基于操作序列的自动测评关键技术及其应用研究

摘要

基于操作序列的测评方式虽然复杂,但能够全面、客观地反映考生实践操作技能.文章首先解决了操作序列通用框架的表示问题,在此基础上,建立基于专家系统的操作测评模型和实操考核自动评分流程,最后给出自动测评关键技术在航海仪器测评系统中的实际应用,实现了对学生评分结果的相对客观、公正,大大提高了实操考核的工作效率.%The assessment mode is complex based on the operation sequence, but it can reflect the practical operation skills of examinee comprehensively and objectively. The paper firstly solves the framework's general representation of operation sequence. Then on these bases, the paper establishes operation evaluation model based on expert system and automatic rating process of operational examination. Lastly, the practical application of the key technologies in the evaluation system of navigation instruments is provided, realizing the relatively objective and fair grading result, greatly improving the efficiency of operational examination.
