Abstract
Frame identification is a crucial and challenging task in frame semantic parsing, where the objective is to determine the most appropriate frame for a given target within its context. Existing approaches typically classify each target individually, overlooking the potential interactions among different targets. To address these limitations, we propose a novel two-step prediction framework that encompasses both local and global perspectives for target identification. Additionally, we leverage the frame ontology graph to enhance the interactions among multiple targets by incorporating rich frame ontology knowledge. Moreover, we introduce a dynamic masking strategy during model training. This strategy encourages our model to adopt a global view during prediction, avoiding local optimization. Experimental results demonstrate the superiority of our model compared to previous approaches on FrameNet1.5, and it achieves competitive performance on FrameNet1.7. Furthermore, supplementary experiments and analyses provide additional evidence of the effectiveness of our proposed model.
