Abstract

The conventional methods of full text processing, such as pattern matching and keyword indexing, may result in waste of rich information. Recently, the knowledge-based approach has been used in natural language text processing. Unlike past generations of information retrieval systems which dealt exclusively with abstracts, title headings, and keywords, today’s intelligent information retrieval systems manipulate full texts such as technical manuals, reports, letters, and news articles. This paper discusses the design and implementation of a knowledge-based information retrieval system, concentrating on the issues of knowledge acquisition, knowledge representation, knowledge base refinement, and the information retrieval mechanism
