Abstract

The invention discloses a template matching-based programming job correction method, a device, a system and a medium. The method comprises the steps of obtaining a to-be-corrected programming job; matching the to-be-corrected programming homework with a preset correct answer template set, and judging whether a correct answer template matched with the to-be-corrected programming homework exists or not; if yes, marking the to-be-corrected programming homework as a correct answer and classifying the to-be-corrected programming homework into a correct answer template set; otherwise, classifying into a to-be-processed job set; and performing clustering processing on the to-be-processed job set, extracting a new correct answer template, classifying the new correct answer template into a correct answer template set, and continuing performing job matching until all correct answers are matched. According to the embodiment of the invention, the correct answer template set is updated through matching and clustering, the category of the correct answer template is gradually improved, and manual correction is replaced by automatic matching of the programming homework and the correct answer template, so that not only is intelligent correction realized, but also the coverage rate and efficiency of automatic correction of the programming homework are improved.

Description

technical field [0001] The invention relates to the technical field of graphical programming, in particular to a method, device, system and medium for correcting programming operations based on template matching. Background technique [0002] In the current online children's programming courses, students' after-school programming homework correction mainly depends on manual correction, mainly because the graphical programming homework is composed of graphical building block code blocks representing various variables and operations. The degree of freedom is high, and a job usually corresponds to multiple implementation methods. The existing automatic correction only provides a few correct answers, resulting in a low coverage rate of correct answers for automatic correction, which cannot meet the automatic correction needs of diverse programming tasks. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of t...
