In particular, we combine two complementary learning paradigms of NER, i.e., sequence labeling and span prediction, into a unified multi-task framework. After obtaining a sufficient NER model trained on the source data, we further train it on the target data in a {\\it dual-teaching} manner, in which the pseudo-labels for one task are constructed from the prediction of the other task.
