Current systems do not provide a context when sharing and reusing annotations. This research investigated how this may be achieved. This thesis provides an overview of the work that has been undertaken in the fields of Semantic Web, adaptive hypermedia system, and open hypermedia. This work discusses experiments that were conducted to assess the benefit of integrating Semantic Web technologies with open hypermedia and adaptive hypermedia concepts to provide adaptable hypermedia for users’ requirements. In this work, ontologies are used to explicitly define models, concepts, user profiles, context and semantic relationships. To enable sharing and reusability of information chunks as annotations, this research brings together several technologies: ontologies for knowledge representation, and extended FOHM to represent the structure of annotations. A contextual annotation framework (CAF) using an ontology-based contextual annotation service is proposed. The novel contribution of this work is introducing the CAF using an ontology-based contextual annotation service by building on open hypertext and the Semantic Web. The a-PIE is prototyped to provide a system for supporting browsing, reading, annotating hypertext, and manipulating interesting annotations in a personal repository. The framework has been applied to the specific domain of web development, in order to carry out a focused evaluation. The results indicate that the framework is valid.
