Abstract

PROBLEM TO BE SOLVED: To enable proper correction and instruction by utilizing the input history of a learner by performing the correction and instruction by referring to the stored input history. SOLUTION: The input history when the learner generates answers is stored and the correction and instruction are carried out by referring to it. For example, the input history is used for an answer document analyzing process 105. An input history extracting process 104 extracts a history needed for the answer document analyzing process 105 from input histories received from an input process 103 and stores it in an input history storage means 102. The answer document analyzing process 105 divides it into character strings on the basis of sectioning symbols and properly connects them by referring to the input history storage means 102 to determine a document item of an answer document. A matching process 106 makes the determined document item of the answer corresponding to a correct answer document stored in a correct answer expression storage means 101, an inspecting process 107 compares pieces of information that respective document items have with each other to extract a difference as an error, and a correcting process 108 corrects it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0002]

2. Description of the Related Art As an educational support device for an essay problem, there is a method of associating a document item of an answer document with a document item of a correct answer document and extracting a difference as an error (for example, Japanese Patent Application Laid-Open No. Hei 7-181883). ).

FIGS. 37 and 38 show a conventional method.
This will be described with reference to FIG. FIG. 37 shows the configuration of a conventional education support device. The correct answer information storage means 3701 stores the correct answer expressions of the document items constituting the correct answer document. The input processing 3702 receives an input from a learner. The error extraction process 3703 divides the answer document of the learner into document items, compares the expression of the document item of the answer document with the expression of the document item of the correct document stored in the correct information storage unit 3701, and compares the difference. Is extracted as an error.
The correction process 3704 corrects the learner based on the error contents of the error extraction process 3703.

[0006] In addition, when the learner tackles the problem, the learner has to input from the beginning every time, regardless of the understanding state of the learner, so that there is a problem that the learning efficiency is poor. In addition, since the corrective instruction is performed based on the correct expression, the learner can learn only the expression for the correct answer, and cannot learn what expression is wrong.

[0007] In addition, there is a problem that the learner can learn only in the environment provided by the system, and cannot set the learning environment to the preference of the learner.

[0008] It is an object of the present invention to provide a method for performing more appropriate correction instruction by using a learner's input history.

Further, by extracting the same character string of the correct answer expression of the presented question and the correct answer expression of the question which has reached the correct answer in the past, and displaying the extracted character string in the answer area before answering the question, It is an object to provide a method for facilitating answer input.

In addition, by replacing a part of the same character string to be displayed with a similar expression and performing error correction learning,

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) A correction instruction method according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a correction instruction method according to the first embodiment of the present invention. In FIG. 1, a correct expression storage unit 101 stores a correct expression. The “correct answer expression” is described for each document item constituting the correct answer document, and is information for matching for matching with the document item of the answer document. Input history storage means 102
Stores the input history of the learner's answer input. Input processing 1
03 accepts a learner's answer input. The input history extraction processing 104 stores the input history of the learner in the input history storage unit 1.
02 is stored. The answer document analysis process 105 divides the learner's answer document into document items. The collation process 106 collates the document items of the answer document divided in the answer document analysis process 105 with the document items of the correct document stored in the correct expression storage unit 101, and associates them. Inspection processing 107 compares the information of the document item of the answer with the information of the document item of the correct document associated with the matching process 106, and extracts a difference as an error. The correction processing 108 performs correction with reference to the result of the inspection processing 107.

The configuration of an apparatus for realizing the correction instruction method according to the present embodiment will be described with reference to the drawings. FIG. 36 is a configuration diagram of hardware for realizing the present invention. In FIG. 36, a V-RAM 36 is used as a memory.
02 and a main storage device 3605 are provided. Input / output operations are performed by an input device 3603 such as a keyboard or a mouse. The external storage device 3606 includes the correct expression storage unit 101 and the input history storage unit 102 described above. Input from the learner is received through the network interface 3607, and the CPU 3604 performs an input history extraction process 104, an answer document analysis process 105, a collation process 106, an inspection process 107, and a correction process 108. The processing result is presented to the learner via the display 3601.

FIG. 2 is a flowchart showing the flow of the processing of this embodiment. FIG. 3 is a diagram showing an example of a question and an example of a correct answer document for the question. FIG. 4 is a diagram showing an example of an answer document for the question of FIG. FIG. 5 is a diagram showing an example of data stored in the input history storage means 102. FIG. 6 is a diagram in which the answer document of FIG. 4 is divided into character strings based on delimiters. FIG. 7 is a diagram in which the answer document of FIG. 4 is divided into document item units. FIG. 8 is a diagram showing data stored in the correct expression storage means 101. FIG. 9 shows the collation processing 10
FIG. 6 is a diagram showing a correspondence relationship between a correct answer expression and a document item of an answer in No. 6;

The processing flow of the first embodiment will be described with reference to FIGS. Here, it is assumed that the input history is used for the answer document analysis processing 105. In FIG. 1, an input process 103 receives an answer from a learner, and passes an input history of answers such as a keystroke content and a mouse event content to an input history extraction process 104. The input history extraction processing 104 extracts a history necessary for the answer document analysis processing 105 from the input history received from the input processing 103 and stores the history in the input history storage means 102 (step 201).

