Table 5: Performance on MSRA.
['Models', 'P', 'R', 'F1']
The word-based methods were built on the automatic segmentation results generated by the segmenter trained on training data of MSRA. Compared methods included the best statistical models on this data set, which leveraged rich handcrafted features Chen et al. ; Zhang et al. et al. Dong et al. From the table, we observe that our method obtained a statistically significant improvement over Lattice-LSTM and other comparative baselines on the recall and F1-score, verifying the effectiveness of our method on this data set.
