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. © 2009 Springer Berlin Heidelberg.||Source Title:||Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)||URI:||http://scholarbank.nus.edu.sg/handle/10635/40548||ISBN:||3642035728||ISSN:||03029743||DOI:||10.1007/978-3-642-03573-9_29|
