Predicate sense disambiguation. The predicate sense disambiguation subtask applies only to the CoNLL 2009 benchmark. In this line of research on dependency-based SRL, previous papers seldom report the accuracy of predicate disambiguation separately (results are often mixed with argument identification and classification), causing difficulty in determining the source of gains. The state-of-the-art model He et al. Instead of using linguistic features, our simple MLP model achieves better accuracy with the help of powerful contextual embeddings. These predicate sense disambiguation results are used in the dependency-based SRL end-to-end evaluation.
