Our study

We performed a quantitative study on the usage of IRC meetings and studied the following 3 dimensions:

1.Discussion Volume (Are the meetings becoming more popular?)

2.Meeting Attendance (Are the meetings useful?)

3.Participants’ Contribution (Are participants active or just showing face?)
