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)

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…

Describes the computerized film documentation system being developed for use in the Film Archives of the Netherlands Information Service. The organization of the films by historical periods, the film access system, content analysis of the films, and operation of the film retrieval system are discussed. Four figures accompany the text.

A proposed cataloging and information access tool for children's media would combine the most useful aspects of library subject-heading lists and thesauri to meet American Library Association recommendations for subject cataloging of juvenile material. Computer-based production of a preliminary edition is planned for 1983. Fifteen references are…

Wiswesser Line Notation, a system for representing structural formulas by a single line of common symbols (numerals, capital letters, and three punctuation marks), is gaining acceptance as an effective indexing tool. The resulting notations, denoting specific structural fragments of a molecule, can be retrieved by humans or computer. (Author/JN)
