This document reports on a study that explored the feasibility of using New York State Education Department data to develop multiple regression equations required for simulating the effects of alternative expenditure configurations on pupil achievement. Specific study objectives were: (1) to test the effectiveness of factor analysis as a procedure…

Investigated were the attitudes of basic biological researchers toward information systems currently used, the usefulness of these services in meeting information needs, and the services expected from an advanced information system. A sample of 50 biological researchers from 14 academic institutions representing 19 areas of specialization was…

This report describes digital computer simulation efforts in a study of memory systems for two important cases: that of the individual the brain; and that of society, the library. A neural system model is presented in which a complex system is produced by connecting simple hypothetical neurons whose states change under application of a…

This document is a study of the processing of questions input to computerized question-answering system such as the RAND Relational Data File. The process consists of (1)transforming the natural-language question into a symbolic question (i.e., a certain formula of predicate calculus) and (2)generating the answer by calculating the value set of…

In 1968, the Western Interstate Commission for Higher Education (WICHE) initiated a 5-year management information systems project to encourage systematic data collection and utilization for the effective allocation of resources at institutions of higher education. This report describes Phase II of the project, a developmental phase scheduled for…

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,…

This thesis describes a character generator which was built for a refreshed cathode-ray tube (CRT) display and demonstrates the feasibility of displaying high quality dot-matrix characters using the low-band width sinusoidal scan. The CRT used was a low-cost entertainment-quality television tube, and hence had a very poor deflection band width.…

This is the second in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form. It consists of two parts. The first part defines the basic interaction alternatives and subalternatives open to the NAL with respect to its interfacing…

Sixth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine-readable form, this report deals with the query language, search strategy and related considerations for a particular information storage and retrieval system. One section of the…

The SDI system now operational at the Institute for Atomic Research, Iowa State University, is implemented with the concept of feedback. The profile user is notified of a document which may be of interest to him and indicates his response to this document on the response card accompanying the notification. The profile words carry individual…

A resume of the Ames Laboratory Selective Dissemination of Information (SDI) Computer System is presented. The results of three types of evaluation studies made of the Ames Laboratory SDI systems are discussed which include: evaluation of model studies utilizing restricted document and user sample sizes; statistical evaluation of production runs…

Oral Roberts University opened in 1965 with an audiovisual Dial Access Information Retrieval System designed to provide basic course information to students. After the novelty and problems of the start, the system has progressed to the point where over half of the general education course work is now offered by the systems approach--creating a…

Organizations which are currently providing computerized searches of the ERIC data base are listed and briefly described. For each of the over 120 sources of computer searches identifies in the document the following information is listed: name and complete address, population served, files available, how to submit an inquiry, form of search…

ERIC (Educational Resources Information Center) was the first attempt to develop a systematic way of collecting, storing, organizing, disseminating, and analysing information in the field of education. ERIC operates at four levels. At the top is the governmental level office, central ERIC, which supervises the ERIC Processing and Reference…

This paper on Thesauri in Educational Documentation attempts to show by description and analysis the difference in application between thesauri and classification schemes as indexing languages in documentary information systems, and from this to infer possible future developments. First, the differences between the pre-coordination and…
