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: 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: 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: 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: Describes computerized tools for computer assisted abstracting. FlipPhr is a Microsoft Windows application program that rearranges (flips) phrases or other expressions in accordance with rules in a grammar. The flipping may be invoked with a single keystroke from within various Windows application programs that allow cutting and pasting of text. The user may modify the grammar to provide for different kinds of flipping

Abstract

2 automatic techniques for modifying the structure of the thesaurus are described: automatic structure simplifications, and automatic addition of dummy terms. These techniques, especially when used together, can be used to simplify graphic thesaurus displays without sacrificing important information and they can also assist in correcting poorly structured theauri. Originally developed for sentence dependency structures in the TEXNET text structure management package, they are now available as options in the THSRS thesaurus management package

Abstract

Experimental subjects wrote abstracts of an article using a simplified version of the TEXNET abstracting assistance software. In addition to the fulltext, the 35 subjects were presented with either keywords or phrases extracted automatically. The resulting abstracts, and the times taken, were recorded automatically; some additional information was gathered by oral questionnaire. Results showed considerable variation among subjects, but 37% found the keywords or phrases quite or very useful in writing their abstracts. Statistical analysis failed to support deveral hypothesised relations; phrases were not viewed as significantly more helpful than keywords; and abstracting experience did not correlate with originality of wording, approximation of the author abstract, or greater conciseness. Results also suggested possible modifications to the software
