Before revision:  On the other hand, IC progressively strengthens the model's ability in identifying the mismatched information between the dialogue context and response . Empirical studies on two benchmark datasets with three state-of-the-art matching models demonstrate that the proposed HCL significantly improves the model performance across various evaluation metrics.
