  We convert the Chinese medical text attributes extraction task into a
sequence tagging or machine reading comprehension task. Based on BERT
pre-trained models, we have not only tried the widely used LSTM-CRF sequence
tagging model, but also other sequence models, such as CNN, UCNN, WaveNet,
SelfAttention, etc, which reaches similar performance as LSTM+CRF. This sheds a
light on the traditional sequence tagging models. Since the aspect of emphasis
for different sequence tagging models varies substantially, ensembling these
models adds diversity to the final system. By doing so, our system achieves
good performance on the task of Chinese medical text attributes extraction
(subtask 2 of CCKS 2019 task 1).
