Describes an expert system that can identify documents erroneously categorized by indexers working within a prior category scheme. The discussion covers the results of a test of the system and its implications for automatic indexing systems. (14 references) (CLB)

Description of a computer system that converts text automatically into a form suitable for browsing and consultation online focuses on its use for online documentation. Also discussed are possibilities for its applications in automatic indexing, index access, and authoring systems for computer-assisted instruction (CAI). (four references)…

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)

Describes the "Rutgers Inventory of Machine-Readable Texts in the Humanities" that provides bibliographic information through RLIN (Research Libraries Information Network) for electronic texts in the humanities. Highlights include adaptation of MARC format; access points; search strategies; and unresolved issues in the bibliographic…

Presents an overview of artificial-intelligence-based inductive learning techniques and their use in information science research. Three methods are discussed: the connectionist Hopfield network; the symbolic ID3/ID5R; evolution-based genetic algorithms. The knowledge representations and algorithms of these methods are examined in the context of…

Describes a project at the Princeton University libraries that converted the pre-1981 public card catalog, using digital imaging and optical character recognition technology, to fully tagged and indexed records of text in MARC format that are available on an online database and will be added to the online catalog. (LRW)

Describes a project that experimented with using a NeXT computer as a cataloger's workstation. The use of Digital Librarian software to access the text of "Anglo-American Cataloging Rules" (AACR) on magneto-optical disk is discussed, and suggestions for future developments are made. (four references) (LRW)

Presents an historical overview of Vannevar Bush's efforts to develop a machine for free-form indexing and computerized information retrieval. Descriptions of the Memex concept and two related machines--the Rapid Selector and the Comparator--are provided; and the shift in emphasis to a device for business or cryptanalytic purposes is discussed.…

Discussion of automatic indexing in information retrieval systems focuses on attempts to improve the indexing representation produced by the FASIT system. Concept selection and concept grouping are explained; improving disambiguation is discussed; and a retrieval experiment to test the effectiveness of the disambiguation using the cystic fibrosis…

Explains the efforts of the ICSTI (International Council for Scientific and Technical Information) Group on Interdisciplinary Searching to identify and describe problems of interdisciplinary searching and to propose solutions. Problems are summarized in six areas: database coverage and technical content, bibliographic information, textual content,…

Presents a theoretical rationale for employing a form of information retrieval algorithm that helps searchers better navigate through large document collections by continually revising probability estimates for document subsets. The algorithm avoids assumptions of index term independence and predicts relevance more accurately with increasing…

Discusses access to nontextual documents in large multimedia document bases. A hybrid information retrieval model, using queries in a hypertext environment for location of browsing areas, is presented; and two experiments using cluster-based descriptions of content are reported. (23 references) (EA)

Discusses and examines two approaches to concept-based retrieval of hypermedia information that improve a user's ability to navigate large systems--term indexing with semantically coupled thesauri and semantic hyperindexing. Visualization of index structures is discussed, and an example, the Cube of Contents retrieval model for the "Active…

Advantages and disadvantages are presented for various voice indexing systems for accessing recorded material for visually impaired people. The Van Schyndel Voice Indexing System, which allows a spoken index to be recorded at regular recording speed, is described, focusing on operation procedures and components of the original and…

Discusses the cost of constructing a hypertext database and suggests cost forecasting approaches that can be used to determine whether organizations can internally fund a hypertext database, or whether producers can afford to market hypertext databases. Production costs in differing hypertext strategies are also compared. (27 references) (LRW)
