    Abstract
    Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

    Abstract
    Describes SIFT (Search in Free Text) an information retrieval system originally developed for administering governmental documents in Norway but which is now being applied alsewhere. SIFT handles structured information well. A library system, SIFT-BIBL, is now available. SIFT's retrieval engine and search facilities are powerful. Its user interface is limited but being imporved. An application programmer interface has been released which will allow programmers to develop their own interface. A Windows-based- client-server version is now being beta tested

    Abstract
    Compares and contrasts online searching on DataStar using the 'classic' command language, with access via the more recent Web interface (DataStar Web). The search functionality of the 2 interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike

    Abstract
    A new search paradigm, in which the primary user activity is the guided exploration of a complex information space rather than the retrieval of items based on precise specifications, is proposed. The author claims that this paradigm is the norm in most practical applications, and that solutions based on traditional search methods are not effective in this context. He then presents a solution based on dynamic taxonomies, a knowledge management model that effectively guides users to reach their goal while giving them total freedom in exploring the information base. Applications, benefits, and current research are discussed.

    Abstract
    The authors describe user interface tools based on search histories to support legal information seekers. The design of the tools was informed by the results of a user study (Komlodi, 2002a) that examined the use of human memory, external memory aids, and search histories in legal information seeking and derived interface design recommendations for information storage and retrieval systems. The data collected were analyzed to identify potential task areas where search histories can support information seeking and use. The results show that many information-seeking tasks can take advantage of automatically and manually recorded history information. These findings encouraged the design of user interface tools building on search history information: direct search history displays, history-enabled scratchpad facilities, and organized results collection tools.

    Hypertext for multi-media and full-text documents is rapidly developed on all fronts. For bibliographic information retrieval the applications are promising but pose several difficulties. Describes work conducted at the School of Library and Information Science at Univ. of Western Ontario the objective of which is to add the capability of a browsing search to an existing OPAC through the use of Windowed Hypertext Interface for Zippy Retrieval and Display (WHIZRD) software. Discusses the underlying retrieval capabilities of the system. Examines design problems and solutions and outlines future enhancements

    Abstract
    Human-computer interaction is a very important topic in studying computerized information retrieval systems, as it takes into account both the human searchers and the information system features. This entry surveys the major research streams and applications of interactive information seeking and retrieval. It also presents how the expectations and requirements for interactive information seeking and retrieval have been expanded and what the challenges are ahead for evaluating such systems.

    Abstract
    Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system

    Abstract
    CD-ROM data bases are being adopted rapidly by libraries and are being made available to end-users. Compares online information retrieval systems and CD-ROM based retrieval systems, assessing structure and content characteristics that contribute to user behaviour. CD-ROM systems are comparable in database content and in interface style, although CD-ROM systems often provide multiple user interfaces, have smaller databases, less time pressure, and no telecommunications requirements. Some of the differences might lead to better retrieval performance by novice users, but many unanswered questions remain about the influence of time pressure, database size, interface style, training, and skill transfer among systems

    Abstract
    Describes an experiment using 48 sixth-grade students to compare retrieval techniques using the print and CD-ROM versions of Compton's Encyclopedia. Four queries of defferent complexity (measured by the numer of terms present) were searched by the students after a short training session. The searches were timed and the retrieval steps and search terms were noted. The searches were no faster on the CD-ROM than the print version, but in both cases time was related directly to the number of terms involved. The students coped well with the CD-ROM interface and its several retrieval paths
