A Web Service Discovery Method Based on Tag

With the growth of web service, traditional web service discovery mechanisms have become inefficient because of their low precision. Though the current semantic-based service discovery methods enhance the recall rate and precision in a way, most of the semantic-based service discovery methods are based on the new model of the semantic web and the ontology language, the number of the services based on the model of the semantic web and the ontology language is so little that these methods can not been used effectively. In this paper, we bring forward a new service discovery method based on the service tags. In order to discover service based on the services tags, we bring forward the algorithm QEBT and QPBT. Our experimental study shows that the algorithm QPBT is better than QEBT. Furthermore, both QEBT and QPBT are effective on discovering service.
