Abstract |
|
|
| Web service composition has received much interest due to its potential to achieve the visionary promise of Service-Oriented
Computing paradigm in which services can be utilized as the basic constructs to create flexible dynamic business processes and agile
applications that may span organizations and computing platforms with little effort even automatically. In this paper, we proposed
a snowball method for automated Web service composition which is based on service relation tracing which starts off rather like a
standard ego-centered network study. It discoveries one or several availableWeb services which can accept the input parameters in user
requirement through sematic reasoning and determines whether its output parameters meet the user requirements. And then it fetches
other candidate services following the Sequential-total and Sequential-partial relations, investigates their outputs, also asks further
sequential relations, and so forth through a succession of ”waves” of spreading. So the process is repeated and the composite service is
constructed incrementally tracing sequential relations in Service Network just like a snowball. The experiment shows that the approach
proposed in this paper can greatly improve the accuracy and efficiency of Web service composition. |
