Pepinsky, Harold B. – Journal of the American Society for Information Science, 1974
A rationale for constructing a metalanguage to analyze natural language texts is provided in the context of a long-range program of research, and illustrated by reference to an existing Computer-Assisted Language Analysis System (CALAS). (JB)

Romanec, Michael J. – Journal of Chemical Documentation, 1974
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)

Feldman, Alfred – Journal of Chemical Documentation, 1973
A Teletype Model 37 machine has been modified for the coding of chemical structures. The coding rate of this model is higher than that of other machines of this type. The rationale for choosing this particupar type of input equipment is presented. (6 references) (Author/SM)

Kiehlmann, Eberhard – Journal of Chemical Documentation, 1973
Science Citation Index'' and several new Chemical Abstracts''' indexes are discussed as effective tools for retrospective literature work and a comparison is made of the features of Chemischer Informationsdienst,'' Index Chemicus,'' Chemical Titles,'' and Current Contents'' as the main sources of current chemical information. (9 references)…

Wilson, Patrick – Information Storage and Retrieval, 1973
Situationally relevant items of information are those that answer, or logically help to answer, questions of concern. Significant situationally relevant information is explained in terms of changes of view in relation to questions of concern. It is claimed that situational relevance is an explication of the ordinary notion of practical relevance.…

Klingbiel, Paul H. – Information Storage and Retrieval, 1973
To index at the Defense Documentation Center (DDC), an automated system must choose single words or phrases rapidly and economically. Automation of DDC's indexing has been machine-aided from its inception. A machine-aided indexing system is described that indexes one million words of text per hour of CPU time.

Wingate, Henry W. – Library Resources and Technical Services, 1972
The Cataloging-in-Publication program faces a number of difficult problems. The difficulties that resulted in the failure of the 1958-59 Cataloging-in-Source program still exist, and the actual value of such a project to libraries has yet to be proved. (26 references) (Author/SJ)

Hirayama, Kenzo – Journal of Chemical Documentation, 1973
The development of scientific journals in Japan pertinent to chemistry is reviewed, and the current status of abstracting activities in Japan is described. (Author)

Salton, G. – Journal of the American Society for Information Science, 1972
A new testing process is described. The design of the test procedure is covered in detail, and the several language processing features incorporated into the SMART system are individually evaluated. (20 references) (Author)
Descriptors: Automatic Indexing, Comparative Testing, Indexing, Information Processing

Nunn, G. Raymond – Library Quarterly, 1971
To expand the present inadequate range of controls, reprinting and microfilming of existing indexes, catalogs, and inventories are proposed. The role of automation for control of research resources, including retrospective as well as current materials, is described. (109 references) (Author/NH)
Descriptors: Archives, Automation, Bibliographies, Documentation

Helmuth, Nancy A. – Journal of the American Society for Information Science, 1971
The use of extracts as a substitute for abstracts in information services is explored via a survey and a literature review and guidelines for selecting extract material from documents are given. (30 references) (NH)

Smith, Kingsley R.; Judy, Theodore M. – Journal of the American Society for Information Science, 1972
An operational, comprehensive, economical method for updating and correcting entries in a computerized bibliographic system is presented. The technique was developed in connection with the East African Agricultural Bibliographic Project at West Virginia University. Data modification operations are discussed as well as the limitations of the method…

Gilchrist, Alan – Journal of Documentation, 1972
A general account is given of the problems, the work of the DOE, the existing schemes; and proposals are put forward for the compilation of a metasystem'' which would be used to control or steer the conventions used for information handling. (27 references) (Author/NH)
