Development of Emotion-weather Maps

Emotion-weather maps are a type of thematic map used to represent emotions. The maps represent spatial distributions of complex emotions from a large group of people. Most related work focuses on a simple sentiment and draws its distributions on a map. The proposed emotion-weather maps are a set of eight maps, each of which represents one of eight categories of emotions. Emotion data are extracted from social media. The data have some biases in some aspect of time, space, and categories of emotions. Such biases restrict the observation of relatively few emotions. To address this problem, a method to normalize data is proposed. As a use case, two sets of maps are presented. These maps represent the distribution of emotions in an actual day. An earthquake on that day caused fear and surprise in a region of Japan. The maps show the emotion distributions and changes.
