Our ECIR 2015 paper on multi-emotion detection in user-generated reviews by Lars Buitinck, Jesse van Amerongen, Ed Tan and Maarten de Rijke is online now.

Expressions of emotion abound in user-generated content, whether it be in blogs, reviews, or on social media. Much work has been devoted to detecting and classifying these emotions, but little of it has acknowledged the fact that emotionally charged text may express multiple emotions at the same time. We describe a new dataset of user-generated movie reviews annotated for emotional expressions, and experimentally validate two algorithms that can detect multiple emotions in each sentence of these reviews.
