Emotion Detection from Text using Fuzzy Logic

Abstract

In this paper we propose to use fuzzy logic in detecting emotional content from text. Fuzzy logic was developed to deal with concepts that do not have well-defined, sharp boundaries, which theoretically is ideal for emotion as no well-defined boundaries are defined for emotion categories (e.g., happiness, sadness, surprise, fear, disgust, and anger).The transition from one physiological state of emotion to another is also gradual and could easily be modeled by fuzzy logic approach.
