Towards a Service Based Architecture for Assessment

In this paper we propose the outline of a service based architecture for bringing assessment techniques to open e-learning environments. We first describe a use case scenario for a generic assessment framework offering personalized assessment generation and then present its basic architecture as part of the Personal Reader Framework. The generic assessment framework enables the search for the appropriate assessment resources after checking the learner’s last saved performances and specific needs (e.g. language preferences, device requirements). In our assessment framework personalization functionalities are available as web services. The communication between these services is based on the Semantic Web technologies and does not need a centralized control. The assessment functionalities are defined in a separate Web service, which a user can subscribe/ un-subscribe as s/he likes.
