A Novel Mobile Video Community Discovery Scheme Using Ontology-Based Semantical Interest Capture

الملخص EN

Leveraging network virtualization technologies, the community-based video systems rely on the measurement of common interests to define and steady relationship between community members, which promotes video sharing performance and improves scalability community structure.

In this paper, we propose a novel mobile Video Community discovery scheme using ontology-based semantical interest capture (VCOSI).

An ontology-based semantical extension approach is proposed, which describes video content and measures video similarity according to video key word selection methods.

In order to reduce the calculation load of video similarity, VCOSI designs a prefix-filtering-based estimation algorithm to decrease energy consumption of mobile nodes.

VCOSI further proposes a member relationship estimate method to construct scalable and resilient node communities, which promotes video sharing capacity of video systems with the flexible and economic community maintenance.

Extensive tests show how VCOSI obtains better performance results in comparison with other state-of-the-art solutions.
