Craven, Timothy C. – Proceedings of the ASIS Annual Meeting, 1992
Describes research that investigated a method of automatically generating concept association maps that could be useful to abstractors. The use of word stems as concept surrogates, cooccurrence to define concept links, and a general-purpose graph-drawing algorithm is described; and results of evaluation of two link selection methods are reported.…

Petry, Frederick E.; And Others – Proceedings of the ASIS Annual Meeting, 1993
Describes an approach that combines concepts from information retrieval, fuzzy set theory, and genetic programing to improve weighted Boolean query formulation via relevance feedback. Highlights include background on information retrieval systems; genetic algorithms; subproblem formulation; and preliminary results based on a testbed. (Contains 12…

Snyder, Herbert; Kurtze, Douglas – Proceedings of the ASIS Annual Meeting, 1992
Discusses the use of chaos, or nonlinear dynamics, for investigating computer-mediated communication. A comparison between real, human-generated data from a computer network and similarly constructed random-generated data is made, and mathematical procedures for determining chaos are described. (seven references) (LRW)

Spink, Amanda; Saracevic, Tefko – Proceedings of the ASIS Annual Meeting, 1993
Discussion of the selection of search terms during an online search involving users and intermediaries focuses on a study that investigated at what stage of the search process search terms from different sources were selected, how terms were connected with retrieval of relevant answers, and the sequences in which terms were selected. (Contains 16…

Lin, Xia – Proceedings of the ASIS Annual Meeting, 1995
Describes an experiment that was designed to compare three different map displays used as a visual display for information retrieval by either a self-organizing algorithm or human subjects. Results indicate that the organization and visual appearance of map displays had a significant effect on subjects' searching and browsing on the map displays.…

Rosenberg, Jason B.; Borgman, Christine L. – Proceedings of the ASIS Annual Meeting, 1992
Discusses the Science Library Catalog, an online catalog intended for use by children at the Los Angeles Public Library, and describes the process of reorganizing the MARC-based database by using clustering algorithms to extend the Dewey Decimal Classification. Examples of screen displays are included. (18 references) (LRW)
