THE MANUAL DESCRIBES AND DOCUMENTS THE RETRIEVAL SYSTEM IN TERMS OF ITS TAPE AND DISK FILE PROGRAMS AND ITS SEARCH PROGRAMS AS USED BY THE LEHIGH CENTER FOR THE INFORMATION SCIENCES FOR SELECTED CURRENT LITERATURE OF THE INFORMATION SCIENCES, ABOUT 2500 DOCUMENT REFERENCES. THE SYSTEM IS PRESENTLY ON-LINE VIA TELETYPE AND CONVERSION IS IN PROCESS…

Past problems encountered in the use of computers are discussed. They include: (1) computing and data storage costs; (2) machine speed and capacity limitations; and (3) the limited number of languages and Input/Output devices available to facilitate man/machine communication. The improvements in all of these areas are explained. The problems which…

Paper presented at the Second International Conference on Linguistics and Translation, October 4-7, 1972, Montreal, Canada. (DD)

Describes new microcomputer software and hardware which simplify data communications between computer systems. "Dumb" terminal software, programs which enhance a computer's data communications flexibility by means of character translation and data buffering, stand-alone versus integrated systems, and "smart" modems are…

A wide range of computer crimes and the need for computer security are discussed. (MK)

This basic introduction to microcomputers provides the neophyte with the terminology, definitions, and concepts that explain the microcomputer and computing technology in general. Mathematical operations with binary numbers, computer storage, controlling logic, and the concepts of stack and interrupt are explained. (RAO)

This document describes the development of the PLATO system, and six figures illustrate the chronological development of PLATO terminals, lesson programing languages, instructional material, and system usage. A list of financial supporters of PLATO and the Computer-based Educational Research Laboratory is followed by a chronological listing of…

Interactive computers are providing more services to greater numbers of users. However, before such systems can be economically applied to public education, the cost of high performance memory must be reduced. By using massive amounts of serial memory in conjunction with a highly sophisticated memory controller, a system was constructed which…

Reviews computer storage devices designed to provide additional memory for microcomputers--chips, floppy disks, hard disks, optical disks--and describes how secondary storage is used (file transfer, formatting, ingredients of incompatibility); disk/controller/software triplet; magnetic tape backup; storage volatility; disk emulator; and…

Introduces some algorithmic methods, for which no pre-editing is necessary, for automatically "lemmatising" raw text (changing raw text to an equivalent version in which all inflected words are artificially transformed to their dictionary look-up form). The results of a study of these methods, which used a German Text, are also given. (KM)

The Occupational Shortages Reporting System (OSRS) is a computerized system developed to produce quick and accurate reports on occupational shortages for given time periods and given occupations in Texas. The system's salient features are: easy and fast retrievability of information; expandability of the data base (from the present 1,254…

This manual describes a text processing system developed to teach relatively inexperienced users how to enter and edit textual materials. Also provided is information on storage and system maintenance for the system manager. It contains nine sections and two appendices with sections two through nine arranged in a sequence which corresponds closely…

The purposes of this study were to determine the nature of human semantic memory and to obtain knowledge usable in the future development of computer systems that can converse with people. The work was based on a computer model which is designed to comprehend English text, relating the text to information stored in a semantic data base that is…

This report presents the rationale, structure, content and procedures for the computerized bank of reading objectives being developed for New York State schools. The project was initiated to provide a technical resource which would contribute to planning, design, and evaluation of reading programs. The report defines the organizing concepts for…

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…
