Automatic correction method and device for online test questions and storage medium

Abstract

The invention discloses an automatic correction method for connected test questions. The method comprises the following steps: acquiring test question images of the connected test questions; identifying an answering connection line in the test question image, and determining a first image block and a second image block corresponding to two end points of the answering connection line; respectively identifying first test question information in the first image block and second test question information in the second image block; judging the type of a connected test question according to the first test question information and the second test question information, and judging whether the first test question information in the first image block is matched with the second test question information in the second image block or not by adopting an algorithm and / or a model corresponding to the type of the test question; if the judgment result is yes, the connection is correct, and if the judgment result is no, the connection is wrong. According to the method, the test question information corresponding to the two ends of the connection line is found out, the types of the connection test questions are judged, corresponding algorithms or models are adopted according to different types, whether the test question information of the two ends of the connection line is matched or not is judged, and therefore automatic correction of the connection test questions is achieved.

Description

technical field [0001] The invention relates to the technical field of online education, in particular to an automatic correction method, device and storage medium for online test questions. Background technique [0002] School education is the main way of learning scientific and cultural knowledge.
