The traditional auxiliary teaching question-answering Artificial Intelligence(AI)assistant has a large number of answering errors.Therefore,a auxiliary teaching question-answering Al assistant based on knowledge graph is designed.Firstly,a question and answer database based on teaching knowledge is constructed.Then,according to the question-answering database,the question-answering selection algorithm based on knowledge graph is designed.Finally,the teaching question retrieval service is carried out.The experimental results show that the designed auxiliary teaching question-answering AI assistant based on knowledge graph has a relatively low number of answer errors,accounting for 1％of the entire dataset.This indicates that the accuracy and reliability of the designed AI assistant in assisted teaching question-answering are high,and it has practical application value.
