提醒用户,一个网页是有争议的已被提出作为一种方法,以支持批判性思维的文本和话语。我们提出了一种方法来发现有争议的话题,在一个通用的文件,使用无监督训练。我们的方法包括迭代训练的争议分类器使用的意见和解释争议的文件中产生的主题短语描述it.Experiments表明我们提出的训练方法使用EM算法的有效性。当有争议的主题提取仅限于高质量的短语并结合TextRank信号时,它优于几种基线方法。
Alerting users that a web page is controversial has been proposed as one method to support critical thinking about text and discourse. We propose an approach to discover controversial topics in a generic document using unsupervised training. Our approach comprises iterative training of a controversy classifier using a disagreement signal within comments and explaining the controversy of the document by generating a topic phrase describing it. Experiments show the effectiveness of our proposed training method using an EM algorithm. When controversial topic extraction is restricted to quality phrases and incorporates TextRank signals, it outperforms several baseline approaches.
