Abstract Aiming at the problems of students' poor grasp of organizational structure, insufficient understanding of knowledge difficulty, unplanned learning and weak learning purpose in the course of Object-oriented Programming(Java).The research on the construction of Java knowledge map is proposed in this paper under the background of big data. Under the background of big data, a result-oriented Java knowledge map for teachers and students is constructed from three links of knowledge points acquisition and thermal analysis by using web crawler, knowledge point association mining by using Numpy database and knowledge map visualization.The map contains not only the relationship between knowledge points, but also the difficulty of knowledge points and students'mastery of knowledge points. It can be used not only as a navigation of learning knowledge, but also as a means of process evaluation. Through practical application, it is very useful for the design of difficult content and for the mastery of students'knowledge structure, and the breakthrough of key and difficult points in teachers' teaching. It tries to provide reference for the construction of knowledge map of other programming courses.

Key words： big data knowledge map knowledge navigation process evaluation
