Current service composition and coordination still remain at large amount of manual processing stage, which has brought about low efficiency. In this paper, we present an efficient algorithm for abstract service discovery and a service instance selection method. Our algorithm firstly builds up the special data structures of ontology concepts based on graph storage theories when publishing abstract services. Then, these data structures form a quick service query list. In our algorithm, the large

In addition, our service instance selection methods based on OWL QoS ontology can enable grid resource sharing and coordination more flexible. 2007 IEEE Asia-Pacific Services Computing Conference 0-7695-3051-6/07 $25.00
