This paper summarizes the technical routes of the four most representative evaluation metrics of the automatic grammatical error correction systems. Firstly, it introduces the characteristics and composition of each metric, then summarizes its defects, and finally puts forward some suggestions for the future development of the metrics. This paper holds that the application of natural language processing technology should be strengthened in the future development of evaluation metrics.
