Beyond Exchangeability: The Chinese Voting Process
This addresses the issue of biased voting in online platforms for users and moderators, but it is incremental as it builds on existing models of social processes.
The authors tackled the problem of modeling helpfulness votes in online communities as a social process influenced by biases, proposing the Chinese Voting Process (CVP) and evaluating it on Amazon reviews and StackExchange forums to measure response quality and community behavior.
Many online communities present user-contributed responses such as reviews of products and answers to questions. User-provided helpfulness votes can highlight the most useful responses, but voting is a social process that can gain momentum based on the popularity of responses and the polarity of existing votes. We propose the Chinese Voting Process (CVP) which models the evolution of helpfulness votes as a self-reinforcing process dependent on position and presentation biases. We evaluate this model on Amazon product reviews and more than 80 StackExchange forums, measuring the intrinsic quality of individual responses and behavioral coefficients of different communities.
