Abstract
One or more embodiments of techniques or systems for sentiment extraction are provided herein. From a corpus or group of social media data which includes one or more expressions pertaining to a topic, target topic, or a target, one or more candidate expressions may be extracted. Relationships between one or more pairs of candidate expressions may be identified or evaluated. For example, a consistency relationship or an inconsistency relationship between a pair may be determined. A root word database may include one or more root words which facilitate identification of candidate expressions. Among one or more of the root words may be seed words, which may be associated with a predetermined polarity. To this end, polarities may be determined based on a formulation which assigns polarities to a sentiment expression, candidate expressions, or an expression as a constrained optimization problem.
