Semantic Discovery of Web Services Based on Google Distance

To solve the problem that the most of the semantic Web service discovery algorithms required a domain ontology and had a high complexity,the Google distance was used to measure the semantic distance between input and output parameters of Web services,and based on Google's massive vocabulary and the Google searched engine to calculate the semantic similarity between services.This algorithm does not require domain ontology,computing matching degree of Web services based on the open search engine of Google.It can improve the computational efficiency and reduce the complexity of the algorithm.
