Table 4 shows the comparison between our approach and the one by<cite> Angeli and Uszkoreit (2013)</cite> . We outperform their approach not only with respect to the accuracy but also with respect to the numbers of correctly normalized expressions (574 vs. 484 5 and 121 vs. 86 5 on the training and test sets, respectively) -despite the fact that we perform the full task of temporal tagging and not only the normalization.
