Argument component detection (ACD) is an important sub-task in argumentation mining. ACD aims at detecting and classifying different argument components in natural language texts. Historical annotations (HAs) are important features the human annotators consider when they manually perform the ACD task. However, HAs are largely ignored by existing automatic ACD techniques. Reinforcement learning (RL) has proven to be an effective method for using HAs in some natural language processing tasks. In this work, we propose a RL-based ACD technique, and evaluate its performance on two well-annotated corpora. Results suggest that, in terms of classification accuracy, HAs-augmented RL outperforms plain RL by at most 17.85%, and outperforms the state-of-the-art supervised learning algorithm by at most 11.94%.

我们提出了一个神经架构建模的争论性对话,明确建模意见持有者的(OH的)推理和挑战者的论点之间的相互作用,预测的目标,如果参数成功地改变了OH的看法。该模型有两个组成部分:(1)脆弱区域检测,一个注意力模型,它识别OH的推理中易于改变的部分,以及(2)交互编码,它识别OH的推理内容与挑战者的论点内容之间的关系。根据Reddit上Change My View论坛的讨论评估,这两个组件共同预测OH的视图变化,表现优于几个基线。事后分析表明,由注意力模型挑选出来的句子更容易被成功的论点所解决,而不是不成功的论点。
