Abstract: Data mining in cloud computing environment was proposed as a solution, in order to solve the task of distributed massive data analyzing in network and promote development integration and business application of data mining.The solving mechanism of data mining service was explained by computing capability and service model of cloud computing. Data mining in cloud computing environment is a service model of information resources in network. Based on these,the data mining service architecture was constructed, and the data mining service creating procedure was designed. The system architecture of data mining service model was depicted. The service process of data mining was defined. The data mining service model in cloud computing was formed consequently.

Key words: Data mining,Service,Cloud computing
