Before revision:  We test LTP on multiple datasets, and the experiments show that LTP performs  better than traditional strategies (incluing LC and NLC) on both token-level F_1 and sentence-level accuracy , especially in complex imbalanced datasets.
After revision:  We test LTP on multiple datasets, and the experiments show that LTP performs better than traditional strategies with obviously less annotation tokens on both sentence-level accuracy , especially in complex imbalanced datasets.
