Comparison of Web Service Retrieval with Syntactic and Semantic Approach Using Similarity Measures

Web Service is a client server application that can communicate over an HTTP protocol and it provides interoperability between the applications which can be run on the different platforms. Web Service Discovery is to find the suitable Web Service for a user given query. Parser extracts the words from the Web Service Description. Then match the user query with the semantic Web Service Descriptions given in Web Service Modeling Ontology Language (WSML) file. Part-of-speech tagging is applied to find the nouns, verb and adverbs for the words extracted from the Web Service descriptions. WordNet tool is used to discover the synonym and semantic relation for each word in the user query and the Web Service description then the corresponding senses are determined. Words will have multiple meanings. Word sense Disambiguation is used to identify the correct context for the given user query. After finding the senses of suitable words gathered from web service descriptions and from the user query, sense matching will takes place which results in a list of relevant web services.SSI algorithm performs better and list the suitable web service.
