Reports on a study of user-based relevance interpretations which considered the nature of users' thought processes in evaluating bibliographic citations produced by a document retrieval system. Factors found to be important include an individual's subject knowledge, professional training, educational background, anticipated usage of documents,…

Organized from the viewpoint of information retrieval theory, this review addresses issues of chemical information representation, comparison and matching, and retrieval strategies. Additional topics include similarity and clustering, visualization, and molecular diversity. Trends in research and application are identified, and gaps in the…

Describes a study conducted at Illinois State University that compared the results achieved by library users searching the ERIC database on CD-ROM with the results achieved by individual and teamed skilled intermediaries. Evaluation of library services is discussed, patron search strategies are examined, and strategies for improving patron…

This paper explores the fault-tree analysis approach to isolating failure modes within a system. Fault tree investigates potentially undesirable events and then looks for failures in sequence that would lead to their occurring. Relationships among these events are symbolized by AND or OR logic gates, AND used when single events must coexist to…

Reviews the literature on user studies in both online catalogs and bibliographic retrieval systems. User problems with both mechanical and conceptual aspects are reviewed and potential sources of problems due either to individual characteristics or system variables are discussed. Possible solutions and areas that need further research are noted.…

Defines artificial intelligence (AI) and expert systems; describes library applications utilizing AI to automate creation of document representations, request formulations, and design and modify search strategies for information retrieval systems; discusses expert system development for information services; and reviews impact of these…

This study focused on how CD-ROM systems were being used in a college library and training users had received or assistance they required. Patrons completed surveys and librarians logged assistance requests to determine the level of assistance needed for CD-ROM workstations. Results showed most patrons need assistance from librarians even for…

Considers the success and satisfaction of end users' searches on CD-ROM systems.

Presents literature review of concept-based search theory and its relationship to end user instruction for online bibliographic information systems. Existing search models and search curriculums from the library and information science literature are surveyed, scholarly patterns of information access are discussed, and commercial sources of…
