For semantic frame induction, words must be grouped according to the frames that they evoke, and their arguments must also be grouped according to the frame element roles that they fill. In this paper, we address the latter task of argument clustering to acquire frame element knowledge, and we propose a method that applies deep metric learning. In this method, a pre-trained language model is fine-tuned to be suitable for distinguishing frame element roles through the use of frame-annotated data, and argument clustering is performed based on embeddings obtained from the fine-tuned model. Experimental results on FrameNet demonstrate that our method achieves substantially better performance than existing methods.
