| Abstract: | Online communities provide a social sphere for people to share
information and knowledge. While information sharing is becoming a
ubiquitous online phenomenon, how to ensure information quality or
induce quality content, however, remains a challenge due to the
anonymity of commentators. This paper introduces moderation into
reputation systems. We show that moderation directly impacts strategic
commentators incentive to generate useful information, and moderation is
generally desirable to improve information quality. Interestingly, we
find that when being moderated with different probabilities based on
their reputations, commentators may display a pattern of reputation
oscillation, in which they generate useful content to build up high
reputation and then exploit their reputation. As a result, the expected
performance from high-reputation commentators can be inferior to that
from low-reputation ones (reversed reputation). We then investigate the
optimal moderation resource allocation, and conclude that the seemingly
abnormal reversed reputation could arise as an optimal result. The paper
concludes with a discussion of the development of a scientific
moderation system with application to academic publishing. |
