Matching Support Seekers with Support Providers and Responsible Decision Making with Knowledge-infused Bandits

Super Excited to share news on the acceptance of two research ideas:

• Matching Support Seekers with Support Providers
  • An automated method to identify supportive users is challenging due to diverse roles of users, but it is more challenging to #associate them with #supportseekers for suitable help.
  • Annotating such matches is exceptionally time consuming for experts and #moderators on online platforms. We demonstrate an expert validated methodology that uses #diverseknowledge to match support seekers and support providers.
  • 7.2 out of 10 confidence ratings from subject matter expert and users of Reddit for support
  • We tested our strategy on 25000 users from Coronavirus and covid19_support community pairs on Reddit who express anxiety and depression with certainty.

• Knowledge Infused Policy Gradients with Upper Confidence Bound for Relational Bandits
  • Knowledge Infusion in the Relational Bandits learning setting.
  • Deriving a Upper Confidence Bound style strategy for effective explore-exploit trade-off.
