摘要:

姿态分类确定(通常为短)文本中的姿态或姿态。该任务具有强大的应用程序,例如检测假新闻或自动提取对媒体中实体或事件的态度。本文描述了一个令人惊讶的简单和有效的分类方法,在Twitter的开放立场分类,谣言和准确性分类。该方法得益于一组新的自动识别问题特定特征,这些特征显著提高了分类器的准确性,并在最近的基准数据集上实现了上述最先进的结果。这就质疑了在没有首先进行知情的特征提取的情况下使用复杂的复杂模型进行立场分类的价值。

英文摘要:

Stance classification determines the attitude, or stance, in a (typically short) text. The task has powerful applications, such as the detection of fake news or the automatic extraction of attitudes toward entities or events in the media. This paper describes a surprisingly simple and efficient classification approach to open stance classification in Twitter, for rumour and veracity classification. The approach profits from a novel set of automatically identifiable problem-specific features, which significantly boost classifier accuracy and achieve above state-of-the-art results on recent benchmark datasets. This calls into question the value of using complex sophisticated models for stance classification without first doing informed feature extraction.
