Abstract: The quantity of XML data shared in the World Wide Web is increasing quickly and it offers both challenges and opportunities in information retrieval, data mining and intelligent information processing. As the basis of information retrieval, mining, and processing, accurate determination of similarity between XML documents is important and valuable. This paper provides a novel recursive method to get the similarity between XML documents according to the semantic and structural features of XML. It also provides experiments to show the comparison of the method against traditional methods and the results prove the method is highly effective.
