Cohen, Jonathan D. – Journal of the American Society for Information Science, 1995
A statistical method of drawing index terms or "highlights" from text is presented that uses no stop list, stem or other language- and domain-specific components, allowing operation in any domain or language with minimal modification. Some experimental results are presented, showing operation in six different languages. (67 references)…

Salton, Gerard – 1972
A comparison was made of the performance in an automatic information retrieval environment of user queries and document abstracts available in natural language form in both English and French. The results obtained indicate that the automatic indexing and retrieval techniques actually used appear equally effective in handling the query and document…

Chen, Hsinchun; And Others – Journal of the American Society for Information Science, 1995
This research reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used include term filtering, automatic indexing, and cluster analysis. The Worm Community System, used by molecular biologists studying the nematode worm C. elegans, was used as the testbed for this research.…

Figa, Elizabeth; Tarau, Paul – Proceedings of the ASIST Annual Meeting, 2003
Describes a framework for building "story traces" (compact global views of a narrative) and "story projects" (selections of key elements of a narrative) and their applications in text understanding and classification. The resulting "abstract story traces" provide a compact view of the underlying narrative's key…

Byrne, Jerry R. – Journal of the American Society for Information Science, 1975
Investigated the relative merits of searching on titles, subject headings, abstracts, free-language terms, and combinations of these elements. The combination of titles and abstracts came the closest to 100 percent retrieval. (Author/PF)

Van Cott, Harold P.; Zavala, Albert – 1967
Much of the periodical literature within scientific disciplines is characterized by overlap in content among journals and by scatter of content areas across journals. This obscures the inherent structure that may exist within the literature of discipline, creating problems for authors seeking suitable publication outlets, for editors wishing to…

Farradane, J.; Yates-Mercer, Penelope A. – Journal of Documentation, 1973
Some of the factors that must inevitably affect the assessment of printed indexes are discussed, together with the observation of two unexpected phenomena, namely an apparent relationship between precision and searching effort, and relationships between generality and both recall and fallout. (4 references) (Author)

Keenan, Stella; Elliott, Marna – Special Libraries, 1973
FID and NFAIS are jointly preparing a machine readable inventory of information for computer publication as a directory to abstracting services of the world. The kinds of data recorded by the Services are described. A progress report and plans for the future are included. (9 references) (Author/DH)

Breton, Ernest J. – Bulletin of the American Society for Information Science, 1981
Proposes indexing technical information by function and attribute instead of indexing by subject to increase retrieval efficiency. Reasons for the lack of accurate and comprehensive technical product information in databases and the need for an improvement in reference services are discussed. (RBF)
