Constructing DOverlay of P2P Network to Support Semantic Based Searching
在P2P网络中构建支持语义搜索的覆盖网络DOverlay

P2P network is covered with an overlay topology to support the resources' fast locating.Overlays posses the semantic intelligence can manipulate the complicated queries,such as semantic queries.We propose a P2P Overlay based on ontology concept trees which can adapt to the varied characteristics of the P2P networks.The resource clusters can be formed automatically according to their ontology attributes.D_Search policy applied on DOverlay can effectively improve the successful rate of the resource searching ...
