- 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
- 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
- This experiment, focused on the users behaviour, aims to study the search topic representation they build and to highlight the role of a graphical thesaurus on their mental models and searching behaviour. The users expertise in the field is considered. The results show how difficult it is to structure a field; they also point out how much a graphical thesaurus could contribute to such a task, but also its restricted role in the query task. They urge us to think over which shape is proper to the conceptual interface and the variety of links that have to be taken into account

- Abstract
- Based upon the existing cognitive theories and available related literature, the hypothesis "Conceptualisation process involves a set of specific cognitive skills" has been evolved. An attempt has been made to identify these cognitive skills that are directly involving in conceptualisation process and the outcome is the identification of 13 cognitve skills that are essential for conceptualisation process. This research is directed towards evolving a new concept classification to facilitate learning and teaching. Here we classify the concepts into six categories based upon their attributes and attribute's relations. A specific "Concept analysis ability" tool is also developed to measure the 'concept analysis ability' of secondary school teachers

- 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

- 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
- In this chapter I propose that frames provide the fundamental representation of knowledge in human cognition. In the first section, I raise problems with the feature list representations often found in theories of knowledge, and I sketch the solutions that frames provide to them. In the second section, I examine the three fundamental concepts of frames: attribute-value sets, structural invariants, and constraints. Because frames also represents the attributes, values, structural invariants, and constraints within a frame, the mechanism that constructs frames builds them recursively. The frame theory I propose borrows heavily from previous frame theories, although its collection of representational components is somewhat unique. Furthermore, frame theorists generally assume that frames are rigid configurations of independent attributes, whereas I propose that frames are dynamic relational structures whose form is flexible and context dependent. In the third section, I illustrate how frames support a wide variety of representational tasks central to conceptual processing in natural and artificial intelligence. Frames can represent exemplars and propositions, prototypes and membership, subordinates and taxonomies. Frames can also represent conceptual combinations, event sequences, rules, and plans. In the fourth section, I show how frames define the extent of conceptual fields and how they provide a powerful productive mechanism for generating specific concepts within a field.

- 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
- 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
