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)

Requests to the National Center for Education Statistics (NCES) for postsecondary education data were analyzed and compared to previously identified issues. Summaries of telephone requests (log entries) and files of letter requests from January 1977 through December 1977 were studied. A single coding scheme was developed for both letter and phone…

Continuing technological advances in computers and communications make possible the integration of data systems and the exchange of data among them on an expanding scale. However, the full effect of these advances cannot be realized unless the need for uniform understanding of the common information (data elements) and their expression in data…

The use of computer technology for the storage and rapid retrieval of information about instructional media requires the development of nationally accepted guidelines or standards for catalog information and computer input. The Department of Audiovisual Instruction (DAVI) organized a task force to develop standards for cataloging educational media…

The compilation of a dictionary for automatic translation from Russian to English is described in detail. Emphasis is placed on: (1) morphological and functional classifications of Russian words, (2) dictionary compilation, (3) the structure of signs, (4) automatic information-processing machines, (5) from the automatic dictionary to the automatic…
