Context_aware in Web service dynamic trusted model
Chunmei Liu · Computer Engineering and Applications Journal · 2011
Existing approaches for trust model often have inadequate support for the change of environment.In order to bridge this gap,a context ontology-based Web service dynamic trust computing model is proposed.This model awares the context of entities which affects the trust relationship,and transform them into different input values.In this model,the method of objective and subjective combination weighting and fuzzy comprehensive evaluation are adopted to evaluate the relationship of trust between the entities.The simulation compared with EigenTrust model,by changing time and the context of entities,result indicates the model is effective and feasible.
