Knowledge discovery in databases (KDD) revolves around the investigation and creation of knowledge, processes, algorithms, and mechanisms for retrieving knowledge from data collections. The article is an introductory overview of KDD. The rationale and environment of its development and applications are discussed. Issues related to database design…

Examines the Museum Educational Site Licensing (MESL) Project--a cooperative project between seven cultural heritage repositories and seven universities--as well as other developments of cultural heritage image databases for academic use. Reviews recent literature on image indexing and retrieval, interface design, and tool development, urging a…

The link between classification and knowledge is explored. The strengths and limitations of four classificatory approaches (hierarchies, trees, paradigms, and faceted analysis) are described in terms of their ability to reflect, discover, and create new knowledge. Examples are provided of the way in which knowledge and the classification process…

Drawing upon an efficacious method for discovering previously unknown causes of medical syndromes and searching in the Humanities Index, an illuminating new humanities analogy between the epistemological ideas of Robert Frost and the ancient Greek philosopher Carneades was found by constructing a search statement in which proper names were coupled…

Presents overview of commercially available databases useful to field of mental health. The availability, costs, coverage, currency, update frequency, and access points are compared for four major files--PsychINFO, National Clearinghouse for Mental Health Information, Social SciSearch, and MEDLINE. Forty-nine references are provided. (EJS)

Presents a method for extracting maximal frequent sequences in a set of documents. A maximal frequent sequence is a sequence of words that is frequent in the document collection and is not contained in any other longer frequent sequence. Frequent maximal sequences can be used as content descriptors for documents. (MES)

Describes major changes made in bibliographic control systems in the past three decades and discusses why these changes have occurred. (Author)

Describes a project for the creation of an indexing system for architectural drawings that will allow integration of bibliographic and intellectual access to the collection using an existing online library information network. The discussion covers the influence of archival, curatorial, and library traditions on the project. (11 references) (CLB)

Presents various levels of criteria for judging the quality of abstracts and abstracting. Requirements for abstracts to be read by humans are compared with requirements for those to be searched by computer. Concludes that the wide availability of complete text in electronic form does not reduce the value of abstracts for information retrieval.…

Considers aspects of building, maintaining, and using United States MARC format and other related standards, discussing costs and benefits, MARC and the American National Standards Institute's Z39 standard, effects of MARC on content and processing, compatibility between and within standards, and MARC in practice. Nineteen sources are cited. (EJS)

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…

Describes access and retrieval techniques implemented as part of a research and development program in electronic imaging applied to document storage and retrieval at the National Library of Medicine. Design considerations for large image databases are discussed. (six references) (EAM)

Presents a methodology for creating pathways through the scientific literature following strong cocitation links. A path is described starting in economics and ending in astrophysics, traversing 331 documents. Attention is given to where the path crosses disciplinary boundaries and how analogy can be used to model the thought processes involved in…

History, development, evaluation, and problems of computerized biomedical information systems, with emphasis on the National Library of Medicine and MEDLARS. (LS)

Discusses the importance of machine-readable data files (MRDF) in social sciences reference exchange and provides examples of their use in typical library settings. Access to and available MRDF are described. Nine references are included. (EJS)
