2. Description of the Related Art Conventionally, in a local government or the like, when computerizing family register work, it was necessary to remanufacture a paper-based unregistered register (dirt removal, smearing, trimming, supplementary writing, etc.). Reproduction of such an expulsion original book is generally carried out by a trader, but in this reproduction operation, there are cases where the characters etc. described in the expulsion original book cannot be understood. In such a case, the business operator made a question inquiry to the staff such as the local government. By the way, the characters used for family register are unique,
When remanufacturing the expulsion ledger, it is necessary to remanufacture the characters of the expulsion original book as it is, and even when inquiring about doubts, the characters (figure) that do not have character fonts and character codes handled by general computers are managed as they are. Had to do.

An outline of a conventional paper-based inquiry system for inquiries will be described with reference to FIGS. 11 and 12. In the following description, the case of “city” as a local government will be described. First, a collective management type inquiry system will be described with reference to FIG. In the conventional batch inquiry type inquiry system, the issuer of question creates an inquiry sheet describing the details of the inquiry (step S7).
1) Send to a person in charge of inquiry on the side of city hall (hereinafter referred to as person in charge of inquiry) by a facsimile machine or the like (step S72). When the suspicious person accepts the suspicion vote (step S73), the suspicion officer sorts the suspicion vote to a plurality of respondents (persons in charge of family register in the city hall or branch) under the control of the person in question (step S73). S74), and sends to each respondent by facsimile or the like (step S75). Respondents who have received the question form will investigate the question form (step S7).
6). Here, the investigation refers to referring to the result of the investigation of the question sheet previously performed, to fill in the expulsion register corresponding to the question sheet, and to refer to other expulsion original books prepared by the person in charge of preparation. Say.

Based on the result of this survey, the respondent prepares a reply sheet to the contents of the doubt (step S77) and sends it to the person in charge of doubt by facsimile or the like (step S78). In parallel with this, the respondent manages and files the doubt sheet and the corresponding reply sheet (step S7).
9). The person in charge of suspicion, who received the response form from the respondent, checks whether the response form is inconsistent with the previous response form or whether there is an error, and if it determines that there is no problem, approves the response ( Step S80). And
Regarding the approved answer sheet, the answer sheet is sent by facsimile or the like to the question issuer corresponding to the answer sheet (step S81). In parallel with this, the person in charge of doubt manages and files the doubtful vote and the corresponding approved answer sheet (step S82). On the other hand, the suspicion issuer who received the answer sheet was supposed to remanufacture the expulsion register based on the obtained answer sheet, and to manage and file the received answer sheet (step S83).
In this case, the question issuer, the responsibility for the question, and the management and filing of the reply sheet by the respondent are managed so that the contents are the same. In the above-mentioned integrated inquiry system inquiry system, the person in charge of the inquiry can grasp the entire inquiry operation and can answer as a unified view of the city side, and the advantage of being more clear where the responsibility is there were.

Next, a distributed management type inquiry system will be described with reference to FIG. In the conventional decentralized management type inquiry system, the issuer creates a question sheet in which the content of the question is written (step S91), and among the plurality of respondents on the city hall side, the removal register corresponding to the question sheet It is sent to the respondent who manages the above by a facsimile machine or the like (step S92). Each of the respondents who received the question form investigates the question form (step S93), creates an answer sheet for the content of the question based on the result of the investigation (step S94), and sends it to the question issuer by facsimile or the like. Yes (step S95). In parallel with this, the respondent manages and files the doubt sheet and the corresponding reply sheet (step S96). On the other hand, the suspicious issuer who received the response is supposed to remanufacture the expulsion register based on the obtained response, and to manage and file the received response (step S
97). Even in this case, the management and filing of the reply sheet by the question issuer and the respondent are managed so that the contents are the same.

[0006]

In each of the above-mentioned inquiry systems, since a question inquiry is made using paper such as a facsimile, a large amount of documents are generated. In addition, since the inquiry inquiry is managed with documents, it is not possible to easily understand what kind of inquiry inquiry was made and what kind of response was made, which in turn makes it difficult to manage history or search when conducting an investigation. There was a problem that it cost. Furthermore, if the filing status is incorrect in both the issuer and the respondent (and the person in charge of doubt), it is not possible to effectively manage the inquiry of doubts and to function as the final verification document. There was a problem. Further, in the suspicion inquiry system of the collective management method, there is a problem that each of the suspicion issuer, the suspicion manager, and the respondent must manage documents, and tens of thousands of papers.

