First, the model trained on only edit logs (UDN-only) performs well on UDN Edit Logs but very poorly on SIGHAN-7.
the model trained on only artificially generated data (ART-only) has worst performance on UDN Edit Logs but acceptable performance on SIGHAN-7 Second, it is worth noting that the model trained with sound and shape features has significantly better accuracy, recall, and F1 score on UDN Edit Logs.
