This paper is concerned with providing automatically generated online explanations to the user of a user interface or "tool" about what the interface can and cannot do, and what parameters or options are available or required with a given command. The COUSIN interface system, developed at Carnegie-Mellon, supplies a cooperative…

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…

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…

Describes two BASIC computer programs to elicit and analyze grids easily and clearly. FOCUS uses a two-way cluster analytic method to re-order the constructs and the elements, and to highlight similarities and differences in the grid. PEGASUS is an interactive program which conversationally elicits a grid, and processes and offers real-time…

This paper describes a system which operates on an independent basis as well as connected to communications network, e.g., PLATO and ASCII based communication systems. The system also has facilities for local production and use of PILOT lessons, for support of a generalized programming language (NSBASIC), and for development of graphic sequences.…

FRED (a Front End for Databases) was conceived to alleviate data access difficulties posed by the heterogeneous nature of online databases. A hardware/software layer interposed between users and databases, it consists of three subsystems: user-interface, database-interface, and knowledge base. Architectural alternatives for this database machine…

Describes the features and operations of a user-searchable online catalog called PaperChase which was developed and implemented for the retrieval of medical literature by physicians at Beth Israel Hospital in Boston. Interaction with the system and use of the catalog during its first year of operation are discussed. (JL)

This report describes the development of computer programs called user agents, which, through interaction with users, can either learn new facts and store them in a data base or learn new procedures for data manipulation and represent them as programs. These programs are written in RITA, the Rule-directed Interactive Transaction Agent system, and…

This paper describes the construction and implementation of an autoprogramming system. An autoprogrammer is an interactive computer programming system which automatically constructs computer programs from example computations executed by the user. The example calculations are done in a scratch pad fashion at a computer display, and the system…

Reports on the development of the Individualized Instruction for Data Access System (IIDA), a computer system designed at Drexel University, which serves as an intermediary enabling users to perform complex tasks on another computer. Capabilities of the instruction mode and assistance mode are discussed. Fifteen references are cited. (EJS)

Describes an interactive data retrieval system which was designed and implemented for casual users and which incorporates a user-friendly interface, aids to train beginners in use of the system, versatility in output, and error recovery protocols. A 14-item reference list and two figures illustrating system operation and output are included. (JL)

Discusses intelligent front-end processors designed to impose uniform standards on multiple databases and assist searchers, including motivation for development, prototypes from research community, commercial systems using microcomputers, capabilities and problems encountered in developing Franklin Institute's Online Database Search Assistance…

This paper reviews the current extent of, research into, and future expectations for the use of online bibliographic retrieval systems by untrained end users rather than by trained search intermediaries. Six sections cover: (1) studies of direct end user searching, done primarily with students or persons in highly technical fields; (2) problems to…

People use a variety of plausible, but uncertain inferences to answer questions about which their knowledge is incomplete. Such inferential thinking and reasoning is being incorporated into the SCHOLAR computer-assisted instruction (CAI) system. Socratic tutorial techniques in CAI systems such as SCHOLAR are described, and examples of their…

Provides a step-by-step guide to creating an interactive video program, using technology that allows a computer program to control a video program, and discusses the concept, the equipment (microcomputer, videoplayer, and video interface card), and the process involved. A buyer's guide to video interface cards is included. (EJS)
