Describes research designed to improve automatic pre-coordinate term indexing by applying language analysis techniques to identify term sources in requests, and to generate variant expressions of concepts involved for document text searching. Text analysis, term extraction, variant generation, and retrieval trial are highlighted. Thirteen…

This volume is a compilation of the papers presented at the 10th ASIS (American Society for Information Science) workshop on classification research. Major themes include the social and cultural informatics of classification and coding systems, subject access and indexing theory, genre analysis and the agency of documents in the ordering of…

Substantial alterations to a system often have little or no effect on particular collections. This may be due to poor separation of relevant and non-relevant documents. The paper presents a procedure for characterizing this separation, which can show whether proposed modifications of the base system are likely to be useful. (8 references)…

Retrieval performance with automatic term classifications for three test collections has been variable. This paper attempts to discover why. The real difference between the collections is in the separation of relevant from non-relevant documents. The separation is so poor that classification cannot be expected to succeed.

SOLAR is an interactive Storage and On-Line Automatic Retrieval system which is operational at Washington State University. It can run continuously with virtually any mix of tasks in a general purpose computing environment. (22 references) (Author)

A formula is given that enables one to determine the parameters for amortizing an information system within a year. The formula is illustrated with three mechanized information systems for patents. The most critical parameter is shown to be indexing time. (7 references) (Author/NH)

Paper presented at Special Libraries Association Annual Conference (Montreal, June 1969). A survey of 75 special libraries on use of the NASA Thesaurus and Thesaurus of Engineering and Scientific Terms (TEST). The findings reveal wide use and satisfaction with both. (JS)

The relative retrieval efficiency of the title searching technique and the index term searching technique is so close that the choice of one method or the other must be primarily on economic grounds. (9 references) (Author)

Comments are made on several specific questionable aspects of experimental design in the Second Cranfield project." 8 references. (Author)

The experimental results obtained by testing the main hypotheses indicated that there was no difference between the two indexing methods compared, indexing from an alphabetical list alone, and indexing with the suggestion lists as a supplement to the alphabetical list. (Author/MM)

The procedures used to produce the index to volume 20 (1969) of American Documentation are described to demonstrate a system for computer-assisted indexing and bibliographic production developed at the Columbia University School of Library Science. The system is demonstrated to be economic in comparison to currently used manual methods. (Author/MF)

Describes use of the editing language, format commands, and edit commands for General Electric's Remote Access Editing System (RAES) in library applications. (DE)

Results of workshops focusing on the indexing process conducted by Aslib Informatics Group and its predecessor the Co-ordinate Indexing Group are reported, noting seminars held in 1977, 1978, 1980, and 1981. Indexing techniques and subject words chosen for journal articles are appended. (EJS)

Background, construction, and characteristics of a machine translation system developed in Germany and close to implementation are described. Among the characteristics are multilinguality, extendability, flexibility, modularity, and special features such as data structure, interface structure, and lexicon system. The broad range of applications is…
