This investigation proposed a service-oriented approach based on a pervasive learning grid for solving the difficulties associated with sharing learning resources distributed on different e-Learning platforms. Furthermore, the p-Learning grid not only enabled collaboration and effective reuse of the learning objects, but also supported learning at anytime and anywhere. Since the WSDL of web ser...

One of the aims of ELENA project (www.elena-project.org) is to support personalized access to distributed learning repositories. In this talk we will present an approach to personalization we employed in ELENA. We take advantage of semantic web technologies and metadata description standards. Explicit descriptions of learning objects described in RDF bindings of LOM and DC, and learners in inte...

One of the most fundamental subtasks of information integration which comes up very often in day-to-day business and research is the publishing of documents, e.g. project plans, business reports, presentation layers, product designs, idea sketches, announcements, telephone lists, reports, advertisements or research papers. Actually, over 90% of companies knowledge is according to a study of the...

User clustering algorithms have been introduced to analyze users’ learning behaviors and help to provide personalized learning guides in traditional Web-based learning systems. However, the explicit and implicit coupled interactions, which means the correlations between user attributes generated from learning actions, are not considered in these algorithms. Much significant and useful informati...

Web services composition present a technology to compose complex service applications from individual (atomic) services, that is, through web services composition, distributed applications and enterprise business processes can be integrated by individual service components developed independently. In this paper, we concentrate on the optimization problems of dynamic web service composition, and...

The emergence of Web 2.0 triggered a general trend towards online social interactions and brought sociology in the global interactive picture. The emergence of Web 2.0 has brought about the opportunity to create new educational uses of Web 2.0 user centred software. Social software platforms, human networks, and human activities in Web 2.0 refer to a set of technologies for sharing information ...
