Trust Network Based Fuzzy Knowledge Sharing in Semantic Web

In Semantic Web, knowledge, always imperfect, is managed by a myriad of autonomous, loose-coupled Web agents, which usually have different perceptions of fuzziness for given knowledge. This fact makes knowledge sharing more difficult in Semantic Web than in other finite-scaled environments. In this paper, we propose a trust network based fuzzy knowledge sharing model for Semantic Web. According to this model, any agent can broadcast its knowledge queries through the trust network, and aggregate different opinions according to the trustworthiness of each agent echoed. Keywords-Semantic Web; fuzzy knowledge; trust network
