Dynamic Web Service Composition Using Google API Crawling

Abstract

Service Oriented applications are becoming very popular due to ease of Web services Usage. The area of Web Service Discovery (WSD) is a primary area of research today. It has fundamental importance in web services utilization for personal or organizational needs. However the users of web service are yet facing challenges to find the desired web service due to rapid growth of web services available on internet. There is a need of a strategy to locate web services with issues covering like performance, flexibility and reliability across multiple heterogeneous registries, which is a challenging task yet. Our proposed framework covers these issues; it actively obtains user required web service by crawling among different repositories. Google Custom Search API is used for this purpose. Verification and validation checks are performed to confirm that the retrieved document is a web service and is currently available. One use of Web Services in computer applications is its automated Composition. Our framework presents a Service Composition through user interaction. To resolve compositional complexity parameters matchmaking is performed. Overall the framework provides a reliable and trustworthy composition.
