摘要:

论证成分检测是论证挖掘中的一个重要子任务。ACD的目标是检测和分类自然语言文本中的不同论点成分。历史注释(HA)是注释人员在手动执行ACD任务时考虑的重要功能。然而,HA在很大程度上被现有的自动ACD技术所忽略。强化学习(RL)已被证明是在某些自然语言处理任务中使用HA的有效方法。在这项工作中,我们提出了一个基于RL的ACD技术,并评估其性能上两个良好的注释语料库。结果表明,在分类精度方面,HAS增强的RL优于普通RL最多17.85%,优于最先进的监督学习算法最多11.94%。

英文摘要:

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%.
