Conventional and Knowledge-Based Information Retrieval with Prolog.
Peer reviewed Peer reviewed
Leigh, William; Paz, Noemi – Information Technology and Libraries, 1988
Describes the use of PROLOG to program knowledge-based information retrieval systems, in which the knowledge contained in a document is translated into machine processable logic. Several examples of the resulting search process, and the program rules supporting the process, are given. (10 references) (CLB)

Measuring the Performance of a Merging Algorithm: Mismatches, Missed-Matches, and Overlap in Israel's Union List.
Peer reviewed Peer reviewed
Meir, Daniel D.; Lazinger, Susan S. – Information Technology and Libraries, 1998
Reports on a survey measuring the performance of a merging algorithm used to generate the now-defunct ULM (Union List of Monographs) file for ALEPH, Israel's research library network. Discusses automatic detection and merging of duplicate bibliographic records, problems created by lack of a standard for Hebrew spelling, and methods for measuring…
