Overview of the TREC 2008 Blog Track

2008 Text Retrieval Conference  
The TREC distributed opinion-finding medians for each topic are computed over all runs (baselines + opinion-finding runs, i.e. 191+41 = 232 runs). We consider that including the baseline runs in the computation of the medians would be inappropriate, as these baseline runs were not intended to retrieve opinionated documents. In addition, when the number of runs is even (e.g. 232), TREC computes the "upper median".
