    Abstract
    This article introduces a new concept and technique for information retrieval called 'colinked descriptors'. Borrowed from an analogous idea in bibliometrics - cocited references - colinked descriptors provide a theory and method for identifying search terms that, by hypothesis, will be superior to those entered initially by a searcher. The theory suggests a means of moving automatically from 2 or more initial search terms, to other terms that should be superior in retrieval performance to the 2 original terms. A research project designed to test this colinked descriptor hypothesis is reported. The results suggest that the approach is effective, although methodological problems in testing the idea are reported. Algorithms to generate colinked descriptors can be incorporated easily into system interfaces, front-end or pre-search systems, or help software, in any database that employs a thesaurus. The potential use of colinked descriptors is a strong argument for building richer and more complex thesauri that reflect as many legitimate links among descriptors as possible

    Abstract
    Presents a state of the art review of the literature of expert systems in library and information science, involving exhaustive searches of all major LIS CD-ROM databases (LISA, ERIC, LiLi, INSPEC etc.) and bibliographies appended in review articles. The search retrieved 679 references, comprising 362 periodical articles, 180 conference proceedings, 63 books articles, 28 theses and 46 monographs. The growth of the literature peaked between 1989 and 1990 and subsequently declined after 1992. Over 1/3 (287) covered intelligent front ends and interfaces for online searching and retrieval, followed by applications in reference service (113), classification, indexing and abstracting (86) and cataloguing (7). The most productive periodicals comprised 6 titles, of which 'Information processing and management' topped the lsit: 43 authors were found to contribute between 5 and 35 articles each, hence contributing 32,19% of the total contributors. 382 of the publications were single author works, 172 were by 2 authors, 72 were by 3 authors and 49 were by 4 or more authors. Only 161 titles were expressive enough to reveal both the name and function of systems being developed

    Abstract
    Reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used included terms filtering, automatic indexing, and cluster analysis. The testbed for the research was the Worm Community System, which contains a comprehensive library of specialized community data and literature, currently in use by molecular biologists who study the nematode worm. The resulting worm thesaurus included 2709 researchers' names, 798 gene names, 20 experimental methods, and 4302 subject descriptors. On average, each term had about 90 weighted neighbouring terms indicating relevant concepts. The thesaurus was developed as an online search aide. Tests the worm thesaurus in an experiment with 6 worm researchers of varying degrees of expertise and background. The experiment showed that the thesaurus was an excellent 'memory jogging' device and that it supported learning and serendipitous browsing. Despite some occurrences of obvious noise, the system was useful in suggesting relevant concepts for the researchers' queries and it helped improve concept recall. With a simple browsing interface, an automatic thesaurus can become a useful tool for online search and can assist researchers in exploring and traversing a dynamic and complex electronic community system
