    Abstract
    Centralised systems continue to dominate the information retrieval market, with increased competition from CD-ROM based systems. As more large organisations begin to implement office automation systems, however, many will find that neither of these types of retrieval systems will satisfy their requirements, especially those requirements involving easy integration into other systems and heavy usage by casual end users. A prototype distributed information retrieval system was designed and built using a distributed architecture and using statistical ranking techniques to help provide better service for the end user. The distributed architecture was shown to be a feasible alternative to centralised or CD-ROM information retrieval, and user testing of the ranking methodology showed both widespread user enthusiasm for this retrieval technique and very fast response times

    Abstract
    The Text REtrieval Conference (TREC) workshop series encourages research in information retrieval from large text applications by providing a large test collection, uniform scoring procedures and a forum for organizations interested in comparing their results. Now in its seventh year, the conference has become the major experimental effort in the field. Participants in the TREC conferences have examined a wide variety of retrieval techniques, including methods using automatic thesauri, sophisticated term weighting, natural language techniques, relevance feedback and advanced pattern matching. The TREC conference series is co-sponsored by the National Institute of Standards and Technology (NIST) and the Information Technology Office of the Defense Advanced Research Projects Agency (DARPA)

    Abstract
    Reviews the overall results of the TREC experiments in information retrieval, which differed from other information retrieval research projects in that the document collections used in the research were massive, and the groups participating in the collaborative evaluation are among the main organizations in the field. Reviews the findings of TREC, the way in which it operates and the specialist 'tracks' it supports and concentrates on european involvement in TREC, examining the participants and the emergence of European TREC like exercises

    Abstract
    Most commercial on-line information retrieval systems are not designed to service end users and, therefore, have often built front-ends to their systems specifically to serve the end user market. These front ends have not been well accepted, mostly because the underlying systems are still difficult for end users to use successfully in searching. New techniques, based on statistical methods, that allow natural language input and return lists of records in order of likely relevance, have long been available from research laboratories. Presents 4 prototype implementations of these statistical retrieval systems that demonstrate their potential as powerful and easily used retrieval systems able to service all users. The systems consist of: the PRISE system; the CITE system; the Muscat system; and the News Retrieval Tool
