The design and implementation for automatic evaluation system of virtual experiment report

This paper designs and implements an automatic evaluation system for experimental reports in the field of university computer virtual experiment. The evaluation type is divided into three types: the only answer type, the rule-related type and the subjective short answer type. For the problems of the subjective short answer, a simple and effective method based on the participle of the standard answer and the multi-level semantic similarity is proposed in this system. The application of this system in the university computer virtual experiment platform shows that it not only facilitates the mastery of the experimental knowledge points, but also ensures the accuracy rate and greatly improves the efficiency of judging.
