Abstract

This paper presents an overview of the Efficiency Track that was run for the second time in 2009. This track is intended to provide a common forum for the evaluation of both the effectiveness and efficiency of XML ranked retrieval approaches on real data and real queries. The Efficiency Track significantly extends the Ad-Hoc Track by systematically investigating different types of queries and retrieval scenarios, such as classic ad-hoc search, high-dimensional query expansion settings, and queries with a deeply nested structure (with all topics being available in both the NEXI-style CO and CAS formulations, as well as in their XPath 2.0 Full-Text counterparts). The track received 68 runs submitted by 4 participating groups using 5 different systems. The best systems achieved interactive retrieval times for ad-hoc search, with a result quality comparable to the best runs in the AdHoc track.
