Are Good Questions Scarce in Domain Specific Q&A?
○Andrew Vargo,Shigeo Matsubara(Kyoto University)
This paper explores domain specific Question and Answer (Q&A) and the issue
of information scarcity. Many Q&A forums use a point-based reputation
system as a method to signal expert users and to gamify the experience for
users. This has been used in Q&A networks such as Stack Exchange, which we
look at in this paper. As time progresses, we find that the rate of
reputation-valuable Q&A exchanges decreases, thus challenging the efficacy
of the reputation system. In addition, we observe a shift in domain
specific systems where answers start out as the scarce resource, but are
eventually replaced by questions.
