ParityBOT is a chatbot developed here in Edmonton that tweets positive things about women in politics in response to hateful tweets. It send empowering messages.
You can read about it in a CBC story, Engineered-in-Edmonton Twitter bot combats misogyny on the campaign trail.
The bot follows all women candidates in the election and uses some sort of AI or sentiment detection to identify nasty tweets aimed at them and then responds with a positive message from a collection crowdsources from the public. What isn’t clear is if the positive message is sent to the offending tweeter or just posted generally?
ParityBOT was developed by ParityYEG which is a collaboration between the Alberta Machine Intelligence Institute and scientist Kory Mathewson.
