Example text

This suggests that element-level or passage-level evidence is still valuable for article retrieval. When comparing the system rankings in terms of article retrieval with the system rankings in terms of the ad hoc retrieval tasks, over the exact same topic set, we see a reasonable correlation especially for the two “in context” tasks. The systems with the best performance for the ad hoc tasks, also tend to have the best article rankings. Since finding the relevant articles can be considered a prerequisite for XML-IR, this should not come as a surprize.

BEP, including correlation, tag set membership, physical location and combinations of these factors [4]. For 2007, best results were obtained based purely on physical position. 1729, based on RiC input, was generated; this value would appear at rank 10 in the 2007 rankings. 1722) was produced by a combination of two factors (tag set membership and location). In 2008, our experiments with BEP were based purely on physical location; they use the name tag as BEP. 1875 (which would rank at 9 in the 2008 rankings).

They have only one run in common, although they agree on five of the ten participants. Looking, more formally, at the system rank correlations between the two types of article retrieval we see the following. 357. 356. 366. 388. Hence the judged topics above and the topics derived from the proxy log vary considerable. 8 on average for the proxy log topics. 7 Discussion and Conclusions In this paper we provided an overview of the INEX 2008 Ad Hoc Track that contained three tasks: For the Focused Task a ranked-list of non-overlapping results (elements or passages) was required.
