Abstract
While the number of MOOCs users in China has been increasing dramatically, the users still face the risk to give up learning in the half way due to unfamiliarity with the course structure, prerequisite courses and so on. To resolve this problem, the MKD plays an important role by providing a clear structure map of the course, helping user to realize about the appropriate learning path as well as the knowledge relationship. In this article, a method of constructing a usable MKD in Chinese has been raised based on online courses. The online course data are obtained by web crawling from the MOOCs sites, then processed through the data clean and data fusion after which the MKD is extracted and evaluated. This method is applied to all the existing MOOCs courses thus has showed practical significance.
