Abstract :
The number of Web-Services publicly accessible through APIs have rapidly grown in recent years. Although, while these services are key in providing access to data as well as a variety of functionality, often their full potential remains yet to be fully exploited. Due to the different standards used to implement and expose Web services, it is usually cumbersome for developers to reuse them within third-party applications. In this paper, we present Service Graph Base, a unified graph-based platform for representing and manipulating service artifacts. It allows professional developers to add service knowledge to a graph base, which can be done either automatically or manually. By adopting the language-neutral RDF-based Graph Model and developing a uniformly-interfaced service editor for service native artifacts extraction, services are represented as RDF graphs in Service Graph Base. Once they are in the graph base, common SPARQL queries can be used to provide intelligent exploration over the base, thereby providing a unified approach regardless of the actual service type. In our work, we have harvested 4,925 Yahoo! pipes and 300 WSDLs for service artifacts extraction and service query. Experiments showed that 99.35% Yahoo! pipes and 100% WSDLs were successfully represented as RDF graphs.
