Example text

The average distances of the first relevant passage from the document start measured in characters by topic with optimal, average and realistic document retrieval scenarios. The topics are sorted according to the distance for each scenario. Note the logarithmic scale. 4 Discussion and Conclusions The focused retrieval strategy is not beneficial, if a result document is densely relevant or the relevant content is located in the document start. Therefore, this study aimed to motivate the RiC task by analyzing the relevance densities and the locations of the relevant material in the relevant result documents.

For the Relevant in Context Task, we see that the top run is significantly better than ranks 2 through 10. The second best run is significantly better than ranks 4 through 10. The third run better than ranks 6–10, the fourth run better than ranks 5-10, the fifth run better than runs 6 and 9–10, the sixth through eighth run better than runs Overview of the INEX 2010 Ad Hoc Track 23 Table 11. 0634 9–10.
