TL;DR
PyPlutchik is a Python library that visually represents emotions in texts based on Plutchik's model, enabling intuitive comparison of emotion-annotated corpora with enhanced clarity over traditional methods.
Contribution
The paper introduces PyPlutchik, a novel visualization tool that accurately depicts Plutchik's emotion model, including intensity and dyads, improving upon existing visualization techniques.
Findings
PyPlutchik effectively visualizes emotion intensity and relationships.
It outperforms traditional visualizations in clarity and comparison.
The library supports detailed emotion analysis in corpora.
Abstract
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''. Related researches range from annotation tasks description to emotions detection tools. Visualisation of such emotions is traditionally carried out using the most popular layouts, as bar plots or tables, which are however sub-optimal. 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. The most common layouts fail to preserve…
