Handling Dislocated and Discontinuous Constituents in Chinese Semantic Role Labeling

This paper discusses two outstanding issues, dislocated and discontinuous arguments, in the construction of the Penn Chinese PropBank, a corpus that has already been treebanked. It describes the verbspecific approach in our semantic role annotation in which arguments and adjuncts are treated differently in the sense that arguments are assigned labels that are interpretable only within the scope of the verb while adjuncts receive labels that reflect a more global classification. The paper discusses the rationale behind this approach in comparison with other semantic role labeling projects.
