You can test our prototype of RoboCHAIR
http://kt-robochair.ijs.si/ where you upload an article and get a list of questions that you can evaluate (are they understandable and/or relevant). It can be used also in a conference setting (where session chair can upload the questions and the conference audience can vote on the fly, and the best questions can be addressed to the author by a robot Nao.
Except for evaluating by voting, you can edit the questions, comment them or upload real questions you received or would formulate if you were reviewing an article or attending a conference. Any input would be of great help, since we need data in order to learn how to formulate better questions. Perhaps we could even try the setting with the robot on the next ICCC.
