Description

Test paper scoring method

The present invention is a method for automatically evaluating and modifying test papers, especially a method that can be used for handwritten answers.

Examination is currently a method of evaluating learning results, and it is also an objective method used to judge whether examinees meet relevant qualifications. However, the homework burden of changing test papers is relatively huge. Often a reviewer needs to consult dozens to hundreds of answers in a short period of time. When he is tired, he is prone to errors. Correcting homework requires a lot of time and manpower to complete.

Beginning about 20 years ago, there is an automatic scoring system in which the answerer marks the answers to multiple choice questions or yes/no questions with colored pens at the corresponding position on the designated answer card. However, this answering method requires the answer The student goes back and forth between the test paper and the answer card several times. If there is a wrong place in the middle, it will cause all the answers in the back to be misplaced, so this method is not conducive to the answering of the question.

In order to overcome the above-mentioned problems, the present invention provides an examination paper grading method, which overcomes Overcome the above shortcomings that are limited to multiple choice questions and yes or no questions, and candidates can write directly on the examination paper without using additional answer cards. This method can also check the areas that the system cannot pass through and correct the correct answer according to the situation. , After the division, it is directly provided to other reviewers for approval, which increases the efficiency of correction.

The test paper scoring method of the present invention includes: a test paper image recognition step, a batch remarking step, a scoring step, a dispatching step, and a total score calculation step.

Wherein, the image recognition step of the test paper: image recognition is performed on at least one test paper image to obtain at least one answer data on the test paper image. Marking and marking steps: Compare the answer data with one of the pre-stored standard answers, and mark a correct symbol or an incorrect symbol or a correct answer in the position of each answer data on the examination paper image. Grading step: According to the result of comparing the answer data with the standard answer, calculate the score. If the response data includes a sentence response area, then a dispatch step: send each sentence response area to at least one reviewer for scoring and scoring. Total score calculation step: After returning the scoring result of the sentence as the answering area, add the score obtained in the scoring step to obtain a total score, and the total score can be marked on the examination paper image.

Through the above method, the answerer can directly answer the question on the test paper without filling in other answer cards. It can also be used to fill in the question to change the question. Moreover, it can directly send personnel to correct the sentence to avoid personal personal communication. Give unfair results. In addition, the results of the correction will also be displayed on the test paper file, so that the respondent can grasp the problem in the future. The present invention not only overcomes the conventional problems, but also improves the speed and accuracy of paper revision, and has the effect of deriving application data.

For those who have advanced, this method further includes an answer establishment step, which will have the correct answer After the examination paper is subjected to image recognition, the answer on the examination paper is obtained and set as the standard answer. With this step, the tester can also write the answer directly on the test paper, and hand it over to the system for direct identification and storage, which improves the convenience of making answers. In addition, the questions and answers can be stored synchronously to form the content of the question bank.

Those who enter, can perform a typos correction step before the dispatch step, and identify the typos in the sentence in the answer area and mark it in the sentence answer area. After the system performs text recognition and semantic analysis, it can determine the typos in each sentence, so as to reduce the burden of the sentence reviser.

Furthermore, it may further include a question bank creation step, which is carried out together with the answer creation step to identify and store the questions, thereby forming a question bank. In this way, these questions can be used to set up the test paper.

It can be seen from the above that the present invention can automatically correct test papers. Whether it is a handwritten answer or a printed answer test paper, it can be automatically graded after being processed by this method, which overcomes the problem of requiring a lot of manpower to complete the correction work and answer the questions The readers can directly receive the corrected electronic files, which is more convenient than the previous paper copies. At the same time, the standard answer can also be directly written by hand, which greatly improves the convenience of the questioner.

Fig. 1 is a flowchart of an embodiment of the present invention.

Fig. 2 is a flowchart of a method for establishing a question bank based on an embodiment of the present invention.

Please refer to the flowchart of the embodiment shown in FIG. 1. The steps of a method for grading test papers in this embodiment are performed by a computer system or others, including: a test paper image recognition step S1, a batch remarking step S2, a scoring Step S3, a dispatch step S4 and a total score calculation step S5.

Wherein, the test paper image recognition step S1: Perform image recognition on at least one test paper image to obtain at least one answering data on the test paper image. The answer data can be text, graphics, numbers, and sentences. When the image is recognized, the position of the answer can be distinguished according to auxiliary symbols such as area, font, color, brackets, and then the content is recognized to obtain the answer written on the answer sheet. It can be applied to various types of hand-written questions, such as multiple-choice questions, true-false questions or fill-in-the-blank questions.

