An Interactive Annotation System to Support the Learner with Web Services Assistance

Many annotation systems proposed in the learning domain suffer from an under-exploitation of the annotation´s semantics at the level of the assistance presented to the learner during his annotative activity. Thus, these tools offer the same classic features to its users, such as management, search, sharing and storage of annotations. In this paper, we propose a new annotation system which differs in its novel features. The system tries to assist the learner via web services during his learning activities. Therefore, from a user´s annotation, our application is able to interpret a goal implicitly expressed and tries to discover and invoke a web service that can meet this annotation´s objective. This tool is based on an annotation model composed of an ontology and pattern annotation. The evaluation of the developed annotation system using Student´s t-test confirmed that the learners are more motivated to annotate with our annotation tool than other systems.
