The extent to which all three or any two of the services under study select the same journal article for coverage, as determined by examining each service's selection records for those journals found to overlap, is analyzed. (2 references) (Author/KE)

Two statistical models for estimating search time have been developed for the CA Condensates data base using the University of Georgia Text Search System. Comparative timings between the Chemical Abstracts Service search program and the University of Georgia search program are made for the Ca Condensates data base. (5 references) (Author/NH)

Broad coverage is essential to the effectiveness of information services. This paper criticizes the misleading claims made regarding computer-based systems in this context. It describes the Scientific Documentation Centre's services, the basis on which its resources are allocated, and the criteria for selection of operating techniques and…

A straightforward procedure for performing weighted-term searches can be programmed quickly and easily, and the same general algorithm can be used for either on-line or batch mode searching. The method can be used to do whole text searches as well as conventional searches for index terms or other descriptors. (5 references) (Author/NH)

Mechanization has been introduced in the preparation of UDC and alphabetical indexes using a KWIC Program to access directly documentation files. A special feature of the system is that the KWIC serial number equals the program sorting number equals the encoded UDC form equals the storage or shelving number. (9 references) (Author/NH)

This experiment was an attempt to extend recent findings by examining how contextual changes might produce variations in the correct recognition of verbal units' previously presented in a compound display. (Authors/CB)

This study is consistent with a model of semantic memory that assumes that the memory store is organized primarily into noun categories, and that the process of retrieving information from this store consists of entering the appropriate category as a first step. (Authors)

A model computer-assisted information retrieval system was developed to explore techniques for electronic searching of music education data. The list of concepts was collected from existing indexing services, including the Music Index, Reader's Guide to Periodical Literature and the Thesaurus of ERIC Descriptors. (Authors/CB)

The incentive and the main lines of French policy on chemical information, as well as their implementations, are described. The DARC (Description, Acquisition, Retrieval, Correlation) system is being implemented as a tool of national policy for chemical information. (21 references) (Author/NH)

It was concluded that the retrieval of information from immediate memory is dependent upon the degree of rehearsal of presented information. (Author)

This review of the Keyword-in-Context (KWIC) indexing considers its inception by Luhn, its original format and purpose, various applications and uses of the basic KWIC concept, its advantages and disadvantages, and evaluations of its effectiveness. (30 references) (Author/NH)
