英文摘要：

This study collects, processes and analyzes a large amount of data from the community forum named ＂MOOC College＂ to acquire the evaluation indexes for MOOC. Combined with the existing online course evaluation system, a MOOC evaluation model is established by using the fuzzy comprehensive evaluation method based on Vague set. The MOOC evaluation model, which is more objective and truthfulness, may help MOOC learners to evaluate the quality of MOOC, thereby providing references for the platforms, administrators and developers to improve the quality of MOOC.
