Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an examination question processing device using online handwritten character recognition technology.

[Prior art]

Traditionally, entrance exams and employment exams were scored by hand by manually grading each examinee's answer sheets for each subject, and then inputting the resulting scores, along with the examinee number, into a computer for processing. In this method, once the scoring results have been input into the computer, any subsequent processing can be done using a program built into the computer, but the drawback is that the scoring and input of the results into the computer must be done manually. Ta.

Next, another method is to grade using an optical mark sheet league, but since the mark sheet league is used, it is necessary for the examinee to write the answers with marks, so there are so-called true/false questions or In addition to multiple-choice questions in which the correct answer is chosen from multiple answer candidates, we emphasize the necessity of essay-type questions in order to develop a diverse personality and to know one's true abilities. The major drawback was that the questions were difficult to answer. In addition, an even bigger drawback is that when the scorer is simply a key buncher, the scoring results are entered into a calculator, so it is no exaggeration to say that errors related to key bunching are bound to occur. This trend is increasing, and in addition to the fact that the scorers themselves make mistakes when tallying up the scores for each question, the current situation is that it is becoming a hidden social problem.

[Purpose of the invention]

The purpose of the present invention is to eliminate these drawbacks by using online handwriting recognition technology to input the written data into a computer online when a grader scores essay questions and writes the results on the answer sheet. This is an attempt to eliminate errors in key bunching as well as eliminate errors in the scorer's own scoring of scores for each question, and will be explained in detail below.

[Structure of the Invention] FIG. 1 is a block diagram showing one embodiment of the present invention.
2 is a tablet, 2 is a recognition unit that recognizes online handwritten characters, 3 is a central processing unit (hereinafter referred to as CPU) including memory, 4 is a cold cathode tube display (hereinafter referred to as CRT), 5
is a printer (hereinafter referred to as PR), 6 is a floppy disk drive (hereinafter referred to as FDD), and 7 is a keyboard (hereinafter referred to as K).
It's called B. ). Figure 2 shows a half-frame virtualized by the recognition unit 2 on the tablet 1. In Figure 2, the horizontal direction is X, the vertical direction is Y, and the half-frame for 22 characters, for a total of 440 characters, is drawn by the recognition unit 2. virtual on the tablet 1.

To explain the tablet 1 and the recognition unit 2, the tablet 1 places a sheet of paper on it, and when a character is written on the paper, the stroke is recognized as an xy coordinate string by the recognition unit 1.
will be sent to. Unlike the character frame, the xy coordinate string indicating a stroke is sent to the recognition unit 2 every moment with a resolution of 10 lines/1 cn in both the X and Y directions. Recognizes a collection of points as a stroke and recognizes characters as a collection of strokes. Tablet 1
Since the strokes sent from the above are normalized and recognized by the recognition unit 2, the size of the characters written on the tablet 1 can be arbitrary, and it is written in a half frame, and the character frame is this character "0". "Half frame X14." where the center part 9 is located.
Y5 is sent to CPU 3. Therefore, from recognition unit 2, CP
The recognized character '0'', X character frame '°14'', and Y character frame '5'' will be sent to U3.The recognition method is not the purpose of this invention, so detailed explanation will be omitted. Omitted.

Figure 3 is a diagram showing an example of an answer sheet, and shows numbers 1 from ■ to O.
0 indicates the question, and * mark 11 indicates the name, examinee number, answer, etc. that are already written on the answer sheet when it is delivered to the grader. The number 12 in the upper right corner of the answer column indicates the points allocated for each question. It is not necessary to record the score allocation on the answer sheet, but it is included for convenience of explanation.

Now, in the case of this device, the characters to be recognized are ○, ×, 1 from 0 to 9.
Two types of characters are sufficient. For practical purposes, it is easy to recognize 12 types of characters at the current state of the art, although some types of modified characters are allowed for each type.

(5) Next, preparations for using the embodiment of the present invention shown in FIG. 1 as a scoring machine will be explained.

As explained above, since the virtual character frame on the tablet 1 shown in FIG. 2 and the answer column on the answer sheet shown in FIG. 3 do not match, preparations are made to match them. Figure 4 is a diagram showing the relationship between the virtual half-frames on the tablet and the answer sheet, and is a superimposition of Figures 2 and 3. The answer to question ■ is written in the right column of ■. If you write ○× in the answer column to indicate whether it is correct or incorrect, you will get (xa, yi), (xs, yl).

