An interactive search and editing system, 3RIP, is being developed at the library of the Royal Institute of Technology in Stockholm for large files of textual and numeric data. A substantial part (on the order of 10-E9 characters) of the primary file of the search system will consist of bibliographic references from a wide range of sources. If the…

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…

The Inverted File Information Retrieval System (INFIRS), is a document search system which offers a comprehensive range of search facilities. It has been developed at the United Kingdom Chemical Information Service (UKCIS) as a general purpose retrieval tool, suitable for handling a wide variety of data-bases (both free-text and controlled…

This study sought to design an effective management information system for an Illinois community college. It was developed by (1) displaying all the college activities as a system with six functionally independent subsystems, (2) reducing subsystem data to basic elements, (3) analyzing administrator response to choice of data items, (4)…

Introduction to use of compact disk technology for storing digital data highlights history, background, and developments; technical features; standardization issues; current CD ROM applications; and the market for CD products. A production diagram, a sampling of CD manufacturers and disk replicators, and performance comparison of three storage…

Review of similarities and differences between magnetic-based and optical disk drives includes a discussion of the electronics necessary for their operation; describes benefits, possible applications, and future trends in development of laser-based drives; and lists manufacturers of laser optical disk drives. (MBR)

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…

Describes a survey of publishers and database producers that examined their activities regarding the retention and storage of electronic material, and access to that material. The discussion covers the archival life of various electronic media, standards relating to electronic publishing, and initiatives in electronic archiving. The questionnaires…

While data processing cannot, as yet, provide automatic translation, computer assistance is valuable for information storage and retrieval in dictionary work, text-related glossaries, and text banks. (CK)

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)

Efficient search of items in a store of information, such as books in a library, abstracts of articles, information in a computer data bank or the like, requires that the items most closely connected in content be close together, in order that a person looking for some particular information may concentrate his search on as small a part of the…

Survey of recent developments in microcomputer technology, mass-storage technology, and telecommunications technology shows how these new technologies are driving the development of a new generation of information systems. Major changes in the information industry precipitated by arrival of new information systems and telecommunication…

Discusses the dilemmas created by photocopying, computing, and other neopulishing technologies in the light of existing copyright laws, analyzes the costs and benefits of computer-based information storage and retrieval systems and photocopying technologies, and suggests guidelines for developing future public policy. (JR)

Knowing how to store documents for easy retrieval can be an art, but it can be learned. Just as a computer is only as good as the information and program which is fed into it, a filing system's value depends on the logic with which it was planned to respond to certain needs. (Author/SSH)

Reveals how chemical information in the form of descriptions of the chemical literature and chemical substances can be encoded as digital representations, then manipulated by computers to assist with collection, formatting, and distribution. Explains how computer-based search techniques are used to search databases that supplement traditional…
