Evaluation Method and System for Mathematics Subjective Questions

Abstract

The invention discloses a method and system for marking the answers of mathematic subjective questions. The method includes: performing word dividing on to-be-marked answer information, performing structural analysis on the to-be-marked answer information according to the work dividing result to acquire the relation between the answer information of a to-be-marked answer. The method has the advantages that due to the fact that relation between answer steps can represents the answer logic of a respondent, the answer logic of a respondent can be compared with the answer logic of a reference answer to obtain a first marking feature, the to-be-marked answer information can be marked according to the first marking feature, the problems that standard answers need to be organized and expanded, the expression forms and answering ideas and steps the answers of the respondents are possibly varied, the expansion result cannot cover all the possible answers, and incorrect marking is caused in theprior art are avoided, and the marking accuracy of the answers of open questions is increased effectively.

Description

technical field [0001] The invention relates to the fields of natural language processing and deep learning, in particular to a method and system for evaluating subjective mathematics questions. Background technique [0002] In the traditional teaching process, teachers, as the main body of examinations and homework review, undertake a large amount of workload for a long time. The evaluation work contains a lot of repetitive information, especially in the evaluation scenario of mathematics answering questions, the students' answer results often correspond to fixed knowledge points, and the repetition is more obvious. At the same time, with the gradual penetration of Internet technology and products into the education field, the audience of online education continues to expand, which further increases the number of examinations and homework reviews. On the other hand, when dealing with large-scale review work, teachers are easily disturbed by subjective factors such as fatig...
