A series of five batches of twenty searches were carried out in a three year span of the INSPEC data base by the 31 Company's Information Retrieval Service. The same queries were processed manually in the corresponding volumes of Science Abstracts and comparison of the output of each search method exposed reasons for the failures. Emphasis is laid…

Presented is an exploration of parallel processing as it might be applied to three functions fundamental to information science: sorting, searching, and evaluation of a search prescription. (Author)

The goal of this project was to find ways of enhancing the efficiency of searching machine readable data bases. Ways are sought to transfer to the computer some of the tasks that are normally performed by the user, i.e., to further automate information retrieval. Four experiments were conducted to test the feasibility of a sequential processing…

The application description is directed to those desiring to acquaint themselves with the characteristics of the General Information Processing System (GIPSY). It provides guidelines and aids for the preparation and use of the system, and covers such areas as: (1) Information Collection and Creation, (2) Information Retrieval, (3) Maintenance…

The boundary between two neighboring rings is called the fusion lines, which is enclosed by external segments called arcs. In the code, the separation of fusion line(s) from arcs takes place in such a way that proper matching is achieved. By this procedure, the structure of a compound is recreated. (Author)

The new data retrieval system for the social sciences which has recently been installed in the UNESCO Secretariat in Paris is described in this comprehensive report. The computerized system is designed to facilitate the existing storage systems in the circulation of information, data retrieval, and indexing services. Basically, this report…

Librarians must become skilled in the language and techniques of computer systems and data management in order to administer large machine readable files of information. An annotated bibliography for a self-education program is appended. (Author/AB)

The computer system described was developed as a departmental aid in locating documents for use as teaching material or for research purposes in the area of information science. The data base of about 2,000 records includes a departmental library of manuals, reports, technical literature, and reprints, as well as journal references and book…

Briefly described is the County of San Mateo Online System (COSMOS) which was developed and is used by the San Mateo Educational Resources Center (SMERC) to access the Educational Resources Information Center (ERIC) and Fugitive Information Data Organizer (FIDO) databases as well as the curriculum guides housed at SMERC.

Proper name matching schemes are reviewed and an updated version of these schemes is tested on a suburban telephone book. (Author/AB)

Batch mode processing is compared, using cost-effectiveness, with on-line processing for computer-aided searching of chemical abstracts. Consideration for time, need, coverage, and adaptability are found to be the criteria by which a searcher selects a method, and sometimes both methods are used. There is a tradeoff between batch mode's slower…

A series of five runs comprised of 20 searches each were carried out in a three-year span of the INSPEC data base. The same queries were processed manually in the corresponding volumes of Science Abstracts, and comparison of the output of each search method exposed reasons for the failures. Emphasis is laid on the fact that a query comprises other…

The unclassified and unlimited bibliography compiles references dealing specifically with the role of computers in information sciences. The volume contains 239 annotated references grouped under three major headings: Artificial and Programming Languages, Computer Processing of Analog Data, and Computer Processing of Digital Data. The references…

Problems encountered in converting a card-oriented biological data information system to new computer equipment are discussed. Data formats, input-output procedures, search strategies, etc., are described. (5 references) (Author/SJ)
