Research On Matching Method For XML Schema

With the increasingly development of XML, more data is represented by the format of XML, which has been a default standard for Web data representation and exchange. Such as the E-commercial applications, If the two sides of exchange abide by the same schema criterion it will be easier to share resource and complete the integrate information between them. Currently, the most application of XML face the problem of disunity of the schema. It requires find the mapping relationship between the related elements in the two input schema. And then according to the mapping,one can be transformed into another.The first is to study the approaches of the schema matching. A schema matching algorithm is presented by analyzing the existing methods. And then, aiming at research on transform between two heterogeneous documents.The similarity of two elements depends on two similarity, element level similarity and structural similarity, and the computing method of the structural similarity has been improved. The method consists of two steps, computing preliminary matching relationships between elements in the two XML schemas, getting proposed context similarity and extracting final matches based on compositeness of two.In the solution of the transforming between two XML documents, the semantic mapping relationship between two schema elements can be found by using the proposed algorithm. And then according to the result of matching, create the XSLT stylesheet file.
