The invention relates to a descriptive information matching similarity-based resource service matching and searching method. Specifically, in the method, after digital manufacture resource service description, resource service descriptive information is further divided into types of character body concept, sentence, digital value, entity concept and the like, and corresponding similarity matching algorithms are designed respectively; and on such a basis, resource service matching searching is realized by the steps of basic matching, input and output matching, quality of service matching and comprehensive matching. The method mainly aims to solve the problem that the matching and searching of the descriptive information types of the digital value, sentence, entity concept and the like are not taken into account in the conventional resource service matching. In the method, a manufacture resource service matching and searching realization frame, the similarity matching algorithm for the different types of service descriptive information, a multilayer resource service matching model and realization algorithms are involved. The method has the advantage that: a distributed system supporting semantics and SOA is hierarchically clear and has high compatibility and expansibility.
