The currently operational version of the INGRES data base management system gives a relational view of data, supports two high level, non-procedural data sublanguages, and runs as a collection of user processes on top of a UNIX operating system. The authors stress the design decisions and tradeoffs in relation to (1) structuring the system into…

The history of computer-assisted instruction (CAI) courseware is described with specific reference to the PLATO system. Among the goals of courseware authors are finding better ways to develop the cognitive skills of students, to shift some of the burden of routine classroom instruction away from the teacher so that more class time can be spent in…

In order to show that a new type of programing for computer assisted instruction (CAI) is feasible, the SCHOLAR system was written. It is information structure oriented, based on the utilization of a symbolic information network of facts, concepts, and procedures. It can generate out of its information network the material to be presented to the…

A recently developed cost-effectiveness model for on-line retrieval systems is discussed through use of an example utilizing performance results collected from several independent sources and cost data derived for a recently completed study for the American Psychological Association. One of the primary attributes of the model rests in its great…

Technique for Establishing Personnel Performance Standards (TEPPS) is a tool for use in man-machine system design and analysis. This is a guide to its application. It specifies the types of input data required, provides instructions and examples on how to proceed through the various steps in TEPPS' application, and includes guidelines for…

The four papers presented at this weekend school are: (1) "The Effect of the Computer on Libraries" by J. D. Dews; (2) "Machines in a Rural Library Service" by O. S. Newman; (3) "The Education of Libraries in an Age of Mechanization" by D. E. Davidson and (4) "People, Programmes and Problems" by B. J. Perry.…

The objective of the current work program is to develop an on-line computer capability that would assist an information analyst in processing textual materials. The initial result of the work program is the design of a system for text processing and a computer implementation of a preliminary model of the system that strongly supports the validity…

This paper reports an experiment in on-line retrieval using man-machine dialogue on a remote console. Message editing procedures and the use of two command languages are described. The system employs a PDP-8 computer for generating, proofreading, and editing messages, and an IBM 7040 computer for information retrieval processing. The symbolic…

Reported are the findings of the Uspekhi experiment in creating a labeled machine file, as well as sample products of this system - an article from a scientific journal and an index page. Production cost tables are presented for the machine file, primary journals, and journal indexes. Comparisons were made between the 1965 predicted costs and the…

Some of the major results of future goals of an automatic program synthesis project are described in the two papers that comprise this document. The first paper gives a detailed algorithm for synthesizing a computer program from a trace of its behavior. Since the algorithm involves a search, the length of time required to do the synthesis of…

Nine job control language (JCL) procedures for the Rapidly Extensible Language (REL) batch system are presented. The REL system itself is a total software system designed to facilitate communication with the computer in very high level languages. Its goal is an interactive time-shared system, but for a variety of reasons it has been desirable to…

Delay of feedback studies with animals or with tasks which are simple for human subjects have led to the common assertion that computer-assisted-instruction (CAI) systems should incorporate immediate feedback in order to maximize learning. However, studies using more complex learning tasks have suggested that delays of up to at least a day…

On the 14th and 15th of January, 1971, a workshop on The User Interface for Interactive Search of Bibliographic Data Bases was held in Palo Alto. The participants were provided in advance with a challenge paper and with a number of papers prepared in response to that challenge. The Workshop sessions themselves were devoted exclusively to focussed…

Discusses the prospects for fully automatic machine translation of good quality. Sections include history and background, operational and experimental machine translation systems of recent years, descriptions of interactive systems and machine-assisted translation, and a general survey of present problems and future possibilities. (VT)

Describes a project to unite visual and audio compositions for simultaneous presentation in multi-media performances. Using a high-level graphics programing language, an applications program was written to the specifications of the composer. Description of the design system and graphics program include discussion of some of the difficulties…
