Problems solved by technology

However, for calculation and analysis problems that contain calculation expressions, deep learning models are not the only choice. Currently, deep learning models cannot verify the correctness of complex calculation expressions.
Calculation and analysis questions cannot be judged solely by the calculation results. For example, the calculation expression in the candidate's answer is correct, but the test taker did not give the calculation result. According to the scoring rules, such cases may get some points. The unit of the calculation result is inconsistent with the unit of the calculation result in the reference answer. At this time, a unit conversion is required. This type of unit conversion requires prior knowledge

Embodiment Construction

[0048] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0049] Such as figure 1 An intelligent marking method for calculation and analysis non-choice questions is shown, including the following steps:

[0050] S1: Perform text processing on the reference answer text and the examinee answer text.

[0051] For each character in the reference answer text and the examinee’s answer text, convert rounded characters into half-width characters, convert Chinese symbols in mathematical expressions into English symbols, and convert percent values ​​into decimal values.

[0052] S2: Extract structured information from the reference answer text and set scoring rules to form an answer template.

[0053] First of all, it needs to be explained that the calculation steps of the calculation and analysis non-choice questions in this embodiment adopt the form of structured information, and the form of structured information is ...

Abstract

The invention provides an intelligent test paper marking method for computational analysis type non-selective questions. The method comprises the steps: carrying out text preprocessing on a referenceanswer text and an examinee answer text; performing structured information extraction on the reference answer text and setting a score rule to form an answer template; performing structured information extraction on the examinee answers to form alternative answers; and scoring the alternative answers based on the answer template, and summarizing scores of the alternative answers according to the calculation steps to form scoring data. According to the invention, automatic paper marking of computational analysis questions can be achieved, manual paper marking deviation is eliminated, and the paper marking efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of examination evaluation, and more specifically relates to an intelligent marking method for calculation and analysis non-choice questions. Background technique [0002] In recent years, with the development of natural language processing, computer-aided intelligent marking technology based on deep learning has become a research hotspot in the field of examination evaluation. However, for calculation and analysis topics that contain calculation expressions, deep learning models are not the only choice. Currently, deep learning models cannot verify the correctness of complex calculation expressions. Calculation and analysis questions cannot be judged solely by the calculation results. For example, the calculation expression in the candidate's answer is correct, but the test taker did not give the calculation result. According to the scoring rules, such cases may get some points. The unit of the calculation ...
