An event occurring in a particular geographic region is identified based on disseminated information containing public commentary in the particular geographic region.

A sentiment trend visualization is generated that depicts a trend of sentiments of at least a particular one of the identified attributes, wherein the sentiments are based on the sentiment words for at least the particular attribute.
