Construction of Adaptive Knowledge Graph with Learning Feedback—Taking the Operating System Course as an Example
In view of the problem that current subject Knowledge Graph lacks learners'learning behavior information,this paper takes the operating system course as an example,designs the operating system course ontology library with textbooks and Baidu Baike as the main data sources,and constructs the course Knowledge Graph according to the designed ontology structure.Meanwhile,the learning data generated by 142 students on the online open platform is taken as learning feedback to dynamically update the course Knowledge Graph.In this way,the Knowledge Graph can conduct dynamic learning path planning and provide learning resource recommendation according to students'mastery degree of knowledge points.It has corresponding reference value for constructing an adaptive discipline Knowledge Graph in a dynamic environment.
