This procedure identified the same four significant differences in Accuracy as in Table 4-namely, SUMTIME is significantly better than all systems except pCRU-greedy and Template.
it identified only three significant differences in Claritynamely, SUMTIME is significantly better than Template and pCRU-random, and pCRUgreedy is better than pCRU-random (this is a subset of the significant differences in Clarity shown in Table 4).
