Nowadays, Internet technologies and standards are being systematically used by enterprises as tools to provide an infrastructure to connect people, enterprises, and applications they are using. In such complex networked enterprises, it is increasingly challenging to interchange, share, and manage internal and external digital information. In this context,(More)
The use of ontologies as tools to guide the generation, organization and personalization of e-learning content, including e-assessment, has drawn attention of the researchers because ontologies can represent the knowledge of a given domain and researchers use the ontology to reason about it. Although the use of these semantic technologies tends to enhance(More)
With the emergence of the Semantic Web several domain ontologies were developed, which varied not only in their structure but also in the natural language used to define them. The lack of an integrated view of all web nodes and the existence of heterogeneous domain ontologies drive new challenges in the discovery of knowledge resources which are relevant to(More)
A collaborative B2B relationship implies jointly executing business processes. This relationship demands a complete access to available information and knowledge to support decision-making activities between trading partners. To support information interchange between enterprises in collaborative B2B ecommerce there are some XML-based standards(More)
Nowadays, organizational innovation constitutes the government challenges for providing better and more efficient services to citizens, enterprises or other public offices. E–government seems to be an excellent opportunity to work on this way. The applications that support front-end services delivered to users have to access information systems of multiple(More)
During the last year, approaches that use ontologies, the backbone of the Semantic Web technologies, for different purposes in the assessment domain of e-Learning have emerged. One of these purposes is the use of ontologies as a mean of providing a structure to guide the automated design of assessments. The most of the approaches that deal with this problem(More)
