While most of the case studies reported so far involve a single social media tool or several individual, separate tools, in this paper we advocate the use of an integrated social learning environment, which aggregates several Web 2.0 tools (wiki, blog,(More)
Integrating learning styles in adaptive educational systems is a relatively recent trend in technology enhanced learning. The rationale is that adapting courses to the learning preferences of the students has a positive effect on the learning process, leading to an increased efficiency, effectiveness and/or learner satisfaction. The purpose of this paper is(More)
In this note we consider design of a information provisioning subsystem for an agent-based virtual organization. Flexible delivery of information is based on matching of ontologically demarcated resource profiles, work contexts, and domain specific knowledge.
This paper deals with adaptation provisioning with respect to learning styles in a Web-based educational system called WELSA. The novelty of the approach comes from using an integrative set of characteristics extracted from the main learning style models as adaptation criterion, rather than relying on a single learning style model, as most of the related(More)
This paper presents an approach for applying inductive logic programming to information extraction from HTML documents struc-tured as unranked ordered trees. We consider information extraction from Web resources that are abstracted as providing sets of tuples. Our approach is based on defining a new class of wrappers as a special class of logic programs –(More)
