Time-shifting Method to Mitigate Discussion Stagnation and Promote SNS Collaboration

抄録

This research proposes a function of SNS to reduce “stagnation of discussion, ” which hinders collaboration on SNS, as in the case of knowledge-building communities. Although knowledge-building may presuppose a kind of reciprocity where members perform their collective cognitive responsibilities, there are times when discussions cease and reciprocity appears to no longer be expected by participants, which may undermine their motivation to continue the collaboration. We have examined a method for delaying the appearance of posts on SNS by classifying them according to their time-sensitivity and the degree of author's contribution to the community. Such posts are displayed immediately after they are written, while ones with low time-sensitivity and posted by frequently contributing members are stocked for a while and displayed when the posting frequency decreases. This method can give the impression that the activity of the members was continuous, without stagnation of the discussion.
