Abstract

In this paper, we model knowledge activities, in which people continuously createideas about some themes and theorize or materialize them into knowledge, as a cycleof four phases with discussions about ideas and knowledge and propose a system tosupport knowledge activities. First we generate minutes linked with video and audiodata of discussions and metadata as hints on instrumental discussions. Then, users can arrange the minutes to contemplateruminate the discussion contents in the systemfor the purpose of that utilizeation the discussion contents oforn ordinary taskssuch as examination, implementation, and verification. Therefore, users convert theideas created through ordinary tasks into presentation material for subsequentnextdiscussions. We believeconsider that it is possible to activate knowledge activitiestoby support to run over this cycle.
