XML model capture more semantic information and navigates into document and display more relevant information. The keyword search is alternative method to search in XML data, which is easy to use, user doesn’t need to know about the XML data and query language. In this paper focus on the techniques used to retrieve the top-k result from the XML document more efficiently. Top-k relevant answer identify examine effective ranking function and early termination techniques achieves high search efficiency and result quality.
