Abstract

In this paper, an algorithm of automatically composing web services is present with rules mapping, in which an ontology model about I/O parameters from web services was built, and a mapping table was created which associated inputs with outputs parameters as rules. From the mapping rules all possible composition paths that meet the condition can be found out by search backward. At last the optimal composition path was selected to response users according to QoS level. The simulation experiment indicates this approach can fast find out all expected composition paths and reduce search space and time.