Further, in the suspicion inquiry system of the collective management system, the responsibility for managing documents is concentrated on the suspicious person, so that it takes time to grasp and manage the response status and progress status, and the actual system operation. There was a problem that there was a problem. Also, in the case of a distributed management type inquiry system, the management burden on the city hall side can be reduced compared to the above-mentioned batch management type inquiry system, but it is difficult to keep the level of respondents constant. Therefore, there is a possibility that the reply content of the answer sheet may vary. Furthermore, there was a problem that the issuer of doubts had to grasp the entire inquiry inquiry work. Therefore, an object of the present invention is to provide a handwritten character management device and a handwritten character management method that can suppress the generation of documents, simplify the management of handwritten characters, and reliably manage the handwritten characters. An object of the present invention is to provide a handwritten character inquiry system and a handwritten character inquiry method that can perform a character inquiry quickly and reliably.

[2.3] Database Configuration in the Inquiry Inquiry Server Next, the configuration of the database in the inquiry inquiry server will be described. As shown in FIG. 3, the database in the inquiry inquiry server 32 includes an inquiry form database (DB) 32A for accumulating inquiry forms and an identical character database (DB) 32B for storing a plurality of characters recognized as the same character.
And a similar figure database (DB) 32C that stores a plurality of characters that are similar to a certain character, and a handwritten character file folder 32D that stores the figure data corresponding to the handwritten character. There is. [2.3.1] Outline of Handwritten Character Management First, an outline of handwritten character management will be described. The relationship between handwritten characters is managed by the same character database 32B and the similar figure database 32C described above. More specifically, in the same character database 32B, as shown in FIG. 4, data (management code) about a character that can be regarded as the same as a character serving as a key using a certain character (“A” in FIG. 4) as a key. Data and graphic file name) are managed as the same character record RS. Also, the similar figure database 32
In C, a character (in FIG. 4, “O”, “me”,
“Wa” and “cheap”) are used as keys and the data (management code data and graphic file name) about the characters similar to the key are managed as similar graphic records RL along with the similarity ratio with the key characters. Has been done.

Then, the same character database 32B is
The similar figure database 32C is linked based on the data about the characters that can be regarded as the same as the key characters. Also, in the similar figure database 32C,
It is configured to have a correlation with a character corresponding to specific management code data. More specifically, for example, FIG.
As shown in, when the recognition result of the handwritten character is the character "A", it is registered as the character of the management code "A-5" in the same character database 32B and the management code in the similar figure database 32C. The similar figure record corresponding to "O-2" is registered, and the management code "O-2" is registered as the similar figure record RL corresponding to the management code "Wa-1". In this way, the same character database 32B and the similar figure database 32
In C, the links are formed in a mesh shape based on the similarity ratio. FIG. 6A shows an example of the record format of the same character record on the same character database 32B.

The same character record RS includes the character RS1 as a key and the graphic file names RSG1 to RSGn associated with the management codes RSC1 to RSCn and the management codes RSC1 to RSCn for the characters that can be regarded as the same as the key. It is composed by. More specifically, the key character RS1 is the character "a" recognized by the character recognition, and the management codes RSC1 to RSC
As n, for example, "a-1", "a-2", "a-"
3 ”,“ A-4 ”, ...,“ A-n ”, and the graphic file names RSG1 to RSGn are, for example,“ A-
1. GIF ”,“ A-2.JPG ”,“ A-3.JP ”
G "," A-4.BMP ", ...," A-n.GIF "
Is. FIG. 6B shows an example of the record format of the similar figure record on the similar figure database 32C. The similar figure record RL has a management code RLC.
And the key RLK of the character to which the character corresponding to the management code RL1 belongs, the graphic file name RLG corresponding to the management code RL1, and the same character represented by the key RLK of the character to which the character corresponding to the management code RL1 belongs. Management codes RLC1 to RLC of similar characters not belonging to record RS
n, the graphic file names RLG1 to RLGn corresponding to the similar character management codes RLC1 to RLCn, and the similarity ratio RLR1 between the characters corresponding to the management code RLC and the similar characters.
To RLRn.

