NER: Chinese Named Entity Recognition in Keras

Model1：Character_embedding-Based BiLSTM-CRF.
Model2：On the basis of model1. Extract n_gram feature from word embedding as auxiliary feature, using Conv1D.

Ps：
Run preprocess.py and utils.py firstly, to get processed train/dev/test data and pre-trained char/word embedding matrix.
The file 'appendix_···.py' is writed by means of 'BosonNLP'.
