Previous research on affective analysis focuses on text modality (Liu and Zhang, 2012;Cambria and Hussain, 2015), which is a hot research topic in the NLP community.
recent research suggests that information from text is not sufficient for mining opinion of humans (Poria et al., 2017a;D'Mello and Kory, 2015;Cambria, 2016), espe-cially under the situation where sarcasm or ambiguity occurs.
