Traditionally in NLP, sentiment analysis aims to identify the opinion or sentiment of the speaker (writer) toward a certain topic. The increasing availability of massive written tidbits of people everyday life enables the large-scale measurement of people's mood. Peter Sheridan Dodds and Christopher M. Danforth suggested a very simple way to measure happiness from written texts^1. This method was used in Twittermood and several other researches^2. Facebook is also doing similar measurements[^3][^4]. Positive/negative dichotomy is probably too simplistic[^5].
Regarding Homophily and influence, it was shown that the assortativity of happiness can be measured in online social networks[^6][^7].

How does sentiment analysis differentiate different domains[^8]?
