Abstract

Interactice knowledge-based indexing of the National Library of Medicine's MEDLINE database is advocated. It is established that in the current setting concept indexing is needed and cannot be fully automated. Compatibility between conventional and knowledge-based indexing is highlighted, followed by discussion of indexing as a cognitive process. The section of knowledge-based indexing describes how NLM's MedIndEx prototype addresses problems in conventional indexing and includes the contention that constructing a knowledge base adapted from a conventional classified thesaurus and indexing scheme is not as daunting as it may seem. Extension of the prototype to an intelligent search assistant illustrates use of the same knowledge base to integrate indexing and retrieval applications. Suggested are also future directions for knowledge-based indeing
