Abstract

The article presents a conceptual framework for distinguishing different sorts of heterogeneous digital materials. The hypothesis is that a wide range of heterogeneous data resources can be characterized and classified due to their particular configurations of hypertext features such as scripts, links, interactive processes, and time scalings, and that the hypertext configuration is a major but not sole source of the messiness of big data. The notion of hypertext will be revalidated, placed at the center of the interpretation of networked digital media, and used in the analysis of the fast-growing amounts of heterogeneous digital collections, assemblages, and corpora. The introduction summarizes the wider background of a fast-changing data landscape.

Abstract

Purpose - The paper aims to review Deleuze and Guttari's concept of the rhizome as a model for information organisation. Design/methodology/approach - This is a critical review of selected literature. Findings - The rhizome concept is a promising model for understanding hyperlinked information services. It may be of practical value, particularly if it can be integrated with more traditional forms of information organisation. More research, conceptual and practical, is needed before this can be achieved. Research limitations/implications - The literature review is not comprehensive, and the conclusions are open-ended. Originality/value - This is the only paper to review the rhizome concept in this way.

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

This research is focused on the continuation of the Hypertext Map prototype implementation - MHTX, proposed by Lima, (2004), with the general objective of transforming the MHTX into a semantic content management product facilitating navigation in context supported by customizable software that is easy to use, through high end desktop/web interfaces that sustain the operation of its functions. Besides, these studies aim, in the long run, to achieve the simplification of the information organization, access and recovery processes in digital libraries, making archive management by authors, content managers and information professionals possible.
