Reviews of literature are conducted within academia to summarize and highlight gaps in findings and research approaches associated with a particular line of inquiry. Identifying sources to be included in reviews in rigorous ways can be challenging for interdisciplinary research topics, as relevant articles may be found in a wide variety of…

Reports on a study of the information-seeking behavior of users of Infotrac, OCLC, Newsbank Electronic Index, and LS/2 at the Bowling Green State University Libraries. Data gathered via interviews are discussed as they pertain to the user's profile; understanding of systems functions; effects on information-seeking behavior; and appropriateness of…

Discusses the relationship between information science research and practice and briefly describes current research on 10 topics in information retrieval literature: vector processing retrieval strategy, probabilistic retrieval models, inverted file procedures, relevance feedback, Boolean query formulations, front-end procedures, citation…

Presents the advantages and disadvantages of free text and controlled vocabulary retrieval techniques and a methodology to assist in deciding on the optimal technique for a particular purpose. The relevance of the techniques for expert systems and full text contexts is also discussed and recommendations for further research are made. (Author/EM)

Discusses the overlap of research in artificial intelligence and information retrieval, focusing on the papers included in this special issue of Information Processing and Management. Highlights include the emphasis on evaluation and testing in prior research and use of manual and automatic indexing, expert systems, knowledge representation, and…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

Analyzes computerized reference and information services with respect to problems in the areas of (1) communication barriers between the user and the information specialist; (2) local resources development; (3) external resources policy; (4) search strategy development; and (5) artificial intelligence. (24 references) (Author/MES)

Explores the potential usefulness of the Library of Congress Classification (LCC) system as a tool in online retrieval. Unique features of LCC are described and a theoretical analysis of its potentials and limitations in terms of subject browsing, enhanced vocabulary, and class number searching are presented. (CDD)

This review of the research on the use of card catalogs and online catalogs highlights research methodologies and significant findings. Discussion of the results focuses on user needs and satisfaction, and the need to separate bibliographic practices that are universally sound from those that are an adaptation to the medium. (CLB)

This review of the literature on the effect of information overload on users' information-seeking behavior focuses on librarians' opinions about the number of references that constitute too many, and users' preferences for maximum numbers of references from online searches, online public access catalog postings, and manual indexes. (35 references)…

Presents results of five experiments on human information-seeking behavior in different online information-seeking environments which studied search strategies and assessed information value in realistic search environments. A conceptual model of how humans value information is presented. Empirical and modeling results are considered for…

This examination of misunderstandings between librarians and teaching faculty over concepts of library use and research concludes that library skills and research skills are essentially different things that can be learned in isolation from each other. Implications of these findings for bibliographic instruction and library policies are discussed.…

Discusses formulation of value function based on research from modelling, value assessment, human information seeking behavior, and human decision making. The proposed function is incorporated into computer-based fiction retrieval system and evaluated based on ability of individual's value function to discriminate among novels selected, rejected,…

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.…
