- 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
- 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
- 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
- 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
- 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
- Presents a model of hypermedia that allows the combination of 'hyperstructured' information with dynamic multimedia information. The model is derived by extending the Dexter hypertext reference model and the Centrum voor Wiskunde en Informatica Multimedia Interchange Format (CMIF) multimedia model. Explains how the CMIF multimedia model builds on the model provided by Dexter. The Amsterdam hypermedia model enables the description of structured multimedia documents, incorporating time at a fundamental level and extending the hypertext notion of links to time-based media and compositions of different media

- Abstract
- In many hypertext systems authors are encouraged to create hierachical structures, but when writing, the hierarchy is lost because of the inclusion of cross-reference links. Looks at ways of recovering lost hierarchies and finding new ones, offering authors different views of the same hypertext. Identifies properties of the hypertext document. Develops multiple metrics including compactness and stratum - compactness indicates the intrinsic connectedness of the hypertext, and stratum reveals to what degree the hypertext is organised so that some nodes must be read before others. Uses several exosting hypertexts to illustrate the benefits of each technique. The collection of techniques provides a multifaceted view of the hypertext, which should allow authors to reduce undesired structured complexity and create documents that readers can transverse more easily

- Abstract
- This paper discusses some problems encountered in hypermedia-based collaboration and reuse, and presents a conceptual framework to resolve these problems. Three suggestions are made based on the discussion: (1) extra organizational structures are necessary in shared hypermedia to support collaborative interactions; (2) an abstract schema is a key to capture the dynamic nature of the shared hypermedia; (3) an integration of the schema evolution approach and the workflow approach is recommended for an open system hypermedia teamwork support. The whole authoring environment is divided into several component spaces with particular respect to the Dexter Hypertext Reference Model. Not only can this separation reduce the overall complexitiy of working within such an environment, but it also conforms more closely with human cognitive needs in collaborative authoring and reuse activities
