Abstract: Web service is one of the key technologies of SOA (service-oriented architecture) solution. How to improve the quality of annotations of Web services is becoming more and more important. Traditional annotation methods commonly have the drawbacks of low annotation quality and lots of manual intervention. For the limitation of ontology size, many keywords cannot be annotated with relevant concepts. The Web service annotation system based on user interaction includes a threshold selection algorithm with user?s feedback, an algorithm to expand the corresponding ontology and an annotation method with user?s interaction. The system automatically modifies relevant annotations with the feedbacks and records the modification results for relevant annotations in the future. In order to maximize the influence of feedbacks, some indicators with which the most informative annotation results will be chosen for confirmation are defined. For the shortage of ontology concepts, two methods for expanding the ontology are proposed, including learning a local ontology and the inquiry of online ontology. At last, this paper introduces the experiments which show that the quality of annotation is significantly improved after the interaction.
