This manuscript reports the results and findings obtained by the operation of the dialogue system "V-TA" that
is used in a practical training class in Kindai University "Media Informatics Project II". Our 4 month operation
revealed the following implications: (i) Cooperation between Students, TAs, and Lecturers accelerates efficient
collection of dialogue corpus; (ii) V-TA plays a role as a feedback collection mechanism from students for a class;
and (iii) V-TA halves the cost of QA tasks since it can correctly answer questions from students with 56% probability.
