Intelligent tutoring interoperability for the new Web

The interoperability of the system based on knowledge is a very important element for the reduction of development cost and it also enables an easy-to-perform service enrichment. An important subclass of distant learning systems is represented by an intelligent tutoring systems (ITSs) that base their work on the simulation of the "real" teacher in the learning and teaching process. The interoperability of the ITSs is based on the interchange of domain knowledge about learning and teaching process and the knowledge about students. This paper describes a methodology for ensuring interoperability on DiSNeT, a distance learning system based on the intelligent tutoring paradigm. This paper also describes the use of distributed semantic networks on knowledge presentation and the use of agents in the learning and teaching process, with other ITSs.
