With the rapid growth of quantities of Web services

form of communities of Web services reduces operating cost of Web services significantly. Web services which have similar functionality should be deployed into a same community so that users can select a community by their functional requirements. A community can be regarded as a whole for users in an opening environment because of the relationship of cooperation among Web services in their community. A problem is how the community divides its whole profit to each provider of inside Web service fairly and appropriately. A method to divide the whole profit based on Shapley value is proposed which is a classical solution in cooperative game. Compact the inputs to compute Shapley value by using MC-nets to meet the actual situation and reduce computational complexity. The experiment shows the better performance and practicality than Shapley algorithm.
