This book is an anthology of fifteen articles examining the subject of Collaborative Virtual Environments (CVE) from different perspectives. It offers a comprehensive reference volume to the state-of-the-art in the area of CVE design and development. Capitalizing on an excellent mix of forty-seven co-authors from academia and industry, the book provides(More)
Throughout the years competence-based management approaches have proved to be a critical tool in human resource management, vocational training and performance management. As a result, competence-based approaches are often adopted as the key paradigm in both formal or informal education and training programs. Despite this fact, the Technology-enhanced(More)
In this paper we deal with the problem of dynamically selecting a knowledge route suitable to individual learner's needs and profile, through a set of learning resources. We engage parameters of the learner's cognitive style and create a multi-criteria utility model that evaluates available didactic methods, using initial evaluations upon a set of basic(More)

The Semantic Web is the emerging landscape of new web technologies aiming at web-based information and services that would be understandable and reusable by both humans and machines. Ontologies, generally defined as a representation of a shared conceptualization of a particular domain, is a major component of the Semantic Web. It is anticipated that(More)
This paper suggests an alternative to the traditional 'as a whole' approach of evaluating adaptive learning systems (ALS), and adaptive systems, in general. We argue that the commonly recognised models of adaptive systems can be used as a basis for a layered evaluation that offers certain benefits to the developers of ALS. Therefore, we propose the layered(More)
A coding method for wavelet coefficients of images using vector quantization, called successive approximation vector quantization (SA-W-VQ) is proposed. In this method, each vector is coded by a series of vectors of decreasing magnitudes until a certain distortion level is reached. The successive approximation using vectors is analyzed, and conditions for(More)
Adaptive instructional planning or sequencing is recognized as one of the most interesting research questions in intelligent learning management systems. In this paper, we address the adaptive learning object sequencing problem in intelligent learning management systems proposing a concrete methodology based on the use of ontologies and learning object(More)
