Logic Petri net based model for Web service cluster
Yuyue Du · Journal of Computer Applications · 2012
In clustering based Web service discovery,the service cluster is characterized by indeterminacy because parameters are uneven in name,quantity and order,which results in a great deal of work in parameter matching.For this reason,a logic Petri net based model for Web service cluster was proposed.It built map relationship between clusters and services by denoting the service parameter sets to logic vectors based upon clusters' parameter sets,and unified management for service parameters.Therefore,parameter matching based on semantic similarity is only necessary to process on cluster layer;whereas,in a service cluster,parameter can be located directly by position vector and parameter matching can be realized by logical comparison.The matching magnitude and computation complexity are reduced enormously,and the service discovery efficiency gets improved.
