About

As a part of researching social-cognitive development of humans, Prof. Dr. Moritz Daum, Dr. Stephanie Wermelinger and their team at the University of Zurich are researching multilingual development in children. To improve the efficiency of gathering the necessary data, they needed a tool that could help them with this task.

Resulting from this need, the idea of Quassel was created. Collaborating closely with the University of Zurich, openscript Ltd. brought the software to life and is now being used by the name LEMON in the research project.

If you are interested in using the software for your own research project, feel free to reach out to the respective contact people. Quassel itself is an open-source project and can be found on GitHub.
