Abstract: Emotion detection is a challenging NLP task as textual data is missing facial expressions or audio streams which are usually direct representations of emotions. However, textual data is still reach in terms of the emotional content. Current approaches to emotion detection in NLP rely on sentiment analysis, which falls short when it comes to detecting different emotions from a given text. In this talk, we will review the shortcomings of traditional approaches to emotion detection and introduce our novel approach which uses Natural Language Inference.
