Peer reviewedCraven, 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.

Peer reviewedCraven, 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.

Peer reviewedCraven, 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.…

Peer reviewedCraven, 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…
