Abstract：A correlation is usually exist between speaker’s sentiment and act in daily dialogs, which could also be reflected in the dialogue structure. Therefore, we propose a joint model to classify the sentiment and act in each utterance by using the dialog structure. Moreover, we use the attention mechanism to capture the impact of the structure of dialog on the sentiment of each utterance. Experiments show that the proposed model outperforms the state-of-the-art models in both dialog sentiment classification and act classification.
