Discusses the status of a pilot project undertaken by the ERIC facility to provide access to education-related statistical tapes. Procedures developed for the identification of sources of such tapes, documentation for the tapes, and the creation of surrogate records for cataloging, indexing, and abstracting are described. (seven references) (CLB)

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 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.

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,…

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)

Discusses indexing in large text databases, approximate text searching, and space-time tradeoffs for indexed text searching. Studies the space overhead and retrieval times as functions of the text block size, concludes that an index can be sublinear in space overhead and query time, and applies the analysis to the Web. (Author/LRW)

Indexing is the preprocessing of information to enable its retrieval, ranging from classification-based (precoordinate) to keyword searching (postcoordinate) approaches. This article describes a framework for modelling information retrieval systems in terms of sets of objects, relationships, and functions and discusses the application of indexing…

Proposes a structure for natural language descriptions of the semantic content of visual materials that requires descriptions to be (modified) keywords, phrases, or simple sentences, with components that are grammatical relations common to many languages. This structure makes it easy to implement a collection's descriptions as a relational…

This guide presents the policies and procedures used by the North Dakota State University Libraries for indexing "The Forum," a daily newspaper serving eastern North Dakota and western Minnesota. The guide includes lists of material to be included and excluded, timetables for updating the index, duties of the editor and the library…

This thesaurus is a tool for indexing and retrieving documents and data in the field of education in an international context. Introductory materials include a description of the thesaurus and discussions of its relationship with other thesauri, the thesaurus as an international instrument, its coverage and structure, fields, facets, descriptors…

State of the art access to the literature of women's history is reviewed in this paper, including the issues of publication, bibliographic control, indexing services, and electronic databases. The problems of intellectual access to women's history in online databases are discussed in terms of: (1) characteristics of the subject itself; (2)…

Designed for educators requesting information from ERIC and for the search intermediary who channels educators' requests to a search service, this updated guide explains in non-technical language the steps involved in preparing a computer search for the ERIC database. A beginning section on how to initiate a search discusses the choice of a…

This research project was motivated by results of earlier work (Katzer et al., 1982) on the overlap among document representations. In the earlier study, one representation used in the INSPEC database proved to perform unexpectedly well in comparison with other commonly used representations, such as controlled vocabulary or free-text terms from…

Benchmarking is one of several alternate methods of performance evaluation, which is a key aspect in the selection of database systems. The purpose of this report is to provide a performance evaluation methodology, or benchmarking framework, to assist in the design and implementation of a wide variety of benchmark experiments. The methodology,…
