On formal models for social verification
Chien-Ju Ho, Kuan-Ta Chen · 2009
The introduction of the ESP Game and other Games With A Purpose (GWAP) has demonstrated the potential of human computation in solving AI-hard problems. In such systems, users are normally required to input answers for questions proposed by the system, e.g., descriptions about a picture or a song. Since users may bring up irrelevant inputs intentionally or carelessly, and often the system does not have "correct" answers, we have to rely on the users to verify answers from others. We call this kind of mutual verification of users' answers "social verification."