Marking and marking step S2: Compare the answer data with one of the pre-stored standard answers, and mark a correct symbol, an incorrect symbol, or a correct answer on the test paper image corresponding to the position of each answer data. After the content is identified and obtained through the above step, correct it through this step, that is, compare it with the correct answer, and during or after the correction, you can mark the right or wrong symbol on the image of the examination paper, or The correct answer is directly imprinted on the above, so that the respondent can know the correct answer after receiving the corrected test paper.

Scoring step S3: According to the comparison result of the answer data and the standard answer, the score is calculated. The score can be calculated automatically according to the result, reducing the occurrence of score calculation errors.

Then, if the answering data includes a sentence answering area, a dispatch step S4 is performed: each sentence answering area is sent to at least one reviewer for scoring and scoring. When trying When the answer part of the test paper will be described in text, you can use this step to send the sentence answering area to the reviewer, and the reviewer will carry out the corresponding correction operation. Because the respondent of the test paper can be hidden during the transmission, so There will be no chance for the reviewer to give unfair results due to the personal relationship of the respondent or any other factors. At the same time, through the sending of the system, the case can be dispatched fairly and efficiently, and the content of the grades given by each reformer can also be recorded, which will be used as a basis for adjusting the proportion of scores according to different reformers in the future when correcting the results manually. Improve fairness.

Total score calculation step S5: After returning the scoring result of the sentence as the answering area, add the score obtained in the scoring step to obtain a total score, and the total score can be marked on the examination paper image. After the total score calculation is completed, it can be sent to the answerers.

The test paper grading method of this embodiment described above is capable of allowing answerers to answer in the most common way, and the grading results can be directly transmitted or downloaded by answerers. Through the electronic setting, the layer display setting method can also be added, that is, the marking annotations or symbols of the score are set up on a layer or multiple layers, and stacked on the original drawing file layer by layer, so that the respondent can choose to have no annotations ( That is, the layer with marked comments is not displayed), and the original answer is displayed, which is helpful for review and confirmation. This method eliminates the need for answerers to change their old answering habits, overcomes the problems of acquaintance, and at the same time shares the workload of the correctors to avoid the occurrence of ills.

Please refer to FIG. 2, the method of this embodiment further includes an answer creation step S8. After image recognition is performed on the test paper with the correct answer, the answer on the test paper is obtained and set as the standard answer. After this step, when the correct answer is established, it can also be done by handwriting the answer, which can improve the convenience of establishment.

Please cooperate as shown in Figure 2 and proceed further before the dispatching step S4: a typo modification step S6, the sentence is identified in the sentence in the answer area and marked in the sentence Sentence in the answer area. This step can save the time of the follow-up reviewer, and there are objective data for the reviewer as one of the basis for scoring. In addition, the identification of typos can be combined with algorithms such as semantic analysis to identify typos and improve the recognition ability. For those who enter, the typos recognized by the system can allow subsequent reviewers to oppose options. For example, set an "x" symbol in the correction section. When the reviewer presses the "x", the word marked by the system will be deleted. In this way, the correct text can be maintained after being read by the reviewer. Furthermore, artificial intelligence (AI) related technologies can be combined to generate algorithms, so that the revision of sentences is closer to actual words, rather than confined to words in databases such as dictionaries. In addition, deep learning or algorithm establishment can be carried out according to the scores given by each reviewer for different content, and the ability to automatically give sentence scores is derived.

Further, it can be combined with a question bank establishment step S7, which is carried out together with the answer establishment step to identify and store questions, and then form a question bank. This question bank can be used by test paper producers as random questions, and answerers can also practice.

Based on the above method, the present invention further provides an examination paper scoring system, which includes an image capturing device and a computing device. The image capture device is used to capture the image of the test paper after answering the question, and it can be an image capture device on a mobile device, a camera, a video camera or a scanner. The computing device signal is connected to the image capturing device, and after receiving the image, it is used to execute the aforementioned method steps. When the calculation is completed, the result can be sent to the specified location in a specified way. For example, the computing device has network connection capability, and it can upload or send it through the network, or use peer-to-peer file sharing technology. Transmit. In the dispatch step S4, information can also be transmitted through the network, and corresponding distribution operations can be performed in accordance with the system settings.

In addition, the embodiment of the present invention also includes an examination paper grading software, which can perform an image capturing step and the aforementioned examination paper grading method after being installed in a computing device. Image capture The step is to control an image capturing device connected to the computing device to capture images of at least one test paper; and the scoring method as described above. In addition, if the image of the test paper is captured through the image capture device on the mobile device, various image corrections can be made through algorithms to make subsequent identification easier. In addition, the device on which the software is stored is also one of the protection scopes requested by the present invention, and it can signal connection with the installed device through installation files, executable files, or decompression.
