Ontology Based Semantic Web Service Discovery and Composition Framework

Web Service Discovery is the process of finding a suitable Web Service for a given task. A theoretical analysis of ontology-based service composition is proposed in terms of its dependency with service discovery. Web Service composition technique provides the features to users that an individual web service cannot perform. At service composition time, the composition of service depends on the users input outputs parameters and other non-functional parameters. In order to evaluate the best approach an optimal composition search algorithm to extract the best composition from the graph minimizing the length and the number of services and different graph optimizations to improve scalability of the system. The implementation of Floyd-Warshall algorithm can find all the possible way of services integrated and services to the web tasks. We have designed a full frame work for good integrated services for the particular tasks and given good performance of the web.
