Expertise Measurement
Expertise is measured via a score assigned to each individual based on their past Github activity relating to the OP Stack. The GitHub accounts of guest voters are collected in the application flow to become a guest voter. Badgeholders are invited to add their GitHub account to their Optimist Profile in the process of completing Season 6 onboarding. The scores are assigned using an algorithm developed through a collaboration between Karma3Labs 5 and Open Source Observer, and is based on Hubs and Authorities. The algorithm is more complex than EigenTrust, because it incorporates two entities: GitHub Repos and GitHub Users, both of which can have ‘trust’ and give ‘trust’ to each other. The algorithm used to rank expertise will be open sourced after the conclusion of Round 5 to avoid influencing the experiment. You can find more details on guest voter selection here 11
