Knowledge acquisition for concept indexing in document retrieval

Source

Expert systems for information management. 5(1992) no.1, S.25-41

Year

Abstract

Describes TWIG, a system for knowledge acquisition from text for use in an intelligent document database system. Documents are scanned into the system and converted into a hypertext thus providing a richer environment for browsing and retrieval. The knowledge acquisition phase is blackboard based with the text analysis expertise partitioned into agents that communicate through the blackboard
