Abstract
Community Question Answering (CQA) has recently become a popular means of satisfying personal information needs. However, as the quality of answers posted on CQA sites varies widely, there is a need to effectively extract high-quality answers from CQA. In this study, we manually analyzed the high-quality answers from Yahoo! Chiebukuro data by multiple assessors and identi?ed criteria used by assessors to evaluate high-quality answers.