The recognition unit 2 selects any half-frame number within the range of (X3, Y2), (X8, Y2) with the recognition result of 0 or ×.
It will be sent to PU 3. Therefore, as a preparation, the time period ■...X3-8. YI X3-8. Space within character frame of Y2...X11~141YI X1

~14. As shown in Y22, a table of correspondence between the virtual half-frames on the tablet and each column of answers on the answer sheet is stored in the memory of the CPU 3.

In the grading stage, the answer sheet is placed on the tablet 1, and when the grader writes ○ or × depending on the contents of the answer column, the recognition unit 2
It is recognized by the CPU 3 and sent to the CPU 3 along with the half frame number.

The CPU 3 makes a correspondence between the half-frame number and the question number, identifies which question the result is, and adds up the points allocated separately to the CPU 9. For example, as shown in Figure 4, if you write a circle in question ◯, the recognition unit 2 sends the information 0, 5, 2 to the CPU 3, which means that the X coordinate is 5 and the Y coordinate is 2. This is considered to be the evaluation of question ■, and since the result is ○, a score of 5 is given. In FIG. 3, each question has one answer column, but each question may be divided into a plurality of questions. For example, if question ■ is divided into 5 questions and each question is worth 1 point, 3 questions are ○.
If the second question is x, the score will be 3 points, but in this case, the CPU 9 can recognize that the score for question (2) is 3 points using the method described above. Here, you can either display the results of the question (■) on the CRT 4, have the grader look at the displayed score, and enter it as is in the score column for the question (2), or
4 in the score column without any child, the recognition unit 2 recognizes the result and sends it to the CPU 3, which corresponds to the question number obtained from the ○, ×, and half-frame number written in the answer column. The score is compared with the score given by the scorer obtained from the numbers and half-frame numbers, and if there is a discrepancy, a warning is given to the scorer.

After completing the sequential scoring as described above, the examinee number will be
゛The scorer enters the numbers entered by the examinee into the KH2, or by tracing the numbers from above, the recognition section 2 recognizes them and inputs them into the CPU. Next, the total score is calculated using the same method as the score for each question (any method described above is fine).
The scorer will decide while checking with U3 and CRT4. As a result of the above scoring by the scorer using the method of the present invention, the examinee number, score for each question, and total score are recorded on the FDD 6, and at the same time on the P.
Printed on R5.

〔Example〕

As explained in detail above, in the above embodiment, the scorer calculates the score at the same time as the scorer scores, and the result is FDD 6
Since the results are recorded on the PR5 and printed on the PR5, there is no need for the grader to rekey the grading results. It is possible to eliminate all errors when printing. Also, as explained above, the score for each question given by the grader and the total score are stored on the CPU.
Since it is possible to check the progress of the grader's scoring inputted in step 3, it is possible to prevent errors when the grader tallies the scores for each question. This method allows the scorer to record the scores shown on the CRT J directly in the score column without adding up the scores for each question or the total score. It is also useful for preventing transcription errors. If there is an error in transcription from CRT 4 to the answer sheet, the score will be entered correctly, but the examinee will be notified of the incorrect score, and the relationship of trust between the examinee who is taking the test (9) and the examinee will be maintained. However, according to the embodiment, not only counting errors but also transcription errors as described above can be prevented. In addition, since the recognition unit that virtualizes the character frame for the tablet is commonly used as an input panel for handwritten character input devices, it can be used as is, easy to implement, and useful for cost reduction.

In the above embodiment, it has been explained that ○ or × is entered in the answer column of the question, but instead of simply ○ or ×, the scorer may enter any score that he or she deems appropriate. In other words, as shown in Figure 3, the problem ■
, Question 0 has a score of 20 points, but this is an essay type question, and depending on the content of the answer, it may be necessary to score anywhere between 0 points and 20 points, so it may simply be 0 points or 20 points. In many cases, it cannot be simply evaluated.

In such a case, if you write a number instead of ○ or × in the answer column, it can be recognized as the score for that question. This is possible in the same way as already described,
This is possible by determining the question number from the numbered half box and treating it as a number with the score (10) written for that question on the CPU 3. This scoring system can also be used flexibly for essay-type questions. method can be provided.

Furthermore, as another application method, a communication control unit such as a modem may be provided in place of the FDD 6 and connected to the center computer system through a communication line.

〔Effect of the invention〕

As described in detail above, the present invention eliminates the need for manual grading of scoring results, prevents aggregation errors and transcription errors caused by the grader's own carelessness, and improves the accuracy of essay-type questions. It is possible to provide an innovative answer processing device.
