A Personalized Agent-Based E-Learning System Using Web Services and SOA

E-learning refers to learning that is delivered or enabled via electronic technology. Agent-based E-learning system retrieves relevant learning materials, process and analyzes data to enable meaningful E–learning recommendations to instructors and learners. Personalized agent-based E-learning system provide a set of personalization functionalities such as personalizing learning plans, learning materials, test and necessary instant messages etc., to online learners. In recent years, numerous efforts have been made in the direction of automating the content acquisition and distribution, but personalized content delivery, access and interaction remain research challenges. The objective of this paper is to provide a service-oriented architecture for personalized agent based e-learning system using web services. This architecture includes a teacher agent and learner agent. These agents achieve personalization in E-learning system and as a consequence to improve E-learning effectiveness dramatically. The proposed architecture is a layered architecture that consists of user layer, service registry layer, application layer and data layer. The various web services are identified and implemented in the proposed system. The proposed architecture using web services increases the efficiency and learning in terms of reusability, interoperability and accessibility. E-learning using agents and web services make the architecture more scalable and efficient.
