Paper Title
Comparison between Two Developed Semantic System by using Connection with Protege Owl and by using Direct SPARQL Queries

when specifying privacy preferences, the data owner can control who may access its personal data, for which purpose and under which accuracy. This could be done either by developing a whole ontology or using SPARQL query. In this paper we develop the two approaches and compare between their performances. The two approaches will be applied on healthcare data access management systems. Keywords - Privacy, Data access management, SQL SPARQL Query, Protégé OWL
