Abstract: In order to realize function matching of Web services,an input and output-based function matching method was proposed based on extension and supplements of existing studies. In the method,inputs & outputs were clearly defined,and the definitions were combined with sub-processes constituting Web services. According to the contents and representation methods of the inputs and outputs,a matching strategy that combined the grouping by parameters types with the layering by names,values or enumerated domain was proposed in the method,which could improve the matching constringency speed. Subsequently,four function matching degrees,including exact matching,inclusive matching,partial matching and no matching,were given based on analysis of semantic and logic relationships of input & output. Also the corresponding judgment rules were provided. Moreover,a function matching process was discussed and constructed. Finally,an example was given to verify the proposed method,judgment rules and process.
