After consideration of two recent examples of instruction sets for microprogramable computers, the article sketches known and new results about complete sets of functions which appear to be applicable to microlanguage development. Some needed areas of research are pointed out. Functional completeness is linked to research in control primitives for…

The development and testing of the Browsing On-line With Selective Retrieval (BROWSER) text retrieval system allowing a natural language query statement and providing on-line browsing capabilities through an IBM 2260 display terminal is described. The prototype system contains data bases of 25,000 German language patent abstracts, 9,000 English…

Several algorithms were investigated which would allow a user to interact with an automatic document retrieval system by requesting relevance judgments on selected sets of documents. Two viewpoints were taken in evaluation. One measured the movement of queries toward the optimum query as defined by Rocchio; the other measured the retrieval…

Part A contains general comments on various aspects of computer science education, particularly that for the mass. Part B describes some of the concrete examples carried out successfully. (Author)

This introduction to computers might be used by readers as young as the middle school. It includes elementary explanations of these topics: history of computers, what computers can and cannot accomplish, how computers work, what flowcharts are, and how programs are written. Interspersed with explanations are simple problems which ask readers to…

This study has investigated some pattern recognition capabilities of devices consisting of arrays of cooperating elements acting in parallel. The problem of recognizing straight lines in general position on the quadratic lattice has been completely solved by applying parallel acting algorithms to a special code for lines on the lattice. The…

This document explains A Programming Language (APL) and describes the experiment that the Information Processing Division has undertaken to introduce APL to the Goddard Scientific Community. A brief historical sketch of steps taken to date is included and appendices giving illustrative examples of how APL actually has been used at the Goddard…

Magnetic tape format specifications for authority records distributed by the Library of Congress through the MARC Distribution Service--Subject and Name Authorities are described in this outline. Information is provided on segments and length of logical records, blocks, volume and file organization, and character set. (KP)

Extensions are required to the currently operational INGRES data base system for it to manage a data base distributed over multiple machines in a computer network running the UNIX operating system. Three possible user views include: (1) each relation in a unique machine, (2) a user interaction with the data base which can only span relations at a…

This paper describes the methodology of a project to develop a computer program capable of reading casually hand-printed FORTRAN programs. (Author)

Author contends that the future of computer assisted instruction lies in the wealth of concepts, analytical tools and practical techniques which computer scientists have accumulated in the process of learning to build and program various kinds of systems and hardware. (Author/HB)

Temple and Pepperdine Universities have found it profitable to contract out developing a plan for new computer facilities, equipment, systems, and staff to meet the needs and goals of the institutions. (Author/MLF)

This article explores ways in which library and computing scientists can cooperate to serve social science users by blending the unique talents and traditions that each has to offer. (Author)

In describing two examples of students asked to write programs to solve problems, a serious defect in training is illustrated with potentially important consequences for students and employers. (Author)
