Shneiderman, Ben – Proceedings of the ASIS Annual Meeting, 1991
Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

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)

Saracevic, Tefko – Proceedings of the ASIS Annual Meeting, 1991
Synthesizes major findings from research on the magnitude of individual differences in information retrieval (IR) tasks and suggests implications for practice and design of IR systems and interfaces. Topics discussed include indexing consistency, relevance judgments, selection of subject headings, selection of search terms, and search retrievals.…

Tudhope, Douglas; Taylor, Carl – Proceedings of the ASIS Annual Meeting, 1996
Describes an integrated approach to similarity coefficients that allows multiple index dimensions to be integrated into a single, flexible navigation tool. Categorizes different types of similarity measures by the kinds of index terms they employ and describes the underlying similarity measures. (Author/AEF)

Hersh, William R.; And Others – Proceedings of the ASIS Annual Meeting, 1995
Describes a task-oriented assessment of two MEDLINE searching systems by medical students, one using Boolean searching on human-indexed thesaurus terms and one using natural language searching on words in the title, abstract, and indexing terms. Highlights include user certainty in answering questions, time needed, and user satisfaction.…

Hersh, William R.; Hickman, David H. – Proceedings of the ASIS Annual Meeting, 1992
Describes a study that compared two information retrieval systems on a full-text medical database: one featured concept-based automatic indexing and statistical retrieval techniques, and the second used traditional word-based Boolean techniques. Evaluation of search results by calculating relative recall and precision is discussed, and user…
