P-Stance: A Large Dataset for Stance Detection in Political Domain

Stance detection determines whether the author of a text is in favor of, against or neutral to a specific target and provides valuable insights into important events such as presidential election. However, progress on stance detection has been hampered by the absence of large annotated datasets. In this paper, we present P-STANCE, a large stance detection dataset in the political domain, which contains 21,574 labeled tweets. We provide a detailed description of the newly created dataset and develop deep learning models on it. Our best model achieves a macro-average F1-score of 80.53%, which we improve further by using semi-supervised learning. Moreover, our P-STANCE dataset can facilitate research in the fields of cross-domain stance detection such as cross-target stance detection where a classifier is adapted from a different but related target. We publicly release our dataset and code. 1
