Abstract

Special reference is made to the possible use of automatically generated displays as an aid to abstracters. Some advantages of three-diemnsional displays are outlined with experimental results conforming their reduced distortion of concept space. Features that may set three-dimensional representations of concepts space off from other kinds of three dimensional representations are noted. Features of a prototype system operating on a microcomputer with VGA display are described and illustrated

Abstract

This article ic concerned with how sentences may be represented briefly but informatively in graphic desplays of a sentence dependence structure. Different automatic abbreviation schemes were assessed on a sample data set for compression and ambiguity. 'Speedwriting' of words longer than five letters yielded a compression to 80% of the source text, with very low ambiguitiy. This and two other automatic notemaking-like techniques have been implemented as options in the TEXNET text structure management system

Abstract

Describes the abstracting assistance features being prototyped in the TEXNET text network management system. Sentence weighting methods include: weithing negatively or positively on the stems in a selected passage; weighting on general lists of cue words, adjusting weights of selected segments; and weighting of occurrence of frequent stems. The user may adjust a number of parameters: the minimum strength of extracts; the threshold for frequent word/stems and the amount sentence weight is to be adjusted for each weighting type

Abstract

A multi-purpose thesaurus is among abstracting assistance features being prototyped in the TEXNET text networking management system. The thesaurus is intended to support vocabulary control, including production of a variety of printed thesaurus displays, as well as automatic weighting of passages and Roget-style suggestions of alternate terms

Abstract

Ideas on computerized graphic displays of concept networks are surveyed, with reference to both recent and early research. While the emphasis is on syntactic and semantic relations and on indexing and information retrieval applications, attention is also paid to related areas
