Online learning has become the most important mode of lifelong learning and one of the important directions of education transformation. Online learning needs the support of digital resources. The digital learning resource library is an important part of the new infrastructure of education in the digital era, which plays an important role in supporting online education, promoting the reform and transformation of education digitalization, and promoting the construction of the lifelong education system. The application of new technologies can promote the construction of digital resources and form an ecological chain of resource base construction and supply. Interdisciplinary knowledge association, presentation and intelligent push are constructed through open domain knowledge graph technology to form effective utilization of large resources and generate learning paths and resource association distribution map, which is of great significance to promote the application of big data in education and the development of intelligent education research.
