As long as information scientists and knowledge organizers isolate themselves from subject knowledge, knowledge organization cannot possibly progress.

Abstract

Purpose The purpose of this paper is to discuss the literature on concept theory in library and information science (LIS) from an epistemological perspective, ascribing each paper to an epistemological family and discussing their relevance in the context of the knowledge organization (KO) domain. Design/methodology/approach This paper adopts a hermeneutic approach for the analysis of the texts that compose the corpus of study following contingency and categorical analyses. More specifically, the paper works with Bardin's contingency analysis and follows Hjørland's families of epistemologies for the categorization. Findings The analysis corroborates the observations made for the last ten years about the scarcity of studies on concept theory in LIS and KO. However, the study also reveals an epistemological turn on concept theory since 2009 that could be considered a departure from the rationalist views that dominated the field and a continuation of a broader paradigm shift in LIS and KO. All analyzed papers except two follow pragmatist or historicist approaches. Originality/value This paper follows-up and systematizes the contributions to the LIS and KO fields on concept theory mainly during the last decade. The epistemological analysis reveals the dominant views in this paradigm shift and the main authors and trends that are present in the LIS literature on concept theory.
