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

Considers why the use of hypermedia has not been more widely accepted and applied in practice, given that it is such a powerful information handling technique and it has been commercially available for 5 years. Argues that hypermedia is not sufficiently open or transparent to users, enabling them to find relevant information relatively easily and at a high level of sophistication. Suggests that a higher degree of transparency can be obtained by taking into account a variety of issues which can best be accomodated by the designation information ecology

Abstract

Criticizes the current processes of information management, with the objective of arriving at a new concept of the electronic document. Discusses problems of human language in the context of information management. Examines the problem of information from the point of view of the structure of knowledge, by analysing dysfunction in current processes of information management. Proposes a model of knowledge nearer to the human mind called 'document hypertext'. A combined interface of information management id also applicable in studies of hardware, graphic interfaces and metaphors of visualization of information. The current excessive fragmentation and artificial treatment of information structures could be avoided by simplifying of processes of information management and creating integral interfaces that bring information systems closer to the user

Abstract

The paper consists of a series of charts and diagrams rather than a text. Considers the way in which users of printed information sources develop a mental map to assist them in navigation and transfers the psychological concepts underlying the development of such mental maps to the design of hypertext searching systems for computerized information retrieval

Abstract

Proposes a theoretical framework for organizing information and activities in educational hypermedia systems. Focuses on the content that can be represented within a physical media, rather than the physical media itself. Proposes a theory of cognitive media types based on the inferential and learning processes of human users. Presents an implemented computer system, called AlgoNet, that supports hypermedia information access and constructive learning activities for self paced learning in computer and engineering disciplines

Abstract

As part of ongoing investigation of information seeking behaviour of end users in electronic environments, a comparison was made of those users having expertise in a topic area and those with expertise in online searching. Computer scientists and online search specialists conducted assigned searches in a HyperCard database on the topic of hypertext. Both groups of experts were able to conduct successful searches and outperformed a novice control group. Search specialists took slightly less time tahn the domain experts, modified queries by adding terms found in the text, and tended to focus on query formulation. Domain experts focused on the text and used their domain knowledge for further question answering

Abstract

The development of electronic publishing heralds a new period in scientific communications. Besides the obvious advantages of an almost endless storage and transport capacity, many new features come to the fore. As each technology finds its own expressions in the ways scientific communication take form, we analyse print on paper scientific articles in order to obtain the necessary ingredients for shping a new model for electronic communications. A short historical overview shows that the typical form of the present-day linear (essay-type) scientific article is the result of a technological development over the centuries. The various characteristics of print on paper are discussed and the foreseeable changes to a more modular form of communication in an electronic environment are postulated. Subsequently we take the functions of the present-day scientific article vis-à-vis the author and the reader as starting points. We then focus on the process of scientific information transfer and deal essentially with the information consumption by the reader. Different types of information, at present intermingled in the linear article, can be separated and stored in well-defined, cognitive, textual modules. To serve the scientists better in finding their way through the information overload of today, we conclude that the electronic transfer of the future will be, in essence, a transfer of well-defined, cognitive information modules. In the last part pf this article we outline the first steps towards a heuristic model for such scientific information transfer

Abstract

Parallels are frequently drawn between navigating through everyday spatial environments and information systems, hypertexts being a particular case in point. Examnines the cognitive mapping theory often borrowed implicitly from spatial cognition research which has a bearing on the appropriateness of using spatial imagery in hypertext. identifies conceptual differences between euclidean and virtual spaces and considers ways in which to make information spaces more coherent. Describes demonstration hypertext browser incorporating some of the cognitive principles discussed

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

As a growing learning technology, hypermedia needs to be examined in terms of the cognitive processes it encourages in users. Descusses the characteristics that circumscribe hypermedia. Presents 2 perspectives on learning from hypermedia: purpose of usage (culture, education, information) and usage context. Describes 4 cognitive processes involved in hypermedia usage: browsing, searching, integrating, and angling (establishing multiple perspectives). Discusses 2 cognitive pitfalls: hyperspace wandering and cohesion deficit

Abstract: Presents a study on hypertext examining the cognitive styles and spatial ability of users; the complexity of tasks; and the strucutre of information organization and the visualization of the structure. Future work on hypertext usability should emphasize task taxonomies along with longitudinal and ethnographic studies for a deep understanding of the interactions between users and hypertext
