abstract
We present novel advancements in framesemantic parsing, specifically focusing on target identification and frame identification.Our target identification model employs a novel prefix tree modification to enable robust support for multi-word lexical units, resulting in a coverage of 99.4% of the targets in the FrameNet 1.7 fulltext annotations.It utilizes a RoBERTabased filter to achieve an F1 score of 0.775, surpassing the previous state-of-the-art solution by +0.012.For frame identification, we introduce a modification to the standard multiplechoice classification paradigm by incorporating additional negative frames for targets with limited candidate frames, resulting in a +0.014 accuracy improvement over the frame-only model of FIDO, the previous state-of-the-art system, and +0.002 over its full system.Our approach significantly enhances performance on rare frames, exhibiting an improvement of +0.044 over FIDO's accuracy on frames with 5 or fewer samples, and on under-utilized frames, with an improvement of +0.139 on targets with a single candidate frame.Overall, our contributions address critical challenges and advance the state-of-the-art in frame-semantic parsing.
