The invention provides a lightweight
digital human lesson preparation
system based on an
intelligent agent, and belongs to the field of intelligent teaching. Through collaborative operation of four core modules of
knowledge graph construction and reasoning, multi-
modal cognitive agent, lightweight
digital human generation and intelligent teaching plan assistance, the problems of low efficiency of
resource integration, teaching content homogenization, insufficient
digital human interaction experience and the like in traditional lesson preparation are solved. The
knowledge graph construction and reasoning module is used for constructing a structured
knowledge graph and realizing knowledge point
association mining and teaching logic reasoning; the multi-
modal cognitive agent module is used for generating personalized explanation content according with a teaching target by fusing multi-
modal courseware analysis, semantic understanding and lecture style dynamic
adaptation functions; the lightweight digital human generation module is combined with model
pruning and emotion modeling technologies to synchronously output natural voice and a high-
simulation digital human image; the intelligent teaching plan auxiliary module helps the teacher to intelligently generate a teaching plan and a teaching outline according to the courseware content based on the knowledge graph.
