Abstract

Yahoo! Answers is the largest Q&A service with hundreds of thousands of questions asked and answered every day.  Traditional moderation systems failed to scale with the products growth. To address these challenges the team deployed a Community Moderation system which empowering trusted Answers members to report and remove abusive content automatically. One of the challenges to making the system work was to understand who to trust. The Answers team built a rich reputation model based on an analysis of over a dozen different system actions. Creating a successful community moderation system required changes in technology, community guidelines & policy, and user experience design.