In the answer document analysis processing 105, the document is divided into character strings on the basis of the delimiters (step 202).

Further, the divided character strings are appropriately connected with reference to the input history storage means 102, and the document items of the answer document are determined (step 203).

In collation processing 106, answer document analysis processing 1
The correspondence between the document item of the answer determined in step 05 and the document item of the correct document stored in the correct expression storage unit 101 is performed. In the inspection process 107, the information of each associated document item is compared, the difference is extracted as an error, and correction is performed in the correction process.

A problem relating to the actual creation of a business document will be described with reference to FIGS. 301 in FIG.
Are presented to the learner. Assume that the learner inputs an answer document as shown in FIG. Here, the input history extraction processing 104 extracts information for the line editing function from the input history such as the keying content and the mouse event. The line editing function positions the cursor on the character string to be moved, and automatically arranges the character string in a layout such as "right alignment", "left alignment", or "center alignment".

As a result of the input history extraction processing 104, the operation contents of the character string on which the line editing operation has been performed as shown in FIG. When the learner finishes inputting the answer, the answer document is passed to the answer document analysis processing 105. In the answer document analysis processing 105, first, the answer document is divided into character strings based on delimiters. If blanks and line feeds are used as delimiters, the answer document is divided into character strings as shown in FIG. Further, an input history storage unit 1 as shown in FIG.
The document item of the answer document is determined based on the input history stored in No. 02 and the respective character strings (601 to 622) in FIG. In this example, 605 and 616 must be linked and determined as one document item.

However, in the conventional method, when a long character string continues over a plurality of lines, or when a left-aligned character string follows the long line, the document item is determined as a continuation line. When long character strings are described consecutively as in 604 and 605 in FIG. 6, it is regarded as a continued sentence, and 6
04, 605, and 616 were determined to be one document item. Therefore, the character string that the learner intentionally arranged by line editing operation is considered to be independent of other character strings,
If these character strings are preferentially determined as document items, the answer document is divided into document items as shown in FIG.

FIG. 8 is a diagram showing data stored in the correct answer expression storage means 101. In the collation processing 106, FIG.
And 701 to 72 determined in the answer document analysis processing 105.
The document item of the answer document 1 is collated with the document item. Here, if importance is attached to the similarity of characters, a collation result as shown in FIG. 9 is obtained. In the inspection process 107, the correct expressions of the associated document items are compared, and differences are extracted as errors. If the verification destination of the document item of the correct answer document does not exist in the answer document, an error of insufficient description is extracted. Conversely, if the collation destination of the document item of the answer document is not in the correct answer document, an error of a redundant description is extracted. In this example, errors such as “wrong title of“ everyone ”is written as“ sama ”” and “wrong writing of“ writing ”” are extracted, and correction is performed on the learner in correction processing 108.

By incorporating the intention information at the time of input by the learner as in the above method, the document items can be extracted more accurately, and accurate correction instruction can be provided.

When the question being addressed is the first question (step 1101), nothing is displayed in the answer area. A problem is presented in a problem presentation process 1006 (step 110).
6) The learner inputs an answer in the answer area (step 1107).

In the correction instruction 1007, an error of the answer document of the learner is extracted (step 1108). If the answer is correct (step 1109), the correct answer expression storing process 1008 is performed by the correct answer expression storing means 1002 as the correct answer expression.
To memorize. If the answer is incorrect (step 1109), the correction is made (1110), and the learner is asked to make a correction, leading to a correct answer.

A problem relating to the actual creation of a business document will be described as an example with reference to FIGS. Problems (1201 to 1204) as shown in FIG. 12 are stored in the problem storage unit 1001. The question selection process 1003 selects the question 4 of 1204 which has not been worked on yet, and extracts it from the question storage means 1001. In the comparison process 1004,
An arbitrary correct answer expression is selected from the correct answer expression storage means 1002, and the selected correct expression and the extracted correct expression (1304 in FIG. 39) of the extracted question 4 are compared for each document item, and the same character string is obtained. Is extracted. In this example, it is assumed that the most similar expression (1304 in FIG. 39) of Question 4 is selected as a comparison target.

Here, the similarity = (the number of document items of the same expression as that of the problem 4) / (the number of document items of the correct expression), and the one having the highest similarity is to be compared. In the correct answer expression 1401 of the question 1 and the correct expression 1304 of the question 4, the document items having the same expression are “title”, “writing”, “item number 1”, “item name“ date and time ””, and “item number”. 2 ”,“ item name “place” ”,“ item number 2 ”,“ item name “material” ”,“ more than ”,“ in charge ”, and“ telephone number ”. 25 = 0.44. Similarly, the correct answer expression 1402 of the question 2 and the correct answer expression 13 of the question 4
04 has a similarity of 11/25 = 0.44, and the similarity between the correct answer expression 1403 of question 3 and the correct expression of question 4 is 12/22 ≒ 0.55. Expression 1403 is selected.

In the extraction of the same character string of the correct answer expression 1403 of the problem 3 and the correct expression 1304 of the problem 4, when there are a plurality of correct expressions such as the document item name “body”, the respective correct expressions are compared. The one having the same character string more often shall be adopted.
