A grid service composition algorithm based on domain template

In this paper, a grid service composition algorithm based on domain template is proposed, where the domain template is constructed by the description model and evaluation model of grid service. The proposed algorithm can help users transparently combine the service at the operation level, satisfy the dynamic business requirements and improve the efficiency of service composition. The algorithm constructs the domain template by abstracting, concluding and summarizing the common demands of a certain domain, which implements the apparent expression of cooperative logic and the separation between cooperative logic and computing logic. The algorithm makes the software control structure transparent to users and implements the automatic choice of the domain template for service composition based on the service domain.
