An algorithm is proposed to solve the problem of sequential indexing which does not use any grammatical or semantic analysis, but follows the principle of emulating human judgement by evaluation of machine-recognizable attributes of structured word assemblies. (Author)

At the Smithsonian Science Information Exchange, a computer system indexes word combinations in research summaries, according to a Classifying Dictionary, prior to review by the professional staff. (Author/PF)

Provides an overview of current newspaper indexing methods, including discussion of those indexes produced by commercial firms, public libraries, newspapers themselves, and news data banks. (FM)

Discusses standards as tools to promote compatibility and improve practice, the role of research versus expert opinion in creating standards, and the changing scope of indexing standards. The current draft of the NISO (National Information Standards Organization) American Standard Guidelines for Indexes in Information Retrieval (Z39.4) is…

Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

A report of several comparisons designed to measure the retrieval effectiveness of machined-aided indexing and manual indexing. (Author)

Examines the knowledge base of an intermediary expert system that provides advice about search term selection. Topics include a proposal for an integrated approach, including an option focusing on terminological attributes based on knowledge acquired from professional searchers; and the content of the knowledge base and the research needed to…

Describes the functions of book and periodical indexes and characteristics of varieties of book indexes. Problems related to periodical indexing including indexing policy, indexing language, depth of indexing, authors' names, titles, the physical form of indexes, indexes to single volumes of periodicals, and cumulative indexes are discussed.…

Goffman's indirect method and a MeSH tree structure were used to classify a set of 109 medical documents. (PF)

Reports research undertaken to conceptualize, design, and implement a system for automatic indexing, classification and repositing of "text items," which may be any aggregate of information in English Language on a computer-readable media, in a standard format. (Author)

Papers on classification and subject cataloging which were presented at the 1983 International Federation of Library Associations (IFLA) conference include: (1) "PRECIS: Basic Principles, Function, and Use," in which Derek Austin (United Kingdom) describes the automated subject indexing system developed for use in the "British…

The technique for machine-aided indexing developed at the Defense Documentation Center (DDC) is illustrated on a randomly chosen abstract. Additional text is provided in coded form so that the reader can more fully explore this technique. (2 references) (Author)

Describes the automatic indexing project undertaken in 1978 to convert by means of a "bridge vocabulary" the terms in the ABI/INFORM database to index terms of a controlled vocabulary. Components of the bridge vocabulary are explained, and examples demonstrating the process of conversion are provided. (JD)

Describes a clustering algorithm designed for dynamic data bases and presents an update procedure which maintains an effective document classification without reclustering. The effectiveness of the algorithms is demonstrated for a subset of the Cranfield collection. (Author)
