Automated generation of composite web services based on functional semantics

Dong-Hoon Shin, Kyong-Ho Lee, Tatsuya Suda


Most of studies on the automated generation of composite Web services create composite services by
chaining available services’ inputs and outputs, but do not consider their functional semantics. Therefore,
unsatisfied results may be generated against users’ intentions. Furthermore, the time complexity is very
high since every possible combination of available services should be considered. To resolve these problems,
we propose a compositionmethod that explicitly specifies and uses the functional semantics ofWeb
services. Specifically, the proposed method is based on a graph model, which represents the functional
semantics ofWeb services.
