Abstract
To improve efficiency and accuracy of semantic web service composition, a topic maps oriented semantic web service composition policy is proposed. Firstly describes topic maps and web service with ontology, then defines a service composition view to implement service composition mapping. Secondly, a matching dependency for semantic web service is defined, and employ greedy genetic algorithm to optimize the results. Finally, this paper implements the method based Amazon services set and the results show that it is better efficiency than old method.
