Abstract: Aiming to the collaborative commerce characteristics of dynamics, multi-domain and heterogeneity in open network environment, a cloud-model-based subjective trust quantification method for collaborative commerce environment was proposed. Then, a cloud-model-based trust updating algorithm was presented. Furthermore, a test in simulation environment validated the algorithm, which demonstrated that the cloud-model-based method could resist malicious recommendation effectively while activate positive recommendation.

Key words: collaborative commerce, subjective trust, trust quantification, cloud model, equivalent experience, trust updating algorithm
