Abstract: How to package various web services that involve lots of complex operations so as to turn them into web service communities or web service clusters is discussed. Based on the web service log where various web services are indefinitely involved, a web service packaging method is proposed using the sequential-pattern mining technique. The method is implemented the way the technique is applied to mining the log to find out the serving function sequence which is then used to package various web service operations and form different functional services, thus providing web service communities/clusters. The web service communities/clusters thus packaged are available to support the dynamic service composition.
