Web Service-Oriented E-learning: Proposition of Semantic Approach to Discover Web Services Related to the E-learning System

Service Oriented Computing (SOC) is a new paradigm for the flexible, scalable, and cost-effective development of distributed web applications and software. SOCs are widely used for their combination of existing web services, to efficiently create value-added applications. This paradigm, which has proven its efficiency in many fields and various information systems such as e-commerce, is considered to be very beneficial in the field of e-learning. This approach introduces the concept of discovery and invocation of web services published in service directories. Indeed, this document offers an infrastructure to discover web services related to the field of education. This proposition is based on the use of the e-learning domain ontology, the semantic descriptions of web services by OWL-S Language (Web Ontology Language for Web Services) as well as a matching algorithm, to find the adequate services that best meet the requests of users of the e-learning system.
