Classifying stance expressed in a text toward specific target is an emerging problem in opinion mining. A major difference between stance detection and traditional aspect-level sentiment classification is that the target of the stance might not be explicitly mentioned in text. In this paper, we show that the stance polarity of a text is not merely dependent on the content but is also highly determined by the concerned target. To this end, We propose a neural network based model, which incorporate target-specific information into stance classification using a novel attention mechanism. The proposed attention mechanism can focus on critical parts of a text. We evaluate our model on the SemEval 2016 Task 6 Twitter Stance Detection corpus achieving satisfactory performance. Our model achieves significant and consistent improvements on this task as compared with baselines.
