Abstract This article is about an upcoming feature in the Journal of Universal Computer Science ([J.UCS, 2002]) related on typed-links. We will introduce the concept of “Links to the Future” in context of the journal. Articles published in J.UCS are stored in an object-oriented database. Therefore features such as fulltext- and index-search are already available out-of-the-box. With the concept of “Links to the Future” it is possible to automatically generate a link to an already published article in J.UCS. Utilizing the paradigm of bidirectional links will help the reader to use this additional information about an article. It will be shown that this concept is limited to articles stored in the local database. However, a simple extension (i.e. working with so called surrogate-objects) will make it possible to enhance this idea to resources referenced in articles published in J.UCS. References to traditional resources (books and other printed material) are also analyzed. In the electronic environment several techniques (such as DOI, Digital Object Identifier) are available to refer to an unique electronic resource. Using surrogates of traditional material makes it possible to link to traditional material. Identification systems for traditional material (ISBN and ISSN) are already available and digital libraries should make use of them. To enable this feature it is necessary to add attributes to link-objects. Problems related to this upcoming feature are discussed. This article will give an outline and status report of the implementation work Read More Read Less

Abstract This paper introduces the method of describing the hyper-presentation using Petri-Net and proposes the method of detecting inconsistent hyper-link loop in the hyper-presentation description. The concept of a hyper-presentation, as an extension of a hypermedia, is the presentation in which time-varying multimedia presentations are dynamically linked together and a hyperlink’s context can be changed over time at any time during a continuous presentation. For the purpose of detecting such inconsistent hyperlinked loop, we propose Multi Dimensional Timed Petri-Net Model for specification of a multimedia hyperPresentation. Then, based on the model, two methods, one for detecting the inconsistent loop and the other for finding the critical path for the actual presentation of the hyper-Presentation specification are described.

Abstract The MOBIlearn project, co-funded by the European Commission, the National Science Foundation and AU Department of Education, Science and Training, is strategically positioned to provide relevant research outcomes in the field of innovative use of mobile environments to meet the needs of learners, working by themselves and with others. State-of-the-art mobile devices will be available. A new m-learning architecture will support creation, brokerage, delivery and tracking of learning and information contents, using ambient intelligence, location-dependence, personalization, multimedia, instant messaging (text, video) and distributed databases. Field trials will cover "blended learning" (as part of formal courses); "adventitious, location-dependent learning" (during visits to museums); and "learning to interpret information sources and advice" (acquiring medical information for everyday needs).
