    Abstract
    Capability and capacity in handling the topology of a special subject information field has made infomapping techniques and systems instrumental in information searching, monitoring and navigation. Applying the technique to communication networks can reveal the intellectual relationships among junior and senior researchers in the field, and can also show the continuing popularity of a particular researcher's citation record over time. Reports the use of Java in making a cartoon series of chronological maps based on citation analysis on a special subject field (nutrition and dietetics). The map making methods, Java programming, and statistical analysis of the map data are presented, and the advantage and significance of constructing Java maps in enhancing information retrieval discussed. Further technical developments in applying VRML to link together a 3-D spatial indexing system and a 2-D HTML Web site are suggested

    Abstract
    Science mapping is discussed in the general context of information visualization. Attempts to construct maps of science using citation data are reviewed, focusing on the use of co-citation clusters. New work is reported on a dataset of about 36.000 documents using simplified methods for ordination, and nesting maps hierarchically. an overall map of the dataset shows the multidisciplinary breadth of the document sample, and submaps allow drilling down the document level. An effort to visualize these data using advanced virtual reality software is described, and the creation of document pathways through the map is seen as a realization of Bush's associative trails

    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
    With the many choices that can be built into information systems, it is possible to customize such systems for users, based on the tasks that users are accomplishing, on the personal characteristics of users, or a combination of these factors. Reports results of an experiment which detailed logging of use of experimental information systems and was used to determine the optimal configuration of these systems for each user. 4 experimental systems were specially designed and all used a single database of 668 bibliographic records. Tasks were varied, and the cognitive abilities of users were tested to assess one important personal characteristic. Results showed that it was possible to create an optimal configuration to match the cognitive abilities of users, but that it was more difficult to assess which configuration was the best match for specific tasks. The person in task interaction proved to be the least powerful indicator of design configurations. These results suggest that usable information systems can be created for users by careful analysis of the interaction of design features with personal characteristics such as cognitive abilities

    Abstract
    Reports results of an evaluation study of 3 WWW based prototypes for bibliographic displays developed as part of an ongoing research project at the Faculty of Information Studies, Toronto University. The development of these prototypes builds upon results obtained in earlier phases of the project that addressed issues of both the content and form of bibliographic displays in OPACs. Anticipation of continued growth in the number of catalogues available through the WWW, combined with research evidence that existing Web based displays have not shown improvement over their text based counterparts, motivated the development of these prototypes for use on the Web. Reports findings from a focus group evaluation of the 3 prototypes and makes suggestions for future research

    Reports a survey conducted in April 1997 of 136 Japanese WWW and Telnet OPACs from the persepctive of their functions and user interfaces. These included: types of searchable files; access points; kinds of displays; login commands; search methods; Boolean operation; help functions; search history; and browsing of indexed terms. Results indicate a sharp rise in the number of WWW OPACs and problems with the provision of functions and user interfaces by Japanese WWW OPACs

    Abstract
    Reports results of a study to evaluate the OPACs in 12 Canadian academic libraries, using a checklist of functional capabilities and interface features of an ideal OPAC system, to serve as an evaluation standard or benchmark for evaluating the strenghts and weaknesses of the OPACs. Findings suggest that, among the 10 areas evaluated, screen displays is the best developed area, and subject search aids is the weakest. Identifies possible directions for the future development of OPACs and suggests areas for future OPAC research

    Abstract
    Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

    Abstract
    Reports the findings of a study, conducted by Temple, Barker and Sloane Inc., MA, which identified 7 measurable benefits of graphic user interfaces to computerized information retrieval systems; higher speed; more accurate work; higher productivity; less frustration; less fatigue, more facilities to self teach and explore system; greater facilities for novices to learn more about the system's capabilities. Concludes that, when compared with character based user interfaces, graphic user interfaces generate higher work outputs per work hour through higher productivity; higher work output per employee through lower levels of frustration and fatigue; and greater returns on information technology investment through reduced demand for user training

    Abstract
    The GUI is impacting library application software. Despite this trend, user satisfaction with the GUI has not been documented. The Parke-Davis Pharmaceutical Research Library, USA, undertook a study to determine user satisfaction with the new GUI based Dynix Marquis, as compared with the Dynix Classic OPAC. The study included a survey assessing user satisfaction and a review of overall usage. Survey findings show that the GUI based OPAC was preferred by end users over the text based OPAC. Usage reports supported the survey findings with significantly increased usage after migration

    Abstract
    Reports on work in progress to define an object oriented model of a probabilistic information retrieval system (OKAPI), the central component of which is the query itself. Considers how to represent queries both internally and at the user interface level, and their relationship with other components of the model. The model will form the basis of a configurable user interface, which allows controlled experiments to be undertaken, and could be adapted to the needs of different users accessing different databases. Implementation will involve the use of a high level interpreted scripting language for overall control, communicating with an internal model and an interface model, designed and developed using object oriented techniques

    Abstract
    PACE (Public Access Catalogue Extension) is an alternative user interface designed to enhace OPACs. PACE simulates images of books and library shelves to help users browse through the catalogue. Reports results of a study in which PACE was tested in a college library (Vanier College), in a real operational environment, against a second generation test based OPAC: Best-Seller. Results show that a simple browsable retrieval interface performed as well as a second generation OPAC in terms of retrieval speed and search success. The overwhelming majority of students, however, preferred the browsing capability of PACE through the familiar metaphor of books and library shelves to a text based OPAC
