19470553, corresponding to rank 6 of all runs; this is a good improvement over 2007, which we mainly attribute to the better performance of the new scoring function. To compute the best entry point for a document, we post-processed the RelevantInContext runs by simply selecting the element with highest score from each document and ordered them by score. 17081437, corresponding to rank 13 among all runs. 4 Conclusions and Future Work This paper presented a structure-aware proximity score for XML retrieval that helps to improve the retrieval effectiveness of gap-free approaches for article-level retrieval.

In many cases this behaviour is not the expected one, because probably a user who employs several terms to express his/her query is expecting to find most of these terms in the structural units obtained as the answer of the system to this query. For that reason we believe that it is interesting to define other utility models which give more importance (in a non-linear way) to the appearance of most of the terms in the query. In this work we propose a parametric non-linear utility model that, as the parameter grows, the more terms from the query must be contained in a structural unit in order to get a high utility value for this unit.

University of Amsterdam. Run retrieving FOL passages using the CO query. Description: language model with local indegree prior, setting the BEP always at the start of the article. Since the offset is always zero, this is similar to an article retrieval run. Based on the information from these and other participants – As for the Relevant in Context Task, we see again that solid article ranking is very important. In fact, we see runs putting the BEP at the start 18 J. Kamps et al. Table 9.
