    Abstract
    Hypertexts are electronic documents divided into interconnected fragments of text, which can be accessed directly thus evading the limitations of the linear structure of printed documents. The user can interact dynamically with the information and establish new relations. Describes the component features of such systems (hard and software) in relation to their applications (macro-literary, problem exploration, generic). The advantages of flexible organisation of texts, reference linkage and simultaneous access outweigh such disadvantages as the problem of constructing systems for a range of diverse user needs, making hypertext a significant aid to creative thinking

    Abstract
    Explores the hypothesis that using a zooming graphical interface minimizes user disorientation when reading documents in an electronic environment. 36 graduate students at the University of Maryland at College Park, USA, were randomly assigned to read a hypertext document in either Pad++, a zooming graphical interface, or Mosaic, a jump-based interface. Questionnaires, observation, and taped interviews were used to compare and evalutae the use of the 2 interfaces with regard to learning time, performance and user satisfaction. Findings suggest as workstations become more powerful, a hybrid interface that adds continuous zooming to the existing mechanisms of scroll, pan and jump will emerge

    Abstract
    Some people argure that hypertext is easy to write, is hard to create by converting existing text into hypertext, and has a massive market. This paper argures the contrary. First, Hypertext is hard to write. Second, automatically converting a text into hypertext is, to a first approximation, easy. Third, successful marketing of hypertext depends on having a large volume of material that is also available in paper form

    Abstract
    This article examines searcher behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Search times and number of nodes visited were recorded for five specified search queries, and views of the system were recorded for each searcher. No significant differences were found in search times or user satisfaction with the system, indicating that a hypertext-based approach to bibliographic retrieval could be appropriate for a variety of searcher experience levels

    Abstract
    Natural language generation techniques can be used to dynamically produce hypertext dynamic catalogues on the Web, resulting in DYNAMIC HYPERTEXT. A dynamic hypertext document can be tailored more precisely to a particular user's needs and background, thus helping the user to search more effectively. Describes the automatic generation of WWW documents and illustrates with 2 implemented systems

    Abstract
    Proposes a conceptual model to examine hypertext information presentation effects on decision making performance when compared with traditional sequentional information presentation and access. Considers which combination of task knowledge type (superficial, and causal) and information presentation styles (sequential, hypertext) yield the best decision making performance. This is achieved by comparing performance effect of hypertext and sequential information presentation when applied to superficial and causal type of knowledge required for the task. The 2 surrogates used for measuring the outcome of the performance effects are decision time and secision accuracy

    Abstract
    In a hypertext database, the information is presented as a network of nodes connected by links. Such nodes may be text, graphics, audio, video, and even other software. Although hypertext provides a new approach to information management, it also leaves a whole new set of problems for the designers of the hypertext database to solve. As the volume of information grows, the task of authoring a hypertext database becomes much more complex. In this article, the author presents the experiences during the development of a hypertext version of the user's guide for information services on JANET, in the UK, by using HyperPAD, a hypertext shell for the IBM PC. It may be the first step to explore the proper way to solve those problems which come together with the increasing application of hypertext

    Abstract
    The node size that should be used in a hypermedia system is an important design issue. 3 interpretations of node size are identified: storage (physical size), window size (presentation size), and length (logical size). an experiment in which presentation size and text length are varied in a HyperCard application is described. The experiment involves student subjects performing a fact retrieval task from a reference handbook. No interaction is found between these 2 independent variables. Performance is significantly better for the longer texts, but no significant difference is found for the 2 different window sizes

    Abstract
    Richer graph models permit authors to 'program' the browsing behaviour they want WWW readers to see by turning the hypertext into a hyperprogram with specific semantics. Multiple browsing streams can be started under the author's control and then kept in step through the synchronization mechanisms provided by the graph model. Adds a Semantic Web Graph Layer (SWGL) which allows dynamic interpretation of link and node structures according to graph models. Details the SWGL and its architecture, some sample protocol implementations, and the latest extensions to MHTML

    Abstract
    We present a declarative language for the construction of hypertext views on databases. The language is based on an object-oriented data model and a simple hypertext model with reference and inclusion links. A hypertext view specification consists in a collection of parameterized node schemes which specify how to construct node and links instances from the database contents. We show how this language can express different issues in hypertext view design. These include: the direct mapping of objects to nodes; the construction of complex nodes based on sets of objects; the representation of polymorphic sets of objects; and the representation of tree and graph structures. We have defined sublanguages corresponding to particular database models (relational, semantic, object-oriented) and implemented tools to generate Web views for these database models

    Abstract
    Models administrative and operating costs surrounding a hypermedia database and determines 7 conditions for the cost justification of hypermedia; higher linking costs proportionately reduce the total number of links implemented; increasing the benefits from using the database increases the total number of links proportionately; increasing database size results in an increase in the total number of links implemented; if the database user learns from the database slowly, then a larger number of links need to be provided: the maximum size of databases which is justified on cost will increase as the average cost of linking each node becomes smaller; the total benefit from usage required in order to cost justify a database will decrease as the average cost of linking each node becomes smaller and the maximum size of database which is cost justified will increase rapidly as the learning rate increases. The learning rate can be increased by construction of links and nodes so that they are maximally informative

    Abstract
    With the growth of hypertext and multimedia applications that support and encourage browsing it is time to take a penetrating look at browsing behaviour. Several dimensions of browsing are exemined, to find out: first, what is browsing and what cognitive processes are associated with it: second, is there a browsing strategy, and if so, are there any differences between how subject-area experts and novices browse; and finally, how can this knowledge be applied to improve the design of hypertext systems. Two groups of students, subject-area experts and novices, were studied while browsing a Macintosh HyperCard application on the subject The Vietnam War. A protocol analysis technique was used to gather and analyze data. Components of the GOMS model were used to describe the goals, operators, methods, and selection rules observed: Three browsing strategies were identified: (1) search-oriented browse, scanning and and reviewing information relevant to a fixed task; (2) review-browse, scanning and reviewing intersting information in the presence of transient browse goals that represent changing tasks, and (3) scan-browse, scanning for interesting information (without review). Most subjects primarily used review-browse interspersed with search-oriented browse. Within this strategy, comparisons between subject-area experts and novices revealed differences in tactics: experts browsed in more depth, seldom used referential links, selected different kinds of topics, and viewed information differently thatn did novices. Based on these findings, suggestions are made to hypertext developers
