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.

A pilot information retrieval and dissemination unit was established within the South Carolina Department of Education in July, 1970. A major goal was to develop an effective and efficient link between information sources and educators utilizing interpersonal communication linkages. Improvement of state and local educational practices was the main…

This revised directory of the information sources in the DDC Referral Data Bank (previously issued in October 1970 as AD-712 800 and in July 1971 as AD-724 700) consists of a compilation of computer printouts, each of which gives for a single activity detailed descriptive information on the mission, scope and services provided. Arrangement is by…

This report provides a complete and up-to-date review of the abstracting and indexing services available in water resources engineering. Between 1955 and 1970 the number of services in this field increased from about 20 to 40. This exponential growth or doubling every 15 years suggests that by 1985 there will be 80 abstracting services in…

WISE-ONE, an information retrieval system, was designed to facilitate searches of the documents cataloged by the ERIC centers and distributed as ERIC RESUMAST master files. WISE-ONE is written to search for documents cataloged under any of the three indices (descriptors, identifiers, and author name), called search keys, and will yield the ERIC…

PROBE, a search and retrieval program, was developed in 1970 at Indiana University to search the computer tape bases for the two ERIC publications, "Research in Education" (RIE) and "Current Index to Journals in Education" (CIJE). The ERIC tapes are received, converted, and combined at the University and implemented on the…
