A Trust Model of Web Services Based on Individual Experience

In Web services, the identical node may have different trust values in the different services domain because of the network complexity and the node´s asymmetry. The node´s individual difference is studied, and then one Web services trust model is proposed based on the individual experience by establishing quantitative and appraisal system. The Web services are divided into the different groups, and therefore the problem is solved that one node may have different reputation values in different services domain. The analysis indicates that the new model has improved the algorithm of feedback trust value very much.
