Semantic annotation of web resources is an essential ingredient to leverage the web of information to the semantic web where resources are easily shared and reused. In the education field, reusing hypermedia web resources can support to a great deal the design of modern instructional environments and the development of interactive and non-linear material for learning. Sharing and reusing these resources by different web applications and services presupposes that they are visible for retrieval through a semantic description of their content, function and relations with other resources. This paper presents the annotation and discovery of web resources to create learning objects that constitute the building blocks of learning sessions which are delivered to users in the Web of Learning. Semantic annotation is done by the contextual exploration method which analyzes web resources’ text descriptions and metadata in order to annotate automatically resources. We present the system architecture and a case study that illustrates the proposed approach.
