Assessing the integration of ontology tools in content network architectures

The realm of this paper is the provision of multimedia services based on matching users´ preferences and multimedia content descriptions. The main concept explored is the usage of ontology tools for mitigating frailties found in tag based matching processes due to their lack of semantic knowledge and their context dependence. The integration of ontology tools in CN architectures based on open standards (MPEG-7 and IMS) is proposed and assessed in this paper. The results obtained via non-functional tests enable to conclude that these tools provide enhanced matching results without a negative impact on both the CN size and its performance.
