Example text

Seven teams, we selected the official “best” run in terms of Mean D -nDCG@10, as shown in the right half of Table 3. Then we applied a randomised version of two-sided Tukey’s Honestly Significant Differences (HSD) test as described by Carterette [4] for the three evaluation metrics with different settings. Table 4 shows the results. e. pd = 40) relevance assessments are used. Thus, assuming that less incomplete assessments provide more reliable conclusions, the significant difference in terms of D-nDCG@10 is a false alarm.

Row 6 is our proposed method. There are some clear trends in the results of Table 2: 1. Unigram language model using Dirichlet Smoothing significantly outperforms that using JM smoothing in the setting of our experiments (Row 1 vs. Row 2). 2. The method retrieving in the optimal category that specified to the queried question by users of Yahoo! Answers does not improve the methods without considering the category information (Row 3 vs. Row1, 2). The results show that the queried question’s category information does not help the retrieval performance when used directly and this is consistent with the former work [3, 2].
