| 摘 要： | 0 IntroductionThe goal of Semantic Webis to build a web of meaning.Semantic Web will consist of a distributed environmentof shared andinteroperable ontologies ,which have emerged ascommonformalisms for knowledge representation.It is prom-isingto combine P2P networks with Semantic Web technolo-gy. On one hand,P2P networks can help semantic web withsharing knowledge;onthe other hand,P2P networks use thesemantic concept to query routing and efficient content-basedlocation. However ,evenafter…

| Abstract: | A reputation mechanism is introduced in P2P- based Semantic Web to solve the problem of lacking trust. It enables Semantic Web to utilize reputation information based on semantic similarity of peers in the network. This approach is evaluated in a simulation of a content sharing system and the experiments show that the system with reputation mechanism outperforms the system without it. |
