Abstract

A method (HICLAS, DeBoeck & Rosenberg, 1988) for studying the internal structure of semantic concepts is presented. The proposed method reveals the internal structure of the extension as well as the intesion of a concept, together with a correspondence relation that shows the mutual dependence of both structures. Its use is illustrated with the analysis of simple concepts (e.g. sports) and conjunctive concepts (e.g. birds that are also pets). The underlying structure that is revealed can be interpreted as a differentiation of the simple concepts studied and for conjunctive concepts the proposed method is able to extract non-inherited and emergent features (Hampton, 1988)

Abstract

The importance of 'concept' in the study of terms is recognized by most researchers in the field of terminological research. However, the theoretical status of 'concept' in the study of terms has not been clarified so far. Against this background, the status of 'concept' in the study of terms is theoretically examined in comparison with the status of 'meaning' in the semantic study of general languages. Sketches a possible scheme by which 'concept' and 'meaning' are properly plyced in the theoretical study of terms

Abstract

Analyses the concepts species, class and set to explain the development of generic arrangement beginning with Aristotle's theory of essences. Explains the development from Aristotelian essences to the acceptance of accidental characteristics, culminating in the logical algebra of Boole and in a distinction between classes (as the extension of a concept) and sets (as a grouping of elements). Discusses 2 problems relating to indexing theory, selected from PRECIS and the work of Das Gupta

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

Surveys ontological questions that arise in artificial intelligence, some of the answers that have been proposed by various philosophers, and an application of the philosophical analysis to the clarification of some current issues in artificial intelligence. Charles Sanders Peirce and Alfred North Whitehead have developed the most complete systems of categories. Their analyses suggest a basic structure of categories that can provide some guidelines for the design of artificial intelligence systems

Abstract

A model for standardizing existing definitions and/or writing new definitions for thesaurus descriptors has been developed, within the framework of a research project concerned with the usefulness of terminological definitions for indexers working with a thesaurus. The proposed model is an expansion of a model presented by Sager and L'Homme in 1994. Examples of its application in a thesaurus describing the field of Adult literacy programming and training are introduced

Abstract

Intended is first of all a preliminary review of the implications that the new approaches to the theory of classification, mainly from cognitive psychology and epistemology may have for information work and research. As a secondary topic the scientific relations existing among information science, epistemology and the cognitive sciences are discussed. Classification is seen as a central activity in all daily and scientific activities, and, of course, of knowledge organization in information services. There is a mutual implication between classification and conceptualization, as the former moves in a natural way to the latter and the best result elaborated for classification is the concept. Research in concept theory is a need for a theory of classification. In this direction it is of outstanding importance to integrate the achievements of 'natural concept formation theory' (NCFT) as an alternative approach to conceptualization different from the traditional one of logicians and problem solving researchers. In conclusion both approaches are seen as being complementary: the NCFT approach being closer to the user and the logical one being more suitable for experts, including 'expert systems'

Abstract

After studying the relations between two words(nouns) that constitute a compound term, the relation between corresponding concepts discussed. The impossibility of having a conjunction between two concepts that have no common feature causes inconvenience in the application of concept theory to information retrieval problems. Another kind of conjunctions, different from that by co-occurrence, is proposed and characteristics of this conjunction is studied. It revealed that one of new ones has the same character with colon combination in UDC. The possibility of having three kinds of conjunction including Wsterian concept conjunction is presented. It is also discussed that subdivisions can be replaced by new conjunctions

Abstract

Examines the nature of knowledge and the relationship between the transfer of knowledge and information communication. Discusses the 3 kinds of relationships existing between concepts: formal; form-categorical; and material relationships, and characteristics of concepts. Concludes with a discussion of conceptual structures for concept definitions, conceptual systematization , concept systematization and functionality, and the analytical, referent-oriented concept theory

Abstract

Defends the systematic introduction of formal ontological principles in the current practice of knowledge engineering, and explores the various relationships between ontology and knowledge representatiom. Presents recent trends in this research area. Compares the dichotomy between reasoning and representation to the philosophical distinction between epistemology and ontology. Introduces the notion of the ontological level, intermediate between the epistemological and conceptual levels as a way to characterize a knowledge representation formalism taking into account the intended meaning of its primitives

Abstract

Considers language to be a multidimensional object and presents a dynamic model of language, employing a predication chain. The model, in addition to its theoretical value, has several practical uses, including text condensation

Abstract

A new comprehensive taxonomy of all kinds of aspects (such as attribute, characteristic, feature, property and quality) is proposed, and concise, uniform names are suggested for the respective concepts. Based on this taxonomy, a new semantic network notation called ETA is briefly introduced
