- Abstract
- This paper describes part of a university research project which aims to construct a design method involving interactive multimedia products for knowledge acquisition. The purpose of the method is to design truly interactive multimedia products (Vidalenc, 1997), and thus to introduce a new form of writing. This is built up by adopting a constructivist paradigm that is based upon a systemic view and upon a network approach such as proposed by the sociology of translation (Callon, 1986). All our reflections are indeed based on the differentiation between two levels of information: an internal level and a sensitive level (Bouzidi and Vidalenc, 1997). However we have chosen a common model, the object oriented model, which allows us to represent the elements belonging to each level. In order to prove the validity of this proceeding, a prototype is under preparation. It is founded on the transposition of a course, which deals with telecommunications and networks, into a multimedia teaching tool. To be able to build up the prototype, taking into account the usual steps (writing the requirement schedule, choosing the necessary technology, modeling, design, implementation and evaluation), and after that, to be able to measure the conception method, a stage of analysis and assessment of the present course is necessary. The analysis of the course must allow us to identify the conditions of the knowledge transfer and provide components for the requirement schedule of the hypermedia product. This is the main subject of our reflections

- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- 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
- Navigating through hyperlinks within a Web site to look for information from one of its Web pages without the support of a site map can be inefficient and ineffective. Although the content of a Web site is usually organized with an inherent structure like a topic hierarchy, which is a directed tree rooted at a Web site's homepage whose vertices and edges correspond to Web pages and hyperlinks, such a topic hierarchy is not always available to the user. In this work, we studied the problem of automatic generation of Web sites' topic hierarchies. We modeled a Web site's link structure as a weighted directed graph and proposed methods for estimating edge weights based on eight types of features and three learning algorithms, namely decision trees, naïve Bayes classifiers, and logistic regression. Three graph algorithms, namely breadth-first search, shortest-path search, and directed minimum-spanning tree, were adapted to generate the topic hierarchy based on the graph model. We have tested the model and algorithms on real Web sites. It is found that the directed minimum-spanning tree algorithm with the decision tree as the weight learning algorithm achieves the highest performance with an average accuracy of 91.9%.
