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)

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.
