- Abstract
- The problems of representing knowledge in computer systems are common to information science, artificial intelligence, psychology and linguistics. The paper offers a brief review of the structures and techniques that have been developed in these different disciplines. It looks at the semantic structure of sentences, at roles, catagories and relations in subject analysis, at semantic primitives, and at knowledge representation for reasoning. The paper concludes with a note on a prototype expert system that makes use of some of these techniques

- Abstract
- Brian C. Vickery, Director and Professor, School of Library, Archive and Information Studies, University College, London, is a prolific writer on classification and information retrieval. This paper was one of the earliest to present initial efforts by the Classification Research Group (q.v.). In it he clearly outlined the need for classification in subject indexing, which, at the time he wrote, was not a commonplace understanding. In fact, some indexing systems were made in the first place specifically to avoid general classification systems which were out of date in all fast-moving disciplines, especially in the "hard" sciences. Vickery picked up Julia Pettee's work (q.v.) an the concealed classification in subject headings (1947) and added to it, mainly adopting concepts from the work of S. R. Ranganathan (q.v.). He had already published a paper an notation in classification, pointing out connections between notation, words, and the concepts which they represent. He was especially concerned about the structure of notational symbols as such symbols represented relationships among subjects. Vickery also emphasized that index terms cover all aspects of a subject so that, in addition to having a basis in classification, the ideal index system should also have standardized nomenclature, as weIl as show evidence of a systematic classing of elementary terms. The necessary linkage between system and terms should be one of a number of methods, notably:
