Semantic web services promises the combination of semantic web with web service technology in order to overcome the limitations of current web services by adding explicit semantics to them. Semantic web service technology is to improve the machine to machine interaction via web 3.0. It also aims to describe the web service and its functionalities clearly which facilitates the discovery of services efficiently. Due to the evolution of the technology, the annotations for web service are semantically defined using the OWL instead of WSDL. Semantic annotation of web services capabilities with ontological information aims at providing the necessary infrastructure for facilitating efficient and accurate service discovery.
