Research on XML semantic retrieval
MO Zhengb · Computer Engineering and Applications Journal · 2013
With more and more application of semi-structure data, the research of XML document similarity becomes essential in the database and information retrieval communities. Given set of XML documents D and the user query q, XML retrieval is to find out the XML documents from the D which satisfies q. In order to search efficiently, a new approach is presented to calculate similarity between two XML documents. The approach is divided into three steps. The user's query q is expanded to q' by including the synonyms of q based on WordNet. q' and each XML document in D are allocated to digital signatures. After eliminating the irrelevant documents in D according to the signatures matching, a subset D' of D is got. Precise matching between q and D'is presented and final results are got.
