We substantiate our claim that PyPlutchik outperforms other classic visualisations when displaying Plutchik emotions and we showcase a few examples that display our module's most compelling features. Psychologist Robert Plutchik developed one of the most popular emotion wheels, known as the Plutchik wheel. Emotions with no colour depict a combination. The darker the shade, the more intense the emotion. The intensity of emotion decreases as we move outward and vice versa. ![]() ![]() Real-time affect detection in virtual reality: a technique based on a. The Moral Injury Experience Wheel: An Instrument for Identifying Moral. He created the wheel of emotions which shows various relationships among the emotions. 1980 Emotion: A psychoevolutionary synthesis. Notably, PyPlutchik allows users to display also primary, secondary, tertiary and opposite dyads in a compact, intuitive way. In the 20th century, Paul Ekman identified six basic emotions (anger, disgust, fear, happiness, sadness, and surprise) and Robert Plutchik eight, which he grouped into four pairs of polar. Plutchik’s stated that there are 8 basic emotions. PyPlutchik draws the Plutchik's flower with each emotion petal sized after how much that emotion is detected or annotated in the corpus, also representing three degrees of intensity for each of them. For any enquiry about usage or installation feel free to contact the corresponding author, a Python module specifically designed for the visualisation of Plutchik's emotions in texts or in corpora. We introduce PyPlutchik the Pyplutchik package is available as a Github repository () or through the installation commands pip or conda. The most common layouts fail to preserve both features, not to mention the need of visually allowing comparisons between different corpora in a blink of an eye, that is hard with basic design solutions. The Geneva Emotion Wheel plots emotions in a wheel shape but on a grid of four quadrants that ranks them from pleasant to unpleasant and controllable to uncontrollable. The classic representation of the Plutchik's wheel follows the principles of proximity and opposition between pairs of emotions: spatial proximity in this model is also a semantic proximity, as adjacent emotions elicit a complex emotion (a primary dyad) when triggered together spatial opposition is a semantic opposition as well, as positive emotions are opposite to negative emotions. Visualisation of such emotions is traditionally carried out using the most popular layouts, as bar plots or tables, which are however sub-optimal. ![]() In it, Plutchik proposed eight basic emotionsjoy, sadness, trust, disgust, fear, anger, surprise, and anticipationwhich he believed overlapped and bled into the next like hues on a color wheel. Related researches range from annotation tasks description to emotions detection tools. One of the most prominent theories of the 20th century is Robert Plutchiks wheel of emotions. The increasing availability of textual corpora and data fetched from social networks is fuelling a huge production of works based on the model proposed by psychologist Robert Plutchik, often referred simply as the "Plutchik Wheel". Human emotion models such as the emotion wheel by Plutchik 1 or the universal emotion theory by Ekman 2 typically describe a fundamental set of emotions 9,10,11 along with composition rules.
