Reviews the state of the art in automatic indexing, concentrating on the literature from 1968 to 1973. (Author/PF)

Reports a computer assisted index emphasizing expanded subject access to the reference collection of the Iowa State University Library. The index displays abbreviated length records and complements existing catalogs. Limitations of subject access and a system for assigning subject descriptors are discussed. (Author/RAA)

Although a large part of a document retrieval system's resources are devoted to indexing, the question of how people do subject indexing has been the subject of much conjecture and only a little experimentation. This dissertation examines the relationships between a document being indexed and the index terms assigned to that document in an attempt…

Suggests the designation of overlapping hierarchies in thesauri, first outlined in 1973, as a key element in progress towards a successful man-machine partnership. Article updates, expands, and provides theoretical background of 1973 proposal; postulates use of the UDC; and suggests means of distinguishing overlapping terms from other…

Describes MANIS, an information system for retrieval of interdisciplinary information in management, which maintains traditional classification but allows the user to combine terms of his choice, where choice is restricted to terms belonging to the systems of traditional classification. (CWM)

Describes a new text analysis approach to automate the indexing process, i.e., an automated keywording system designed to behave as a human expert indexer, and explains the rule base of the approach, which consists of lists of insertion and deletion rules generated by subject matter experts.

The four chapters included in this report are based on LINCS project activities undertaken since 1968, with an emphasis on indexing tools in the language sciences and related problems. Chapter one, "Indexing Tools for the Language Sciences: Methodology," discusses the development of a LINCS thesaurus and its role in the LINCS network.…

These two indexing systems are briefly described and experimental evidence is cited showing that a combination of both theories produces better retrieval performance than either one alone. Appropriate conclusions are reached concerning viable automatic indexing procedures usable in practice. (Author)

Investigates the influence of index term distributions and indexing exhaustivity on the document space within a visual information retrieval environment called DARE (Distance Angle Retrieval Environment). Discusses results that demonstrate the importance of term distribution and exhaustivity on the density of document spaces and their implications…

Proposed is a measure of indexing consistency based on the concept of "fuzzy sets." By this procedure a higher consistency value is assigned if indexers agree on the more important terms than if they agree on less important terms. Measures of the quality of an indexer's work and exhaustivity of indexing are also proposed. Experimental data on…

Demonstrates application to art literature of indexing system which involves conceptual analysis of content and characteristics of documents using descriptors assigned to facets of the discipline and its literature. Indexing vocabulary and syntax, alphabetical and classified indexes, and exhaustivity of indexing are discussed. Sample indexes and…

An experiment to compute and analyze the degree of association between descriptors used to index a document collection of approximately 40,000 records is described. An analysis of the results is presented which indicates the difficulties inherent in applying the results to an operating system. (11 references) (Author)

A detailed guide on how to index slides using descriptors and on how to search the file once it is prepared. (AA)

Investigated the impact of term frequencies, term distributions, and indexing exhaustivity on the representation of document spaces in a visual, vector-based retrieval environment. Compares document-space densities and discusses visualization techniques, term weights, and implications for automatic indexing in information retrieval systems.…
