Analyzing Distribution of Implicit Semantic Information in Web Services

Semantic annotation for Web services represents an important approach that transforms Web services into Semantic Web services. This paper analyzes the distribution of implicit semantic information to enhance the understanding about Web services. After quantifying implicit semantic information in Web services, the PCA methodology is utilized for obtaining principal components of implicit semantic information. The experiment conducted on 11836 WSDL documentations shows that almost 97 percent of implicit semantic information is distributed in inputs and outputs. Thus, the evaluation of how much implicit semantic information can be described by semantic annotation is offered.
