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)

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)

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)

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)…

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.…

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. (22 references) (Author/SJ)

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)

The development of scientific journals in Japan pertinent to chemistry is reviewed, and the current status of abstracting activities in Japan is described. (Author)

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)

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)

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)

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…

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)

Scientists and engineers have solved their wordage and most other information problems through the creation and use of information analysis centers (IAC). IAC's synthesize, analyze, and compress pertinent information so that knowledge transfer remains effective. (Author/NH)
