Abstract: To improve the collaboration of resource services among organizations,oriented to collaborative task systems,an approach for resource service sequence mining was proposed from workflow model and runtime data two levels.According to the task-related dependences between resource services in workflow model,an algorithm was proposed to resolve resource service sets,and an initial set of resource service sequences named resource service chain was obtained.To improve reusability of resource-service sequence,the initial resource service chain was taken as cluster center to extend all the resource service chains,and each new extended chain was operated to solve the similarities.Thus the modified cluster center was obtained.The effectiveness of proposed method was proved with experiment,and the analysis results showed that it could improve the selection efficiency,availability and utilization of resource services.
