Intelligent Tutoring Interoperability for the New Web Interoperability of systems based on knowledge is a very important element for reducing their development cost and enabling an easytoperform service enrichment. An important subclass of distant learning systems is represented by intelligent tutoring systems (ITSs) that base their work on the simulation of the real teacher in the learning and teaching process. ITSs base their interoperability on interchange of domain knowledge, knowledge about learning and teaching process and knowledge about students. This paper describes a methodology for ensuring interoperability among DiSNeT, a distance learning system based on the intelligent tutoring paradigm, on knowledge presentation using distributed semantic networks and on using agents in the learning and teaching process, with other ITSs.

Competency Based Approach: Modeling and Implementation The expansion of computer networks has at the same time given impetus to the distance learning environments. Elearning systems are also advanced and more efficient. However, these platforms offer such complex teaching functionalities that designers find themselves poorly equipped to succeed in their engineering processes. This article presents a tool that makes it easier for designers to produce educational content according to the CompetencyBased Approach (CBA). We propose an implementation of the CBA after its modeling via ontology. Our module can be grafted to any author system oriented pedagogy based skills. We have advocated for Service for Oriented Architecture as a software solution to model our business process that consists of a set of interconnected services that are modeled and implemented. The proposed system is the result of a coordination of, services, incorporating the order of competences explained by a distance education, which integrates and interacts according to an orchestration plan.
