Service Knowledge Reuse Strategy Based on Topological Model

The isolated service can not satisfy the rapid changing requirement of the customer; they need to be reconfigured and combined and to form a new service composition. Actually, the service reconfiguration is the reuse of service knowledge. And, the reuse should obey some strategy. This paper gives the formalized description of service knowledge and proposed a service knowledge reuse model by topological graphics. The model brings clarity and integrity to description of the relation among the service components.
