Before revision:  Experimental results on two Chinese SLU datasets show that our model can capture useful word information and achieve state-of-the-art performance . More importantly, our framework substantially gains further improvements when we plug the word adapters into a BERT, which again demonstrates the effectiveness and flexibility of our word adapter .
