Discusses the role of certain types of classifications in a modern automated environment. (Author/PF)

The Text-Pac System is capable of generating indexes and bulletins to provide a current information service without the selectivity feature. Indexes of the accumulated data base may also be used as a basis for manual retrospective searching. The manual search involves searching computer-prepared indexes from a machine readable data base produced…

Documentation centers are needed to handle the vast amount of scientific and technical information currently being issued. Such centers should be concerned both with handling inquiries in a particular field and with producing a general catalog of current information. Automatic analysis of texts by computers will be the best way to handle material,…

A report on the Ames SDI-KWOK Index (Selective Dissemination of Information--Key Word Out of Context), a computerized information system designed to notify each user of documents of interest, with the help of the descriptors he provides on his user profile. (LS)

The process of initiating and negotiating a literature search in the Educational Resources Information Center (ERIC) data base is discussed in laymen's terms. The guide offers suggestions on choosing a data base, deciding whether to use computerized or manual retrieval, defining the search problem, and understanding the Boolean search strategy…

Surveys the current state of minicomputer-operated information systems capable of incorporating linguistic features, focusing on the Minicomputer Operated Retrieval (Partially Heuristic) System. Consideration is given to the automation of the indexing process and to available search strategies. (FM)

THE REPORT PRESENTS A SUMMARY OF THE DEVELOPMENT AND THE CHARACTERISTICS OF THE FIRST GENERATION OF THE AUTOMATED LITERATURE PROCESSING, HANDLING AND ANALYSIS (ALPHA-1) SYSTEM. DESCRIPTIONS OF THE COMPUTER TECHNOLOGY OF ALPHA-1 AND THE USE OF THIS AUTOMATED LIBRARY TECHNIQUE ARE PRESENTED. EACH OF THE SUBSYSTEMS AND MODULES NOW IN OPERATION ARE…

Against a background of widespread interest in national information systems, the American Institute of Physics is developing such a system for physics. This program pivots on the design of a new classification system for physics which is to be used, in conjunction with free-language index terms, for the intellectual organization of the physics…

Twelve papers written by fifteen authors from nine countries comprise this collection which embraces many of the crucial problems facing modern information science and scientific information activities, ranging from information needs of scientists and specialists to the specific aspects of computerization of various information processes. The…

Introduced are methods for computation of term-term association factors, indexing, assignment of term-document relevance values, and computation for recall and relevance. Recall and relevance are based on quantitative intenal system computations, and results are compared with user evaluations. (Author/MF)

This report discusses the problem of the meansings of words used in information retrieval systems, and shows how semantic tools can aid in the communication which takes place between indexers and searchers via index terms. After treating the differing use of semantic tools in different types of systems, two tools (classification tables and…

Project Intrex is a program of experiments intended to provide a foundation for the design of future information transfer systems, with the library of the future visualized as a computer-managed communications network. In order to discover the necessary facts, especially in the area of the user's interaction with the system, experimentation is…

A set of twenty five questions was processed against a computer-stored file of 9159 document references in the field of ferrous metallurgy, representing the 1965 coverage of the Iron and Steel Institute (London) information service. A basis for evaluation of system performance characteristics and analysis of system failures was provided by using…

The purpose of this document is to present a final description of the original MEDLARS system as it evolved through four years of operation. The system is described as it was functioning on January 1, 1968. Among the various system elements discussed are: (1) the input subsystem, including journal selection and coverage, Medical Subject Headings…

This report describes the current status of Project INTREX experiments and provides a detailed technical record. Activities concentrating on the bibliographic access problem involve: (1) the investigation of a digitally-encoded, machine-manipulated augmented catalog, for which the task of preparing entries for 10,000 documents is about half…
