Choosing an Ideal Recall-Base for the Evaluation of the Focused Task: Sensitivity Analysis of the XCn of the Focused task is affected when different methodology is employed in generating the so-called ideal recall-base, which forms the ground-truth of the evaluation. The results show that the choice of methodology can impact on the obtained performance scores and the relative ranking of systems in

Filtering and Clustering XML Retrieval Resultseval engine retrieves arbitrary elements from the collection (corresponding to the Thorough Task). These runs are filtered to remove textual overlap between elements (corresponding to the Focused Task). The resulting runs can be clustered per article (corresponding to the All in Context Task).
