We follow the official evaluation from the SemEval shared task for frame-semantic parsing Baker et al. Our semi-CRF baseline outperforms all prior work, without any syntax. This highlights the benefits of modeling spans and of global normalization. Contemporaneously with this work, Peng et al. We evaluated their output for argument identification only; our semi-CRF baseline model exceeds their performance by 1 F1, and our common nonterminal scaffold by 3.1 F1.
