Abstract: With the booming of social commerce in recent years, trust fusion in social networks has become a crucial factor in consumer's decision making. Consumers establish perceived trust based on personal experience and recommendation, whose essence is multi-sources trust fusion. Trust fusion model originating from computer science has been fully analyzed by scholars worldwide. In social commerce, similarities between new decision making and experiential decision making, as well as recommendations play an important role in consumers' decision making. However, some new challenges have emerged in social commerce due to the fuzziness and multi-sources of consumers' perceived trust. Therefore, multi-sources trust fusion of consumers' trust in social commerce needs to be further analyzed.
Focusing on the fuzziness of consumers' perceived trust, a fuzzy trust fusion model is established by combining cased-based decision theory (CBDT) and multi-attribute decision making based on intuitionistic fuzzy sets. Consumers' perceived trust stemmed from experience and recommendation, hence our model is composed of three parts in working process:empirical trust calculation, recommendation trust calculation and trust fusion of both these two. The key influencing factors of perceived trust have been integrated into multi-attribute decision making based on intuitionistic fuzzy sets, whereas empirical trust and recommendation trust have been calculated respectively within the framework of CBDT, both fused grounded on anchoring effect.
The effectiveness of our model has been tested by case study and data analysis. The impact of personal experience, similarity and consensus operator on perceived trust has been illustrated to reveal the process of transformation from experience and recommendation to perceived trust. In the data analysis, the data has been collected by questionnaire, and the calculation result of perceived trust has been compared with the survey data. The viability and effectiveness of our results on perceived trust were validated in comparison and improved by prediction accuracy.
Combining decision maker's experience and recommendation, our model merge several methods such as CBDT and intuitionistic fuzzy sets which enable us to refine the trust fusion model research with the frame and new perspectives. With the assistance of the proposed method for perceived trust measurement, a new way for E-commerce platform is provided to make precise marketing strategy through consumers' online reviews and related social relationship.

Key words: social commerce, trust fusion, perceived trust, intuitionist fuzzy set, case-based decision theory
