This report provides a detailed description of Chips, an interactive tool for developing software employing graphical/computer interfaces on Xerox Lisp machines. It is noted that Chips, which is implemented as a collection of customizable classes, provides the programmer with a rich graphical interface for the creation of rich graphical…

The SIRIUS language is intended for solving both numerical and analytical problems. The new language is realized by means of a two-phase translator. The first phase is a translation into an intermediate (Polish-nonparenthetic) language; the second phase is an interpretation from this language. Two modes of program execution are envisaged in the…

Describes an educational interface designed to allow non-computer oriented authors to design courses for use on the Havering Computer Managed Learning System. (Author/LS)

This report consists of two papers on MENUNIX, an experimental interface to the approximately 300 programs and files available on the Berkeley UNIX 4.0 version of the UNIX operating system. The first paper discusses some of the psychological concerns involved in the design of MENUNIX; the second is a tutorial user manual for MENUNIX, in which the…

The position papers presented at a seminar held in 1969 at Leeds University are the basis of this report. The papers cover the topics of computers in education, learning systems, planning and management, hardware and engineering, development processes in computer assisted instruction (CAI), and economic problems. The 46 participants at the seminar…

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 report, resulting from the Context Information Processing Project, is a review of request language and search logic in its present state with the purpose of relating these findings to the design of QUERY (the language described in LI 001 652) and to context information processing needs. A basic assumption is that an information retrieval…

Proposes extensions to PASCAL that provide for programing man-computer dialogues. An interactive dialogue application program is viewed as a sequence of frames and separate computational steps. PASCAL extensions allow the description of the items of information in each frame and the inclusion of behavior rules specifying the interactive dialogue.…

This first of two related articles by the same authors describes the philosophy, design, and implementation of an experimental translating computer system, CONIT, whose purpose was to investigate techniques for simplifying access to, and operation of, bibliographic retrieval systems. Forty-one references are cited. (FM)

This paper presents a cognitive account of both the advantages and disadvantages of direct manipulation interfaces, i.e., the use of icons to manipulate and interact directly with data rather than writing programs or calling on a set of statistical subroutines. Two underlying phenomena that give rise to the sensation of directness are identified.…

Paper describes a method of analysing information based on theories about the way in which human beings tackle this problem. (Author)

Intended for users of the 3RIP text retrieval database, for retrieval system users with a knowledge of the EURONET Common Command Language (CCL), and for 3RIP system managers, this booklet provides a complete description of the 3RIP retrieval system command language. New functions and recent changes in the 3RIP system are summarized, system…

The phrase "student computer dialogs" refers to interactive sessions between the student and the computer. Rather than using programing languages specifically designed for computer assisted instruction (CAI), existing general purpose languages should be emphasized in the future development of student computer dialogs, as the power and…

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…

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…
