Answer correction method and device

An answer correction device, the device comprises:

• a memory, storing a program;
• a processor, executing the program to be configured to function as
• a determining module, configured to search in a question bank according to the test paper to be corrected, and determine a target test paper that matches the test paper to be corrected;
• a marking module, configured to mark an area of each answer on the test paper to be corrected as a first answer set, and mark an area of each answer on the target test paper as a second answer set;
• an adjusting module, configured to use a first preset algorithm to preliminarily match the each answer area in the first answer set with the each answer area in the second answer set, and adjust a position of the preliminarily matched answer area in the first answer set on the test paper to be corrected according to a position of the answer area in the second answer set on the target test paper;
• and
• a correction module, configured to determine a target answer area in the first answer set according to position information of the each answer area in the second answer set on the target test paper, and correct an answer in the determined target answer area according to the answer in the answer area in the second answer set, wherein an adjusted position of the target answer area on the test paper to be corrected is the closest to the position of the answer area in the second answer set on the target test paper,
• wherein the processor further executes the program to be configured to function as a matching module configured to determine the target answer area, and utilize a second preset algorithm to perform a bipartite graph minimum weight matching on the each adjusted answer area in the first answer set and the each answer area in the second answer set to obtain a final matching result between the answer area in the first answer set and the answer area in the second answer set.
