Identifying and Harnessing Expertise in Online Forums
Our goal is overcome the technical and practical limitations of current online forums by automatically identifying expertise and using this information to help individuals share and find expertise more efficiently. Analyzing millions of posts from Yahoo! Answers, we infer participants' expertise from their post-reply behavior, calibrating for differences across online cultures. By different cultures we mean that for some topics supportive or witty answers may be more highly regarded than informative ones, and the algorithms needs to account for these and other differences. Previously we examined Sun's Java Forum and successfully developed automated social network based algorithms whose ability to rate expertise was close to that of human raters.
