Abstract: Question-intent understanding and recognition is an important part of question-answer and dialogue systems, which includes contextual semantic understanding and intention classification subtasks. Although a large number of research results have been achieved in the task of question intention determination, there is still a lack of systematic review and summary of related research work. Therefore, this paper compares the recent research, starts from the concept of question intent understanding and determination, introduces its research purpose and significance, summarizes the evaluation methods and data sources, portrays the generational differences between methods, and focuses on the application of currently popular deep learning methods to question intent understanding and determination, and finally explores its potential development direction in the future.
