Discussion of database design that allows wider range of capabilities than conventional information retrieval database covers prestructuring of searches to pinpoint target items, which are selected from browseable display, and navigation capability, which allows user to move from record to record within database to facilitate extraction of…

Describes various ways in which software systems for online catalogs can be designed to enhance subject access. Highlights include what to search (subject headings, titles, notes, authority-file records, classification numbers, and associated text); truncation and stemming; spelling correction; search strategies (headings, keywords, Boolean…

The National Library of Medicine's Current Information Transfer in English public access online catalog offers unique subject search capabilities--natural-language query input, automatic medical subject headings display, closest match search strategy, ranked document output, dynamic end user feedback for search refinement. References, description…

Describes software for displaying documents on computer graphics screens which provide the opportunity for interactive user interfaces. Based on a software system called Guide, this new approach relies on advances in hardware, such as the CD ROM, and can be used in the front end of a document retrieval system. (Author/LRW)

Describes a computer-assisted learning (CAL) system which incorporates a front-end processor for controlling communication between terminal user and mainframe, and the accessing and displaying of invariant information (held on microfiche) at the appropriate terminal. (Author)

THE NAVAL AVIONICS FACILITY, INDIANAPOLIS (NAFI) TECHNICAL LIBRARY IS PLANNING A MECHANIZED SYSTEM TO PRODUCE A PERMUTED INDEX OF PERTINENT PERIODICAL REFERENCES AND PROCEEDINGS, WITH BOOKS AND DOCUMENTS TO BE ADDED LATER. INPUT TO THE SYSTEM IS PUNCHED PAPER TAPE PREPARED FROM THE SOURCE MATERIAL, AND THE PRIMARY PROGRAM IS A "CANNED"…

A visual information display and retrieval system (VID-R) is described for application to visual records. VID-R searches and retrieves events by time address (location) or by previously stored ovservations or measurements. Fields are labeled by writing discriminable binary addresses on the horizontal lines outside the normal viewing area. The…

CONTENTS--(1) AN ASSOCIATIVITY TECHNIQUE FOR AUTOMATICALLY OPTIMIZING RETRIEVAL RESULTS BY RONALD R. ANDERSON. AN ASSOCIATIVE TECHNIQUE BY WHICH IT IS POSSIBLE TO AUTOMATICALLY EXPAND AND NARROW THE NUMBER OF DOCUMENTS RETRIEVED AND TO RETRIEVE DOCUMENTS RELATED TO A REQUEST EVEN THOUGH THEY MAY NOT BE INDEXED BY THE EXACT TERMS OF THE REQUEST IS…

This thesis describes work done as part of the Video Console Indexing Project (VICI), a program to improve the quality and reduce the time and work involved in indexing documents. The objective of the work described was to design a video terminal system which could be connected to a main computer to provide rapid natural communication between the…

Describes in detail features of the IBM personal computer's components--computer, keyboard, monitor, printer, modem--and outlines specific choices for one searching machine that works well (system unit, disk drives, adapter boards, monitor, printer, modem, cables, options, supplies, software). Reasons to choose IBM personal computer for online…

INTERACTIVE COMPUTER SYSTEMS ESTABLISH A DIALOG BETWEEN THE MAN AND THE MACHINE. BY MEANS OF DISPLAYS, THE USER RECEIVES IMMEDIATE FEEDBACK OF THE RESULT OF HIS ACTIONS, AND HE IS ABLE TO MODIFY HIS DECISIONS IN ORDER TO OBTAIN A SYSTEM RESPONSE THAT IS MOST RELEVANT TO HIS NEEDS. BOLD (BIBLIOGRAPHIC ON-LINE DISPLAY) IS AN EXAMPLE OF A HIGHLY…

The VID-R (Visual Information Display and Retrieval) system that enables computer-aided analysis of visual records is composed of a film-to-television chain, two videotape recorders with complete remote control of functions, a video-disc recorder, three high-resolution television monitors, a teletype, a PDP-8, a video and audio interface, three…

This unclassified-unlimited bibliography contains 183 references, with abstracts, dealing specifically with optical or graphic information processing. Citations are grouped under three headings: display devices and theory, character recognition, and pattern recognition. Within each group, they are arranged in accession number (AD-number) sequence.…

In this research project, subject terms from the Dewey Decimal Classification (DDC) Schedules and Relative Index were incorporated into an online catalog as searcher's tools for subject access, browsing, and display. Four features of the DDC were employed to help searchers browse for and match their own subject terms with the online catalog's…

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…
