Abstract  

[Objective] This paper proposes an Emotional Dilation Gated CNN (EDGCNN) model, aiming to extract emotion-cause pairs for sentiment analysis. [Methods] First, we used the emotional discriminant model to identify sentiment sentences. Then, we input coding for these sentences to the EDGCNN model and located corresponding reasons. Finally, we tagged keywords of reasons generated from the experimental dataset. [Results] The new model’s recall and F1 values reached 63.52% and 60.45% respectively on the training dataset, which were better or very similiar to the existing ones The proposed model also extracted emotion-cause pairs at finergranularity level. [Limitations] The experimental corpus size was small. [Conclusions] The proposed model can extract emotion-cause pairs effectively.
