Craven, Timothy C.; Fjerestad, Li – 1981
Prepared as a self-instructional tool for anyone interested in indexing documents from their titles using the NEsted PHrase Indexing System (NEPHIS), this manual introduces, defines, and provides guidelines for the use of this computer-assisted indexing system. The objectives of the system are outlined, the NEPHIS computer program and input…

Craven, Timothy C. – Journal of the American Society for Information Science, 1982
Describes a system for the automatic coding of most descriptive titles which generates Nested Phrase Indexing System (NEPHIS) input strings of sufficient quality for permuted index production. A series of examples and an 11-item reference list accompany the text. (JL)

Craven, Timothy C. – Information Processing & Management, 2001
Discusses automatic indexing methods and describes the development of a prototype computerized abstractor's assistant. Highlights include the text network management system, TEXNET; phrase selection that follows indexing; phrase display, including Boolean capabilities; results of preliminary testing; and availability of TEXNET software.

Craven, Timothy C. – Information Processing and Management, 1978
Describes a computer-assisted system for the production of printed indexes based on networks of concept relations expressed in natural-language-like form. The LIPHIS is designed to handle more complex networks of concept relations, and so produce better indexing of highly detailed subjects. (Author/CWM)

Craven, Timothy C. – Journal of Documentation, 1987
Describes a microcomputer-based string index format generated from concept networks using multiple search terms. Link weighting is highlighted as a method to decide which term appears first so the entry reflects the classification implied by the search specification. The computer software used for this system is briefly described. (Author/LRW)

Craven, Timothy C. – Journal of the American Society for Information Science, 1980
Proposes that error rates in indexing using string index languages such as NEPHIS might be reduced at relatively low cost by having the indexer enter strings via a microcomputer system which could provide simple validation and feedback in the form of graphic displays of concept links. (Author/FM)

Craven, Timothy C. – Information Processing and Management, 1988
Presents a methodology for extending string indexing from index display production to the provision of descriptor phrases for term proximity searching. Objectives of the extension are discussed, and an illustration of the use of an existing string indexing system for this purpose is given. (14 references) (CLB)

Craven, Timothy C. – Journal of Documentation, 1982
Describes an automatic display system which has been developed for the editing of concept subnetworks within a relational index and which employs only a floppy diskette drive and a PET 2001 microcomputer. Appendices on Farradane's Nine Relations and on the Graphic Editing System Commands and a reference list are included. (Author/JL)

Craven, Timothy C. – Proceedings of the ASIS Annual Meeting, 1993
Discusses the use of thesauri in automatic indexing and describes the development of a prototype computerized abstractor's assistant. Topics addressed include TEXNET, a text network management system; the use of TEXNET for abstracting; the structure and use of a thesaurus for abstracting in TEXNET; and weighted terms. (Contains 26 references.)…

Craven, Timothy C. – Information Processing and Management, 1980
Proposes a single underlying structure for the production of a variety of computer index displays, using a networking system which represents both concepts and links by nodes. Desirable characteristics of index displays are outlined, and algorithmic extraction of subnetworks for local use is discussed. References are included. (Author/BK)

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…

Declerck, Luc; Craven, Timothy C. – 1983
NETPAD is a microcomputer-based system, implemented on a Commodore PET 2001-8, by which a human indexer can input, retrieve, and edit information in order to produce a variety of permuted index displays. The basic unit of the NETPAD system is a subnetwork (a description of a single document) containing a set of concept nodes (author, title, date,…
