Arguman.org is an open source argument mapping platform which was developed by an avid community started in Turkey and spread to the world. It provides a visual critical thinking discussion platform written in python / django and used various open source libraries for various features. Arguman has 500+ commits and 24+ developer and more non-developer contributers. For the last couple months, the community is working on building a semantic network between arguments and calculating the objection and supporting rate of arguments.
