    Abstract
    Describes a research project, at Middlesex Polytechnic, aimed at evaluating a front end thesaurus to navigate users through subject searches in on-line catalogues (OPACs). The British Library sponsored project involves the adaptation of the RIN file, used for thesaurual control of the British National Bibliography (BNB), to be used as a front end for a MARC data base with PRECIS subject indexing

    Abstract
    Suggest reasons why there is no operational OPAC station yet in Iceland. Obstacles include the lack of compatability among computer systems adopted by the major libraries, the differing classification schemes used by them and the lack of a controlled indexing vocabulary or thesaurus for subject analysis in the Icelandic language. The Rejkjavik Municipal Library and the National Hospital Library, both users of the DOBIS/LIBIS system, will be the first users of a potential network of OPACs.

    Abstract
    Focuses on the user and human-computer interaction (HCI) aspects of the research based on the Okapi text retrieval system. Describes 3 experiments using different approaches to query expansion, highlighting the relationship between the functionality of a system and different interface designs. These experiments involve both automatic and interactive query expansion, and both character based and GUI (graphical user interface) environments. The effectiveness of the search interaction for query expansion depends on resolving opposing interface and functional aspects, e.g. automatic vs. interactive query expansion, explicit vs. implicit use of a thesaurus, and document vs. query space

    Abstract
    Research conducted in the early 80's has shown that subject access is still one of the most dominant approaches in OPACs. However, while some of the subject searches result in no recall, others often retrieve so much that users are discouraged to proceed further. These and other problems were investigated and solutions were found in improving search methods (such as word stemming, extending search to full bibliographical record and providing end user thesaurus) and indexing techniques (such as ny enhancing subject headings with table of contents and back of the book indexes or by traditional systems). More recent research indicates that the real answer to the question of 'precision without sacrificing recall' lies in the developing 'user friendly novel interfaces' and also in designing 'knowledge based systems', wherein sers would not be expected to learn query formulation or even to be familiar with the indexing language of the system. Several interesting studies and research projects on the subject have produced a whole gamut of information, but one can still visualise the evolving trends of research vis-a-vis their future prospects as possible solutions
