Given that the foremost platform of online training, MOOCs give learners with rich training course resources, but program designers remain faced with the challenge of ways to accurately strengthen the standard of classes. Current exploration primarily concentrates on learners’ psychological opinions on distinct study course characteristics, neglecting non-psychological content material as well as the expenditures necessary to strengthen these attributes. This limitation causes it to be challenging for program designers to totally grasp the actual needs of learners and also to correctly Identify the key troubles while in the class. To beat the above difficulties, this study proposes an MOOC improvement strategy depending on text mining and multi-attribute conclusion-building.
