A fuzzy logic evaluating system to support Web-based collaboration using collaborative and metacognitive data

A fuzzy logic-based expert system, namely collaboration/reflection-fuzzy inference system (C/R-FIS,) is presented. By means of interconnected fuzzy inference systems (FIS), it automatically evaluates the collaborative activity, during asynchronous, written, Web-based collaboration. This information is used for the provision of enhanced support during the collaboration. The proposed model extents the evaluation system of a Web-based collaborative tool namely Lin2k, which served as a test-bed for the C/R-FIS experimental use. The results proved the potentiality of the proposed model to significantly contribute to the enhancement of the collaborative activity.
