KNOWLEDGE REPRESENTATION: A BRIEF REVIEW

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, categories and relations in subject anlaysis, 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.
