Great number of publicly accessible and available Web services is found on the Web through Web sites, repositories or catalogs managed directly by service providers. Recent surveys proved that those services are poorly documented or annotated with semantic information. Consequently, using those services is still quite a challenge. Besides, reusability is a tenet of SOA implementation that can bring interesting return on investment. We would like to tackle the issue of public Web service reusability by allowing their end-users to socialize them based on their usage experiences. We then propose a mechanism to express this socialization process and exploit resulting data to promote the reuse (usage, discovery, selection, recommendation and composition) of public Web services, in a supporting system.
