Xiaofei Li · Journal of Physics Conference Series · 2021
Abstract A semantic navigation method based on ontology was proposed to solve the problem of digital library information trek. In this paper, the domain concept was extracted based on the knowledge base, linguistics, combined word length ratio, domain correlation and domain consistency.Finally, the domain ontology visualization scheme was put forward, and the related updating technology, wide-angle and aggregation technology were analyzed.The process of using Touch Graph to realize the navigation of ontology visual information was also analyzed.
