Chemical structure diagrams are considered as utterances in a written language. Two types of grammars are considered for this language: topological grammars and geometric grammars. The hypothesis is presented that compact computer storage may become accessible via grammars. (15 references) (Author/NH)

A tutorial introduction to data models in general is provided, with particular emphasis on the relational and network models defined by the two proposed ANSI (American National Standards Institute) database language standards. Examples based on the network and relational models include specific syntax and semantics, while examples from the other…

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

The computer language FOL is intended to facilitate the implementation of file organizations for information storage and retrieval systems. In many information storage and retrieval applications the designer, initially, does not know how best to organize a data base for efficient retrieval and ease of updating and modifying. It is felt that FOL…

The document retrieval system at Coordinated Science Laboratory is implemented on a Control Data 1604 computer system. Recorded information from each source article includes 1) conventional bibliographic data such as authorship, author affiliation, title, year of publication, etc., 2) detailed bibliographic data from each of the cited references,…

Recognizing that the use of resource sharing capabilities provided by computer networks is inhibited by the requirement that the user become familiar with the varied command languages and protocols of each accessed system, this report presents a general approach to solving the problem using an intermediary system to support a set of common…

INFOL for the CDC 6400 is a rewrite in FORTRAN IV of the CDC 3600/3800 INFOL (Information Oriented Language), a generalized information storage and retrieval system developed by the Control Data Corporation for the CDC 3600/3800 computer. With INFOL, selected pieces of information are extracted from a file and presented to the user quickly and…

The design of an English-like query language and an interactive computer environment for searching the full text of the U.S. patent collection are discussed. Special attention is paid to achieving a transparent user interface, to providing extremely broad search capabilities (including nested substitution classes, Kleene star events, and domain…

The Information Sciences section of ITT Research Institute (IITRI) has developed a Computer Search Center and is currently conducting a research project to explore computer searching of a variety of machine-readable data bases. The Center provides Selective Dissemination of Information services to academic, industrial and research organizations…

Information based on courses and seminars held at the Second International Summer School on the elaboration of linguistic and literary fundamentals, Pisa, Italy, September 1972; paper presented at the Second International Conference on Linguistics and Translation, October 4-7, 1972, Montreal, Canada.

This annual report of the Department of Computer and Information Science at Ohio State University for July 1977-June 1978 covers the department's organizational structure, objectives, highlights of department activities (such as grants and faculty appointments), instructional programs/course offerings, and facilities. In the second half of the…

A videodisc system provides a means of storing substantial volumes of pictorial information. Individual pictures and sequences of images may be accessed directly thereby providing many novel approaches to image retrieval and display. When combined with an interactive computer system, a videodisc is able to create a useful tool to aid the…

This paper documents the program used in the application of the INFO system for data storage and retrieval in schools, from the viewpoints of both the unsophisticated user and the experienced programmer interested in using the INFO system or modifying it for use within an existing school's computer system. The opening user's guide presents simple…

The 13 papers collected here were presented at the Workshop on Data Documentation held at Reisenburg Castle, Federal Republic of Germany, in July 1975. This workshop was a first attempt to identify some of the problems in the field of data documentation, formulate them, and solve them as far as possible. The subject was approached from four…

The Bibliographic Service Development Program of the Council on Library Resources convened a meeting of experts in March 1984 to consider the advisability of applying standards in the development and operation of online public access catalog systems in libraries. Following presentations from three invited participants, working groups were formed…
