Describes a prototype system--GeoMatch--that allows users to interactively define geographic areas of interest on a background map and to define, qualitatively or quantitatively, the relationship between the user-defined area and the map coverage. The knowledge discovery in database (KDD) factor is analyzed in the retrieval process. The MARC…

Explores the qualities of bibliographic and object entities that contribute to the similarities and differences in the data describing them and the possibility of cooperation between indexers of art objects and indexers of bibliographic information. The discussion covers the role of authority control as the linking component between bibliographic…

Examines some medical classification systems with a long history--notably the "International Classification of Diseases (ICD)." States that this classification scheme retains many traces of its own administrative and organizational past in its current form. Suggests that ICD, like other large-scale classification systems, performs so…

Source documents which aid in assessing social statistics are listed. A sample abstract from the directory and six references are appended. (EJS)

Analysis of one component of library reference service--online numeric database systems for time-series data--reviews tradition of reference service and ways in which computer technology has enhanced provision of library services. Experiences with Kentucky Economic Information System (KEIS) are described. Examples of KEIS and 30 references are…

Suggests that preliminary findings from research on intellectual access to digital images indicate a need for improved browsing tools, image manipulation software, feedback mechanisms, and query analysis. Discusses problems of image retrieval identified in current research, reports on an evaluation project in process, and proposes a framework for…

Finding information on the Web without encountering numerous false positives poses a challenge to multimedia information retrieval systems (MMIR). This research focuses on improving precision and recall in an MMIR system by interactively combining text processing with image processing in both the indexing and retrieval phases. A picture search…

Discusses issues connected with developing information systems for competitive intelligence support; defines the elements of an effective competitive information system; and summarizes issues affecting system design and implementation. Highlights include intelligence information; information needs; information sources; decision making; and…

Libraries should be active participants in knowledge production, and should develop classificatory structures that support the needs of a diverse information ecology consisting of a complex web of interacting agents, users, and technologies. Within such an information ecology, a classificatory structure cannot follow a one-size-fits-all paradigm,…

Reviews studies of clinicians' information-seeking behavior and discusses various library programs and services designed to deliver information to clinicians.
