Knowledge trust evaluation theory based on ontology trust model

As the important resource in semantic network and the requirement on reliable measurement of evidence, the importance for researching trust of knowledge was reflected. Aiming at the trust of knowledge, the credibility evaluation system of knowledge resource under the network environment with the ontology as basic unit was researched, and the ontology trust model was built. Based on the ontology's self credibility, the Bayesian network-based ontology concept credibility model and the ontology mapping-based semantic information credibility model were built; based on the ontology's global credibility, the recommendation-based ontology overall recommendation credibility model and the ontology's environment credibility model were constructed. The cases were given to verify the effectiveness and advance of proposed model. ©, 2014, CIMS. All right reserved.
