Detecting and Visualizing Changes in Emotions in Texts

The project will develop methods and tools for automatically detecting the writers' feelings towards certain topics. A particular interest in this project is the detection of emotional changes from student texts whether they be essays, theses or students' web-based collaboration. Analyzing the emotional contents of texts and monitoring and predicting potential conflict situations automatically offers an opportunity to fight against the potential negative impacts brought about by online technologies. The project will also develop tools for visualizing emotional states and their changes in texts. In addition to the educational technology research group in Joensuu, an interdisciplinary and international network of collaborators from South Africa, China, Sweden, Finland and Austria will contribute to the project.
