Wajenberg, Arnold S. – Information Technology and Libraries, 1983
Recommends an expansion of MARC codes for decimal class numbers to enhance automated subject retrieval. Five values for a second indicator and two new subfields are suggested for encoding hierarchical relationships among decimal class numbers. Additional subfields are suggested to enhance retrieval through analysis of synthesized numbers in…

Gillaspie, Deborah L. – Proceedings of the ASIS Annual Meeting, 1992
Discusses a study in progress that is analyzing retrieval failures in two full-text computer-assisted legal research (CALR) systems, LEXIS and WESTLAW. Computer searching by experts is compared with manual searching by experts, examples are given, and a taxonomy of causes of retrieval failure is discussed. (13 references) (LRW)

Svenonius, Elaine – Library Resources and Technical Services, 1983
Six uses of classification in online retrieval systems are envisioned--to improve recall and precision; to conceptualize meaning of vague search terms; to provide structure for browsing; to provide framework for retrieval of nonbibliographic information; to collocate citations; and to achieve compatibility of retrieval languages. Seven sources are…

Dillon, Martin; Federhart, Peggy – Journal of the American Society for Information Science, 1984
Discusses ways to improve quality of retrieval systems that depend on use of truncated words or quasi-word stems as indexing vocabulary. Problems of generalizability and stability of discriminant function analysis for selecting good topical terms in database drawn from abstracts of Harris Survey press releases are addressed. References are cited.…

Srinivasan, Padmini; Ruiz, Miguel E.; Lam, Wai – Proceedings of the ASIS Annual Meeting, 1996
Proposes a model that assists in understanding indexing on the World Wide Web and presents an experiment assessing the validity of Inverse Document Frequency (IDF) as a term weighting strategy for Web documents. Findings indicate that IDF scores are not stable in the heterogeneous and dynamic context of the Web. (Author/AEF)
