Model service discovery algorithm based on semantics

Model service discovery, according to the requirements and restrictions on function and non-function for target service of the user, finds model service satisfying requirement and restriction of user from service registry through service discovery algorithm. Based on analyzing the traditional service discovery algorithm, this paper brings forward the model service discovery algorithm based on domain ontology and WordNet, which makes up the disadvantage of service discovery algorithm based on domain ontology or lexical ontology so as to efficiently improve the recall ratio and precision ratio of model service discovery.
