Abstract
Snippets are used by almost every text search engine to com-plement ranking scheme in order to effectively handle user searches, which are inherently ambiguous and whose rele-vance semantics are difficult to assess. Despite the fact that XML is a standard representation format of web data, re-search on generating result snippets for XML search remains untouched. In this paper we present a system, eXtract, which ad-dresses this important yet open problem. We identify that a good XML result snippet should be a self-contained mean-ingful information unit of a small size that effectively sum-marizes this query result and differentiates 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 verified its efficiency and effectiveness through experiments.
