The application relates to the technical field of
test question duplication checking, and specifically discloses a
test question precision duplication checking method and
system, which comprises the following steps: constructing a
test question database, collecting and storing test question title information and answer information;
processing the test question information, obtaining a duplication checking test question, preprocessing the duplication checking test question, and then extracting the text information by
sentence decomposition with
punctuation marks as intervals; performing traversal duplication checking comparison between the duplication checking test question and the test question
database title, obtaining a repeated
signal; marking and displaying the repeated
signal in the
database title in the database obtained through the traversal duplication checking, comparing the number of words of the duplication checking test question with the number of words of the database title, preliminarily judging the
coincidence degree of the test question, and when the keyword
coincidence degree is high, it is indicated that the meanings of the duplication checking test question and the target test question are similar; and based on the total value difference of the test
question text sentences of the duplication checking test question and the similar text
sentence meaning, the duplication checking test question and the target test question are calculated and judged to be repeated or not.
