Towards Everyday Language Information Retrieval Systems via Minicomputers.
Peer reviewed Peer reviewed
Bell, Colin; Jones, Kevin P. – Journal of the American Society for Information Science, 1979
Surveys the current state of minicomputer-operated information systems capable of incorporating linguistic features, focusing on the Minicomputer Operated Retrieval (Partially Heuristic) System. Consideration is given to the automation of the indexing process and to available search strategies. (FM)

Retrieving Records from a Gigabyte of Text on a Minicomputer Using Statistical Ranking.
Peer reviewed Peer reviewed
Harman, Donna; Candela, Gerald – Journal of the American Society for Information Science, 1990
Describes the advantages of a prototype retrieval system that uses statistically based ranked retrieval of records rather than traditional boolean methods, especially for end users. Several new techniques are also discussed including bit mapping, pruning, methods of building inverted files, and types of search engine. (26 references) (EAM)

Kantor, Paul B. – Annual Review of Information Science and Technology (ARIST), 1994
Identifies current trends in the automation of indexing, of information retrieval, and of interaction between the system and the users. Topics discussed include location, navigation, and indexing; digital libraries; matching documents to queries; weight of concepts; query structure, including fuzzy sets; algorithms; stemming; clustering; users'…
