Most of the previous work on predicate-argument(PA) structure analysis utilized pipeline strategies with several subtasks. However, when the subtasks are sequentially processed, the errors propagate from the preceding subtasks to consecutive subtasks. In this paper, the PA structure analysis is divided into three subtasks: predicate sense disambiguation, argument classification and argument identification. A dual decomposition method is used to join the latter two subtasks, which alleviates the… CONTINUE READING
