Abstract
Top-k queries in XML involves retrieving approximate matching XML documents. Existing techniques process top-k queries in XML by applying one or more relaxations on the twig query. In this work, we investigate how Prüfer sequence can be utilized to process top-k queries in XML. We design a method called XPRAM that incorporates the relaxations into the sequence matching process. Experiment results indicate that the proposed approach is efficient and scalable.
