For trust is subjective, ambiguous, and has other characteristics, this paper proposed an affair-based interpersonal trust metric calculation method to quantify the value of trust. The method defined two trees, one is "trust performance tree" in which the main factors affecting trust are abstractively subdivided into different levels of trust performance, and the other is "affair behavior tree" in which the affairs of daily lives are subdivided into different types and each affair has one or more behavior details. Supported by an affair-based trust logical data model, this method can establish mapping of the two treespsila nodes and obtain appraisement data. Based on the large amounts of appraisement data, this method acquired the trust value by iterative calculation. An affair-based trust metric calculation model was built according to the method above.
