This paper describes a CSCL (Computer Supported Collaborative Learning) Assessment tool that aims at visualizing discussions among learners participating on electronic forums using a text-mining technique. The software, named “i-Bee” (Bulletin board EnvisionEr), is able to visually show the co-occurrence relations of topic keywords of each learner using correspondence Analysis. Furthermore, i-Bee can show how actively each learner discusses; how each learner contributes to online discussions; and the frequency the learners use each keyword. In this paper, the authors report the rationale, the basic algorithm, and the implementation of i-Bee.
