Abstract
Developing features has been shown crucial
to advancing the state-of-the-art in Semantic Role Labeling (SRL).
To improve Chinese SRL, we propose a set of additional features, some of which are designed
to better capture structural information.
Our system achieves 93.49 F-measure, a significant improvement over the best reported performance 92.0.
We are further concerned with the effect of parsing in Chinese SRL.
We empirically analyze the two-fold effect, grouping words into
constituents and providing syntactic information. We also give some preliminary linguistic explanations.
