Disaster events not only present a life safety hazard to persons or property, but also bring psychological trauma. Disparities in psychological perception exi-\st among different groups. Post disaster psychological intervention attracts more attention in recent years. In this paper, with the comments from the local communities toward the flood happened in Beijing on July 21, 2012, sentiment analysis and iView analysis are conducted to get the attitude of the communities in the flooding area. Such kind of exploratory research on communities perception after disasters is an expansion of traditional sociopsychological analysis and expected to provide help for societal management. Sentiment analysis shows that men are more positive in disaster than women, people at different ages or from different counties have different sentiment in disaster. We apply iView analysis to acquire the communities' opinion structure, which exhibits the advantages of qualitative meta-synthesis technologies toward behavioral data or first-hand information. The iView idea network shows opinions of residents experienced the disaster containing government assistance, post-disaster reconstruction, fear and so on. The iView human network shows that individuals are different in concerns.
