摘要：Web searching is becoming more and more complex due to increased size of information on the web. Users have to face a lot of problems in specifying their needs in the form of query. Query Reformulation techniques are required in order to provide users with the results, according to their expectations. The existing reformulation techniques suffer from the problem of not providing users with expected results in all the cases because the mechanisms used behind those techniques are not much fine and accurate. A technique for query reformulation has been presented in this paper which is based on Cross Document Structure Theory (CST) and Rhetorical Structure Theory (RST). A case study has been carried out to validate the proposed technique. The results are satisfactory as set of reformulated queries generated through this technique is semantically more close to the original query which ultimately provides more relevant data to the user.
