Query Biased Snippet Generation in XML Search yu.huang.1@asu.edu Arizona State University Yu Huang Arizona State University Ziyang Liu ziyang.liu@asu.edu Arizona State University Yi Chen yi@asu.edu ABSTRACT Snippets are used by almost every text search engine to complement ranking scheme in order to e ectively handle user searches, which are inherently ambiguous and whose relevance semantics are di cult to assess. Despite the fact that XML is a standard representation format of web data, research on generating result snippets for XML search remains untouched. In this paper we present a system, eXtract, which addresses this important yet open problem. We identify that a good XML result snippet should be a self-contained meaningful information unit of a small size that e ectively summarizes this query result and di erentiates it from others, according to which users can quickly assess the relevance of the query result. We have designed and implemented a novel algorithm to satisfy these requirements and veri ed its e ciency and e ectiveness through experiments.
