A low-cost automatic classification method is reported that uses computer time in proportion to NlogN, where N is the number of information items and the base is a parameter, some barriers besides cost are treated briefly in the opening section, including types of intellectual resistance to the idea of doing classification by content-word…

This report describes a quantitative study of subject-indexing as it is being performed by catalogers who are developing an augmented catalog as part of Project Intrex. Learning curves for the average time taken to index technical documents on a per-page basis were derived for a group of indexers. The average indexing times per page were also…

This report presents a procedure for compiling a typed index using a DECsystem 10 computer without index cards, with the following objectives: (1) to increase compilation speed of a typed index; (2) to provide a machine-readable version of an index that can be edited rapidly; (3) to provide two forms of an index--one arranged by page number to…

The "CumIndex" cumulates the back-of-book indexes of 96 English-language works in the field of library and information science and thus provides an in-depth index to important works in the field. The list is the result of a sequence of computer programs which edit, modify, and reorganize index entries from individual books to provide a coherent…

The English-language literature since 1950 was searched to gather published reports of abstracting and indexing rates and costs, and cost figures for the complete preparation of secondary publication. The search located relevant information by 24 abstract journals and 3 citation services, 18 abstracting cost figures, and 41 indexing cost figures.…

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…

In order to contribute to the success of several studies for automatic classification, indexing and extracting currently in progress, as well as to further the theoretical and practical understanding of textual item distributions, the development of a frequency program capable of supplying these types of information was undertaken. The program…

Progress is reported on the development of a partial syntactic analysis technique for indexing text. Although over 500,000 words of text have been indexed, this report is limited to the analysis of results at the 115,000 word level. There is the expectation that the error rate of commission, the selection of grammatically incorrect word sequences,…

The report is the result of a study of the language of information science based on the terminology contained in a collected set of lexical resources. The terms employed were taken from vocabularies having a substantial degree of overlap. All terms were then analyzed to build a composite vocabulary of terms and concepts using a set of twenty-five…

The Project Grant Information System (PGIS) is a computerized information indexing and retrieval system which supports the U.S. Office of Education. Its purpose is to provide OE officials with up-to-date information about the Office's discretionary grant programs and projects. The purpose of the Taxonomy is to provide: (1) those individuals who…

Methods of automatically generating controlled subject headings and classifications from free indexing in the INSPEC data base were evaluated. (PF)

This brief review of the documentation activities of the United Nations Library at Geneva includes a general description, documentation activities (current bibliographic publications, specialized bibliographies and reference lists), catalog card service, major documents, indexing of official documents originating in the UN, technical tools used,…

Gedenken experimentation provides a theoretical basis for what the indexer does, lends itself to (1) various schemes for the education of indexers, (2) the provision of graphic aids to indexing, and (3) the evaluation of indexing performance. Traditional solutions to the indexing problem are also discussed and compared with the gedanken method.…

Explains the function and operation of the Chemical Registry System operated by Chemical Abstracts Service (CAS). (CP)

Examines statistical techniques for exploiting relevance information to weight search terms. These techniques are presented as a natural extension of weighting methods using information about the distribution of index terms in documents in general. (Author)
