Description: |
Sheizaf Rafaeli is director of the Center for the Study of the Information Society and a professor in the Graduate School of Business Administration at the University of Haifa in Israel. In this talk, he will discuss how question and answer sites, such as Yahoo! Answers, are places where
users ask questions and others answer them. He has investigated predictors of answer quality through a comparative, controlled field study of responses provided across several online Q&A sites. Along with several quantitative results concerning the effects of factors such as question
topic and rhetorical strategy, he will present two high-level messages. First, you get what you pay for in Q&A sites. Answer quality was typically higher in Google Answers (a fee-based site) than in the free sites he studied, and paying more money for an answer led to better outcomes. Second, he found that a Q&A site's community of users contributes to its success. Yahoo! Answers, a Q&A site where anybody can answer questions, outperformed sites that depend on specific individuals to answer questions, such as library reference services. All are welcome to attend. To promote in-depth intellectual engagement during the seminar, everyone is encouraged to read Rafaeli's paper in advance.
