论文摘要
语义角色标签主要用于识别谓词,论证及其语义关系。由于建模方法的局限性以及预识别的谓词的条件,先前的工作集中在谓词和参数之间的关系以及最多最多参数之间的相关性,而谓词之间的相关性很长一段时间。高阶特征和结构学习在建模神经网络时代之前非常普遍。在本文中,我们引入了神经语义角色标记模型的高阶图结构,该模型使该模型不仅能够明确考虑孤立的谓词对题材对,而且还可以考虑谓词对题材对之间的相互作用。 CONLL-2009基准的7种语言的实验结果表明,高阶结构学习技术对出色的性能SRL模型有益,并进一步提高了我们的基线以实现新的最新结果。
Semantic role labeling is primarily used to identify predicates, arguments, and their semantic relationships. Due to the limitations of modeling methods and the conditions of pre-identified predicates, previous work has focused on the relationships between predicates and arguments and the correlations between arguments at most, while the correlations between predicates have been neglected for a long time. High-order features and structure learning were very common in modeling such correlations before the neural network era. In this paper, we introduce a high-order graph structure for the neural semantic role labeling model, which enables the model to explicitly consider not only the isolated predicate-argument pairs but also the interaction between the predicate-argument pairs. Experimental results on 7 languages of the CoNLL-2009 benchmark show that the high-order structural learning techniques are beneficial to the strong performing SRL models and further boost our baseline to achieve new state-of-the-art results.
