カンファレンス (国際) Who stays longer community QA Media? - User Behavior Analysis in cQA -
The 7th International Conference on Social Informatics (SocInfo 2015)
Macro and micro analyses of why and when users stop asking and/or answering questions on a community question answering (cQA) site were done for a ten years' worth of questions and answers posted on Yahoo! Chiebukuro (Japanese Yahoo! Answers), the biggest cQA site in Japan. The macro analysis focused on how long participants were active in the QA community from the viewpoints of several user characteristics. In turn, the micro analysis focused on how the participants ’behaviors changes. The behaviors of both askers and answerers were found to change over the time of their active participation: the askers tended to expand the range of categories for which they asked questions while the answerers tended to contract the range of categories for which they answered questions.
