Considered the problems of excessive accumulation of records, designed to assist schools in evaluating students, which ultimately invade the privacy of individuals. (RK)

An archive of still images in videodisc format becomes a powerful instructional tool when complemented by a computer data base system for selection and retrieval and programs to generate materials and manage image presentation. Considerations in using this potential include database design, a classification system, and computer-videodisc…

Outlines the important factors to be considered in selecting a database management system for use with a microcomputer and presents a series of guidelines for developing a database. General procedures, report generation, data manipulation, information storage, word processing, data entry, database indexes, and relational databases are among the…

A generalized file-conversion program suite for the EUDISED (European Documentation and Information System for Education) information network, suitable for running on a wide range of mainframe computers, is suggested and described. Time and expenditures required to implement the system are assessed. Two other possible methods of handling the data…

This report describes work concerned with the statistical evaluation of the output of MEDICO automatic indexing procedure. The statistical tests were designed to examine the validity of the assumptions which formed the bases of the indexing algorithms with primary emphasis on the algorithm development for the computation of weights and links. Some…

A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional…

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…

The broad objective of this investigation was to explore the potential and applicability of automatic methods for the indexing of drug-related information appearing in English natural language text and to find out what can be learned about automatic indexing in general from the experience. More specific objectives were the development,…

The computational complexity of a formal process for the construction of term classes for information retrieval is examined. While the process is proven to be difficult computationally, heuristic methods are applied. Experimental results are obtained to illustrate the maximum possible improvement in system performance of retrieval using the formal…

The report describes Wisconsin's information retrieval system with remote, on-line computer access to nearly 200,000 educational documents. Briefly outlined are the operations and indexing of materials for the computer program, documents of the Educational Resources Information Center (ERIC), file access, training sessions, and remote location…

Heavy emphasis was placed on experiments, and interpretation of experimental results. A set of experiments was designed to yield quantitative information on how the experimental subjects used the full-text-access system, why they used it and how effective it was. A detailed report of work on this topic to date is presented. The in-depth analysis…

Describes a system to improve the efficiency and understanding of the educational programs students pursue. Offers a complete summary report on status of students in the program and future course requirements. The system decreases counseling time. (Author/TS)

Computer simulations can be used in social studies to analyze problems by using a representation or model of a situation and then exercising the model to see how it behaves under different circumstances. Utilizing available computer programs, students can also build and use social studies data bases. (RM)

IF COMPUTER PROGRAMS ARE TO SERVE AS USEFUL MODELS OF COGNITIVE BEHAVIOR, THEIR CREATORS MUST FACE THE NEED TO ESTABLISH AN INTERNAL ORGANIZATION FOR THEIR MODEL WHICH IMPLEMENTS THE HIGHER LEVEL COGNITIVE BEHAVIORS ASSOCIATED WITH THE HUMAN CAPACITY FOR SELF-DIRECTION, AUTOCRITICISM, AND ADAPTATION. PRESENT COMPUTER MODELS OF COGNITIVE BEHAVIOR…

This report describes Phase 1 of a research project with the over-all objective of exploring the applicability of automatic methods in the indexing of drug information appearing in English natural language text. Two major phases of the research have been completed: (1) development of the automatic indexing method and its implementation on the test…
