- Abstract
- The history of encyclopedias and wholly new forms of encyclopedias are briefly reviewed. The possibilities and problems that hypertext presents as a basis for new forms of encyclopedias are explored. The capabilities of current systems, both experimental and commercially available, are outlined, focusing on new possibilities for authoring and design and for reading the retrieval. Examples of applications already making use of hypertext are given.

- Abstract
- Analyzes an abstract model for hypermedia pplications. The model, Labyrinth, allows: the design of platform-independent hypermedia applications; the categorisation, generalisation and abstraction of unstructured heterogeneous information in multiple and interconnected levels, the creation of personalisations in multiuser hyperdocuments for both groups and individual users and the design of advanced security mechanisms for hypermedia applications

- 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

- Abstract
- Hypertext uses a browsing rather than a searching strategy. Hypertext systems have found applications in a number of areas. They give users choice of information but this can prove a drawback. Examnines the effectiveness of hypertext as a way of retrieving information and reviews conventional information retrieval techniques. Considers previous attempts at combining information retrieval and hypertext and outlines a prototype systems developed to generate guided tours for users to direct them through hypertext to information they have requested. Discusses how adding this kind of itelligent guidance to a hypertext system would affect its usability as an information system

- Abstract
- Considering the characteristics of hypertext systems and problems such as cognitive overload and the disorientation of users, this project studies subject hypertext documents that have undergone conceptual structuring using facets for content representation and improvement of information retrieval during navigation. The main objective was to assess the possibility of the application of topic map technology for automating the compatibilization process of these structures. For this purpose, two dissertations from the UFMG Information Science Post-Graduation Program were adopted as samples. Both dissertations had been duly analyzed and structured on the MHTX (Hypertextual Map) prototype database. The faceted structures of both dissertations, which had been represented in conceptual maps, were then converted into topic maps. It was then possible to use the merge property of the topic maps to promote the semantic interrelationship between the maps and, consequently, between the hypertextual information resources proper. The merge results were then analyzed in the light of theories dealing with the compatibilization of languages developed within the realm of information technology and librarianship from the 1960s on. The main goals accomplished were: (a) the detailed conceptualization of the merge process of the topic maps, considering the possible compatibilization levels and the applicability of this technology in the integration of faceted structures; and (b) the production of a detailed sequence of steps that may be used in the implementation of topic maps based on faceted structures.

- Abstract
- Discusses a new approach to information systems, the hypertext functionality approach. This focuses on incorporating hypertext features into information systems providing users with an alternative way of organizing, analysing and accessing information. Hypertext functionality is seen as a value-added support functionality for information systems, allowing the documents to be investigated in a non-linrea, semi-structured way. A core hypertext functionality applicable to any information system is presented here, driven from general hypetext concepts. Different implementation possibilities are also discussed

- Abstract
- Hypertext is an old concept that only recently has been demonstrated in working systems. Examines the conceptual basis of hypertext, reviews some representative hypertext systems, and discusses some of the problems to be faced when hypertext techniques are applied to large-scale information systems. Techniques developed in information retrieval research are seen as useful complements to hypertext that may remedy some of these problems.

- 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
- 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
- Hypermedia information systems, because of their inherent qualities of nonlinearity and associative linking, offer the potential of facilitating enhanced knowledge representation and construction for users. These capabilities will be more fully realized if hypermedia information systems are developed and implemented based on constructivist learning theory. Examines the qualities of hypermedia systems that enable them to facilitate learning, discusses the background of current learning theories and provides a brief view of a possible hypermedia system based on constructivist learning principles that could be developed through the use of intellegent autonomous agents

- Abstract
- Presents a 3 dimensional model of information exploration. An attempt is made to clarify the respective roles of the human and the system in browsing and information retrieval, and to characterise alternative interaction styles to maximise retrieval effectiveness. Illustrates the applicability of the model of exploration by describing 8 paradigmatic cases of information exploration that represent different vertices of the model. Describes initial experiment that attempted to assess the pragmatic impact of various combinations of exploration features. Discusses methods for integrating hypermedia and information retrieval into general information exploration systems and discusses some of the processes that people use in information exploration. Argues for the development of hybrid information systems combining exploration features in the most appropriate way according to the task needs of users

- Abstract
- State of the art review of hypertext systems in use in UK libraries. Systems include public access point of information (POI) systems that provide guidance to users of local resources, and networked document retrieval systems, such as WWW, that enable users to access texts stored on machines linked by the Internet. Particular emphasis is placed on those systems that are produced inhouse by the libraries in which they are used. The review is based on a series of telephone or face to face interviews conducted with representatives of those organizations that a literature review and mailed questionnaire survey identified as current users of hypertext. Considers issues relating to system development and usability, and presents a set of appropriate guidelines for the designers of future systems. Concludes that: the principle application of hypertext systems in UK libraries is in the implementation of POI systems; that such development is most advanced in the academic sector; and that such development is set to increase in tandem with use of the WWW
