A Formal Model of Learner’s Annotations Dedicated to Web Services Invocation

Abstract

Various models of learner’s annotative activity have been proposed in E-learning domain. This models which try to conceptualize the annotations of learner are used as basis of many annotations systems. In this article, we propose a new formal model of learner’s annotations dedicated to Web services invocation. This conceptual model, composed of ontology and pattern of annotation, tries to present the learner’s annotative activity as a means of invocation of appropriate Web services. Therefore, from a learner’s annotation we interpret a goal implicitly expressed and we try to discover and invoke a Web service which can meet the annotation’s object and consequently assist the learner in his learning activities.
