A Semantic Search Engine For Web Service Discovery By Mapping Wsdl To Owl

Web services is a web based API which provides functionality over web to integrate within web based applications. In such systems, there is often a machine-readable description of the operations offered by the service written in XML based markup language called the Web Services Description Language. The WSDL contains description about how the service can be called, what parameters it expects, and what data structures it returns. This WSDL file will be accessed by the search engine for the process of service discovery. Web services annotation is redefined to enhance the services discovery mechanism by mapping it to semantic annotations (OWL-S). The ontology mapping engine search for the keyword relationship with the existing keywords kept in the local ontology base and creates an ontology keyword list. There will be situation in which the local ontology database may not have the set of keyword relations to form an ontology keyword list. For that propose a standardization engine to fetches ontology which are not present in the local ontology database. This process of mapping mainly relies on a local ontology repository which is standardized using the global ontology base and by applying Onto-Ranking. It helps to manage the resultant that we get from the discovery process in an unsorted manner.
