SemSUP: Design and implementation of semantic enhance social-aware user profile

This paper proposes a semantic enhance social-aware user profile to address the issues of capturing and modeling user information for personalized services and contents. We also identify design requirements for user-centric profile to enhance its applicability in different domains and usage scenarios. In addition, the paper also provides the refinement algorithm to confine the user profile to most recurrent preferences. We use a policy base approach to ensure user privacy and authorize sharing of profile information with third parties. We formally represent authorization policies by exploiting Semantic Web Rule Language. The paper also provides evaluation of the proposed ontology by comparing it with the selected existing user profile ontologies.
