- Abstract
- Defines and explores the use of problem solving heuristics in user interface design. A demonstration hypertext system, Hyperwriter, was developed as the outcome of considering general problems solving heuristics as goals of interactive systems design. Whereas hypertext joins and relates ideas, Hyperwriter additionally, and as a direct outcome of the design approach, has ways of separating, ordering and polishing ideas as an application for creative writing. Hypertext supports effective thinking over a period of time. Discusses some issues arising in implementing Hypertext

- Abstract
- We present in this paper a navigation approach using a combination of functionalities encountered in classification processes, Hypertext Systems and Information Retrieval Systems. its originality lies in the cooperation of these mechanisms to restrict the consultation universe, to locate faster the searched information, and to tackle the problem of disorientation when consulting the restricted Hypergraph of retrieved information. A first version of the SYRIUS system has been developed integrating both Hypertext and Information Retrieval functionalities that we have called Hypertext Information Retrieval System (H.I.R.S.). This version has been extended using classification mechanisms. The graphic interface of this new system version is presented here. Querying the system is done through common visual representation of the database Hypergraph. The visualization of the Hypergraph can be parameterized focusing on several levels (classes, links,...)

- 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%.

- Abstract
- Presents a study of problem solving activities in a hypermedia representation of a theorem proving problem. The users interacted with a system called HUGH&ME which presented users with 2 representations simultaneously. The respresentations were such that any operations carried out on the other. Describes a quantitative analysis of user activities, and a qualitative analysis of users' responses to questions asked during the session. Discusses the need for hypermedia based tools to support expression and refinement of users' reasoning when engaged in hypermedia-based problem solving activities

- Abstract
- Experiential learning theory, introduced by Kolb, suggests that people develop different learning styles. A study was conducted to determine whether or not individuals who exhibit certain learning styles are more successful in using a hypermedia problem solving system. The Learning Style Inventory was used to classifiy subjects into 4 groups based on their learning styles: converger, diverger, assimilator, and accomodator. The study found that learning style had an impact on problem solving quality when using the hypermedia system. The preferred learning style in a hypermedia based problem solving environment is the converger. In terms of learning orientation, abstract conceptualizers performed a higher quality of hypertext based problem solving than those who prefer concrete experience

- Abstract
- The lack of complete and accurate citations for referenced works is a persistent and significant problem in scholarly writing. The advent of new froms of electronic publishing, especially hypermedia, has the potential for either aggravating or alleviating this problem. Incorrect and missing citations will become more prevalent (and, indeed, have become so within large bibliographic databases) without a concerted and ccoperative effort on the part of systems developers to provide adequate references and the means for easily accessing and downloading them. Examines some of the basic issues involved in the problem of maintaining the critical authorship links between source and expression in one specific form of electronic publishing - hypermedia - and proposes some solutions

- Abstract
- One of the key objectives of knowledge management is to transfer knowledge quickly and efficiently from experts to novices, who are different in terms of the structural properties of domain knowledge or knowledge structure. This study applies experts' semantic networks to hypertext navigation design and examines the potential of the resulting design, i.e., semantic hypertext, in facilitating knowledge structure acquisition and problem solving. Moreover, we argue that the level of sophistication of the knowledge structure acquired by learners is an important mediator influencing the learning outcomes (in this case, problem solving). The research model was empirically tested with a situated experiment involving 80 business professionals. The results of the empirical study provided strong support for the effectiveness of semantic hypertext in transferring knowledge structure and reported a significant full mediating effect of knowledge structure sophistication. Both theoretical and practical implications of this research are discussed.

- 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
