Abstract:
Online communities of questions and answers became important places for users to get information and share knowledge. We investigated metrics and strategies that allow the identification of users that are willing to help and provide good answers in a community, which we call the reliable people. In order to provide better performance on finding these users, we also raised some strategies for scope reduction. Then, we applied these metrics and strategies to three online communities of questions and answers available on the Web, which also provide user reputation grades, so it would be possible to verify the results on finding the reliable people.
