Simplify the Usage of Lexicon in Chinese NER
Table 8: F1-score with different implementations of the sequence modeling layer. ExSoftword is the shorthand of Char-based+bichar+ExSoftword.
['Model', 'OntoNotes', 'MSRA', 'Weibo', 'Resume']
From the table, we can first see that the LSTM-based architecture performed better than the CNN- and transformer- based architectures. In addition, our methods with different sequence modeling layers consistently outperformed their corresponding ExSoftword baselines. This shows that our method is applicable to different neural sequence modeling architectures for exploiting lexicon information.
