Almost all automatic semantic role label- ing (SRL) systems rely on a preliminary parsing step that derives a syntactic struc- ture from the sentence being analyzed. This makes the choice of syntactic repre- sentation an essential design decision. In this paper, we study the influence of syn- tactic representation on the performance of SRL systems. Specifically, we com- pare constituent-based and dependency- based representations for SRL of English in the FrameNet paradigm. Contrary to previous claims, our results demonstrate that the systems based on de- pendencies perform roughly as well as those based on constituents: For the ar- gument classification task, dependency- based systems perform slightly higher on average, while the opposite holds for the argument identification task.
