Table 2 shows the statistics of the expanded relevance assessments thus obtained.
When a new run is evaluated with a condensed-list metric, many relevant documents go up the ranks as the unjudged documents in the run are removed. The above work of Sakai generalises an earlier ﬁnding by B¨ uttcher et al. who focussed on binary relevance metrics such as Average Precision (AP) and Binary Preference (bpref): “Where AP underestimates the performance of a [new] system, bpref overestimates it” . However, these studies were about traditional IR, where typically pd = 100 and l = 1000.
