I build a graph-based argument mapping system with community moderation with a friend as our CS master theses: https://github.com/woost/wust

I'm happy to discuss this whole topic with interested people, as I think it is a very important problem. I believe it may be possible in the long-term to fix politics with these kinds of technology. I wanted to do my PhD in this area, but wasn't able to get any funding. So I'm starting a Startup now, that does graph-based collaboration software (with the future hope to bring more focus into arugment mapping): https://app.woost.space

If interested, I can also send you my master thesis, just reach out per email.
