Graphic Display of Larger Sentence Dependency Structures.
Peer reviewed Peer reviewed
Craven, Timothy C. – Journal of the American Society for Information Science, 1991
Outlines desirable qualities for graphic representation of sentence dependency structures in texts more than a few sentences in length. Several different display formats prototyped in the TEXNET experimental text structure management system are described, illustrated, and compared, and automatic structure manipulations are discussed.

Sentence Dependency Structures in Abstracts.
Peer reviewed Peer reviewed
Craven, Timothy C. – Library and Information Science Research, 1988
Describes the results of an analysis of 87 non-formulaic abstracts for structures of semantic dependency between sentences. An automatic structural simplification is presented which is based on an assumption about the use of the dependency structure, and the results of an evaluation of the method are discussed.

Condensed Representation of Sentences in Graphic Displays of Text Structures.
Peer reviewed Peer reviewed
Craven, Timothy C. – Journal of Documentation, 1990
Discusses ways in which sentences may be represented in a condensed form in graphic displays of a sentence dependency structure. A prototype of a text structure management system, TEXNET, is described; a quantitative evaluation of automatic abbreviation schemes is presented; full-text compression is discussed; and additional research is suggested.…

Algorithms for Graphic Display of Sentence Dependency Structures.
Peer reviewed Peer reviewed
Craven, Timothy C. – Information Processing and Management, 1991
Discussion of graph-drawing algorithms compares and evaluates five algorithms for generated automatic graphic display of sentence dependency structures that have been implemented in the TEXTNET text structure management system. Evaluation criteria are discussed, and a test of the algorithms with a database of newspaper articles is described. (16…

A Computer-Aided Abstracting Tool Kit.
Peer reviewed Peer reviewed
Craven, Timothy C. – Canadian Journal of Information and Library Science, 1993
Reports on the development of a prototype computerized abstractor's assistant called TEXNET, a text network management system. Features of the system discussed include semantic dependency links; displays of text structure; basic text editing; extracting; weighting methods; and listings of frequent words. (Contains 25 references.) (LRW)

An Experiment in the Use of Tools for Computer-Assisted Abstracting.
Craven, Timothy C. – Proceedings of the ASIS Annual Meeting, 1996
Experimental subjects wrote abstracts of an article using a simplified version of the TEXTNET abstracting assistance software; subjects were presented with either keywords or phrases extracted automatically. Results showed considerable variation among subjects, but 37% found the keywords or phrases "quite" or "very" useful in…
