Collaborative Home Media Community with semantic support

The great success of social technologies such as media sharing, blogs and wikis, is transforming the Internet into a collaborative community. This paper presents our research towards the exploitation of P2P networks, semantic metadata and social tagging for home media sharing, with a vision of P2P-based Collaborative Home Media Community (CHMC). The goal of the proposed CHMC is to enable sharing, searching and tagging of multimedia contents based on semantic metadata within home networks as well as between homes connected by broadband networks. We will firstly present a hierarchical P2P network architecture where the super-peer model is applied. The super peers act as a gateway bridging the inner home network with the external Internet. We further propose the Resource Description Framework (RDF) triple-based metadata indexing, retrieving and tagging algorithms on structured P2P networks. Finally, a prototype is developed for the purposes of system validation and performance evaluation.
