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)

Outlines a cognitive process model of abstracting, indexing, and classification that is based on text comprehension processes. Text comprehension for indexing versus other purposes is discussed, including conceptual and perceptual processing; conceptual knowledge and the development of expertise are discussed; and characteristics of short-term and…

This multi-part bibliographic essay identifies the most relevant issues about the publishing of scholarly electronic journals: access, cataloging and indexing, pricing, archiving, and licensing. Each section highlights the current debates on the topic and provides references to sources of further study. (Author/LRW)

Discusses research dealing with the cognitive aspects of formal systems of knowledge representation. Highlights include the origins and theoretical foundations of the cognitive viewpoint; cognition and information science; cognitivism, mentalism, and subjective individualism; categorization; mental models; and sociocognitive approaches to indexing…
