【Abstract】 In order to solve the problem that SMD(Schema Matching using Duplicates)algorithm can not deal with the case that some attributes have matching relations but their values do not have duplicates, we propose the integrated schema matching algorithm based on duplicates(ISMD),by adding the processing of the attributes which are similar or opaque and the value which are non-interpreted or have the same domain scale to find integrated matching attribute pairs. Our method not only improves the precision, but also increases the automatization of schema matching.更多还原
