论文摘要
立场检测任务旨在对给定文件和主题的立场进行分类。由于这些主题可以隐含在文档中，而在零摄影设置的培训数据中看不见，因此我们建议通过使用情感和常识知识来提高立场检测模型的可传递性，这在先前的研究中很少被考虑。我们的模型包括一个图形自动编码器模块，以获取常识性知识和带有情感和常识的立场检测模块。实验结果表明，我们的模型优于零射门和少量基准数据集（VAST）上的最新方法。同时，消融研究证明了我们模型中每个模块的重要性。对情感，常识和立场之间关系的分析表明了情感和常识的有效性。
The stance detection task aims to classify the stance toward given documents and topics. Since the topics can be implicit in documents and unseen in training data for zero-shot settings, we propose to boost the transferability of the stance detection model by using sentiment and commonsense knowledge, which are seldom considered in previous studies. Our model includes a graph autoencoder module to obtain commonsense knowledge and a stance detection module with sentiment and commonsense. Experimental results show that our model outperforms the state-of-the-art methods on the zero-shot and few-shot benchmark dataset--VAST. Meanwhile, ablation studies prove the significance of each module in our model. Analysis of the relations between sentiment, common sense, and stance indicates the effectiveness of sentiment and common sense.
