Three firms which offer online information retrieval are compared. The firms are Lockheed Information Service, System Development Corporation and the Western Research Application Center. Comparison tables provide information such as hours accessible, coverage, file update, search elements and cost figures for 15 data bases. In addition, general…

The information retrieval demonstration and research project was designed to demonstrate the computer terminal system of information retrieval from a central computer. Specifically, the system concentrated on computer searching of the ERIC system. The demonstrations took place by locating nine terminals in volunteer districts and conducting…

This reported research centered on development of the concept of a translating computer interface by which the networking of heterogeneous interactive information systems may be achieved during the period in which information retrieval system and network standards are evolving. The particular concepts and techniques investigated are the virtual…

Parallel machine and manual literature searches on the subject of chemical evolution and the origin of life were compared on six characteristics: (1) precision, (2) recall, (3) novelty, (4) uniqueness, (5) time cost per citation, and (6) dollar cost per citation. The manual search outperformed the machine on precision, novelty, uniqueness, and…

Presented is a guide to identifying and using the agencies and organizations that provide information resources relevant to recreation, physical education, and related areas for impaired, disabled, and handicapped persons. Resources listed in the guide are of two types: information systems and compiled sources. Information systems listed are…

Human individuals, social organizations and societies are alike in that their knowledge of past events is to some extent maintained and brought to bear on their behavior. On the individual level we know quite a bit of how this is accomplished. However, on the social level we know close to nothing. It is not the task of this paper to ascertain the…

A user-oriented computer-based information retrieval system which would not require a computer specialist as an interface between computer and user was developed. The PLATO system was chosen because it was a high-speed computer-based man-machine interaction system with convenient visual display, keyset input device, versatile programing…

The research represents an attempt to evaluate information seeking under conditions relevant to the design of information systems and the training of information analysis. The research effort has as its goal the accomplishment of two major experiments. One which has been completed was designed to assess the effects upon information-seeking and…

The paper reports on a series of programs that have been developed at the Moore School to process data-bases, consisting of textual items, and to index and arrange the data items in accordance with an automatically generated classification system. The programs produce the directories and the rearranged data-base on microfilm, where it may be…

The existing volume and increasing growth rate of documented information has resulted in numerous efforts to construct operational Document Storage and Retrieval Systems, as a practical solution to the demand for information storage and retrieval. Accompanying the surge to build more and better and bigger Document Retrieval Systems (DRSs), was the…

Least cost decision rules for transferring documents from primary to secondary storage are developed from a dynamic programing model of an information system. The program is constrained to provide for a minimum acceptable level of user benefits. Knowledge of the physical size of the primary storage area and the fraction of documents returned from…

An investigation was made of the Universal Decimal Classification (UDC) as an indexing language for computer retrieval. Problem areas were identified (notation, schedules, application), new developments reviewed (combining precedence devices, subject analysis matrices, guidelines for schedule revision, pilot schedules, parenthesis-free notation…

This paper is a survey of some of the major semantic models that have been developed for automated semantic analysis of natural language. Current approaches to semantic analysis and logical interference are based mainly on models of human cognitive processes such as Quillian's semantic memory, Simmon's Protosynthex III and others. All existing…

The materials of a library, exemplified by books, have traditionally been viewed as presenting two aspects involving two distinct problems: their description and control as unique items, and their treatment as sources of information on various subjects. But this view has tended to overlook a third fundamental aspect: that of the "works" which are…

This report presents an analysis of the problem of descriptive cataloging as a whole: the aspects of the problem, the questions they raise, the issues involved, the course adopted in the new "Anglo-American Cataloging Rules," and the principles that would serve best the objectives of the catalog.
