    Abstract
    HIFI (ESPRIT project 6532) creates a set of tools to allow a reader to access a large body of heterogeneous information, managed by external databases created beforehand, through a hypertext interface. The HIFI approach is a model-based description of the hypertext application as it appears to the reader. A declarative and/or operational mapping translates hypertext operations (search, queries and navigation) into operations on the underlying information base and also 'materialises' hypertext objects, using objects of the underlying databases. The system supports hypertext development. Illustrates this with the cooperation of end users as partners or project sponsors

    Abstract
    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
    Reviews SmarText from Lotus Development Co. which creates and retrieves electronically stored reference materials and documents. The software builder automatically analyzes electronic versions of documents assembles its own outlines and indexes and establishes hypertext links between text and illustrations. Documents can be searched either by browsing through the text, using the outline to find a specific section, or selecting from the index. A Boolean search feature allows searching for combinations of terms. Examines the strengths and weaknesses of the program. Smartext is best suited to documents developed internally or in the public domain because of copyright law

    Abstract
    Reports on research which aims to discover the path patterns through which users retrieve information in hypertext systems. Takes a pragmatic approach in which the use of a hypertext information retrieval system by a group of subjects was monitored to collect path pattern data. Two frequency distribution models were developed and tested using these data. Path length followed a shifted negative minimal distribution. The influence of search tasks on path patterns was examined and found to have no effect. These models can provide a background for examination of systems via stimulation studies

    Abstract
    Traditional hypertext adds structure to electronic documents by linking related concepts. This hypertext is normally produced by the author that specialises in the production of electronic documents. Describes a system, ConQuest, that eliminates the need for hypertext produced by authors. ConQuest is a natural language, concept based text search, retrieval and browsing engine that automatically finds related concepts in a document using linguistic processing and a built in lexical knowledge base. Because of its high accuracy, ConQuest can link document concepts dynamically, acting as a form of intelligent hypertext

    Investigates how linkage environments in a hypertext based bibliographic retrieval system affect retrieval performance for novice and experienced searchers, 2 systems, 1 with inter record linkages to authors and descriptors and 1 that also included title and abstract keywords, were tested. No significant differences in retrieval performance and system usage were found for most search tests. The enhanced system did provide better performance where title and abstract keywords provided the most direct access to relevant records. The findings have implications for the design of bilbiographic information retrieval systems using hypertext linkages

    Abstract
    The aim of probabilistic models is to define a retrieval strategy within which documents can be optimally ranked according to their relevance probability with respect to a given request. Presents a study which suggests representing documents not only by index term vendors, as proposed by previous probabilistic models but also by considering relevance hypertext links. To enhance retrieval effectiveness, the learning retrieval scheme should modify the weight assigned to each indexing terms, the importance attached to each search term, and the relationships between documents. Evaluation of the proposed retrieval scheme with a hypertext based on the CACM test collection which includes 3.204 documents and the CISI corpus (1,460 documents), yields interesting results on the retrieval effectiveness of this approach

    Investigates the effects of context-weks versus context-strong tasks and learning style on the citation frequencies and citation percentages of 4 mental models students perceived to be inherent in a hypermedia learning environment. The 4 mental models were semantic networks, concept maps, frames / scripts and schemata. They were further grouped as linear. In study 1 the search participants could cite as many of the 4 mental models as they chose for each of the target commands, features or tools, in study 2 they were limited to citing only one

    Abstract
    We have recently completed a survey of the operational use of hypertext-based information systems in academic, public and special libraries in the UK. A literatur search, questionnaire and both telephone and face-to-face interviews demonstrate that the principle application of hypertext systems is for the implementation of public-access point-of-information systems, which provide guidance to the users of local information resources. In this paper, we describe the principle issuse relating to the design and usage of these systems that were raised in the interviews and that we experienced when using the systems for ourselves. We then present a set of technical recommendations with the intention of helping the developers of future systems, with special attention being given to the need to develop effective methods for system evaluation

    Abstract
    Describes a study which investigated the affective response of 83 subjects to 2 versions of a hypertext-based bibliographic retrieval system. The objective of the study was to determine if subjects preferred searching a hypertext information retrieval (IR) system via traditional bibliographic links or via an enhanced set of linkages between structured records. The study also examined the utility of using factor analysis to explore subjects' affective responses to searching the 2 hypertext-based IR systems; explored the effect of experience on search outcome; and compared the effect of different types of linkages within the hypertext system. Findings reveal a complex relationship between system and user that is sometimes contradictory. Searchers found the systems to be usable or unusable in different ways indicating that further researchg is needed to isolate to specific features that searchers find frustrating or not in searching structured records via a hypertext-based IR system

    Abstract
    Introduces a generic approach to the development of hypermedia information systems. Emphasises the role of intrinsic inter-document relationships in structuring and visualising a large hypermedia information space. Illustrates the use of this approach based on 3 types of similarity measurements: hypertext linkage, content similarity and usage patterns. Salient patterns in these relationships are extracted and visualised in a simle and intuitive associated network. The spatial layout of a visualisation is optimised such that closely related documents are placed near to each other and only those intrinsic connections among them are shown to users as automatically generated virtual links. Supports self-organized information space transformation based on usage patterns and othe feedback such that the visual strucutre of the information space is incrementally tailored to users' search and browsing styles