More specifically, the management code RLC is "A-1", the key RLK of the character to which the character corresponding to the management code RLC belongs is "A", and the graphic file name RLG is "A-1.GIF". Furthermore, management codes RLC1 to RLCn of similar characters
And similar graphic file names RLG1 to RLGn,
The similarity ratios RLR1 to RLRn are managed as one set, and the graphic file name RLG1 = “O-3.GIF” corresponding to the management code RLC1 = “O-3” of similar characters.
And the similarity ratio RLR1 = 70 [%]. Similarly, the graphic file name RLG2 = “me-2.JPG” corresponding to the similar character management code RLC2 = “me-2”, the similarity ratio RLR2 = 64 [%], and the similar character management code RLCn. = Graphic file name RLGn corresponding to “Chi-4” = “Ci-4.BMP”, and the similarity ratio R
LRn1 = 52 [%]. Since the handwritten characters are managed as graphics as described above, it can be expected that the characters having the characteristics and habits of a particular writer will be gathered in a related group, and an accurate answer about the handwritten characters can be obtained. it can. For example, as shown in FIG.
The similarity ratio is lower between the character "Fuji" that is Mr. and the character "rattan" where the writer is Mr. B, but the similarity ratio is higher between the character "Fuji" and the character "rattan" where Mr. A is the writer. , Will be treated as similar figures. Moreover, once a figure with a high similarity ratio is hit, it is possible to expand the search target centering on the hit figure, so all cases are compared with the figure of the character recognized for the first time. It is not necessary, and even patterns that are unlikely to be similar are not used for comparison and comparison, and the extraction time of similar patterns can be made relatively short.

[2.4] Handwritten Character Data Addition Process Next, the handwritten character data addition process will be described with reference to the data flow charts of FIGS. 8 and 9. [2.4.1] When the same character record exists The handwritten character addition process when the same character record exists will be described with reference to FIG. When a handwritten character is input (step S1), character recognition is performed on the input handwritten character to identify the character (step S).
2). In the case of FIG. 8, the identified character is “A”. The same character database 32B is referred to for the specified character, and the presence or absence of the same character record RS is checked (step S3). In the case of the above example, it is checked whether or not there is a record corresponding to the character "a".

Since the same character record exists in the determination in step S3, a new management code RSCn is added to the figure corresponding to the character, and the figure file name RSGn corresponding to the handwritten character is added together with the same character database. 32B (step S4). Further, the graphic file with the graphic file name corresponding to the handwritten character is stored in the storage diagram file folder 32D. More specifically, in the above example, since the same character record RS corresponding to the character "A" exists, a new management code RSCn is added to the newly input handwritten character, The graphic file name RSGn in which the handwritten character is stored is additionally written in the same character database 32B (step S5). In this case, as the management code RSCn, for example, in FIG. 8, "a-n" is shown as the nth record having the character "a" as a key. Various settings are possible, such as "point code + record serial number for the character."

Further, as a format of a graphic file corresponding to handwritten characters, GIF (Grap) which is generally used.
hics Interchange Format) format, JPEG (Joint Pho
Various formats such as tographic Experts Group) format and BMP format are used. Next, a new similar figure record is created in the similar figure database 32C using the new management code as a key (step S6). More specifically, a new similar figure record with the management code "A-n" as a key is created. Subsequently, the similar figure database 32C is referenced with the management code of the first record of the character to which the input handwritten character belongs as a key (step S7), and the similar figure record is acquired (step S8). More specifically, in the case of the above example, the similar figure database 32C is referred to by using the management code "A-1" of the first record of "A" as a key. Subsequently, the management code of the first record in the acquired similar figure record RL and the corresponding figure file are specified (step S
9) and obtain (step S10).

Specifically, the first similar figure of the character "A"
The management code “O-3” and the corresponding graphic file “O-3.GIF”, which is the second record, are specified. Then, from the accumulation diagram file folder 32D, “O-3.GI
The "F" file is read (step S11), and the input handwritten character graphic is compared with the graphic corresponding to the "O-3.GIF" file (step S12). Then, the input handwritten character graphic and "O-3.GIF"
The similarity ratio (for example, the degree of similarity) of the figure corresponding to the file is calculated (step S13). Then, the obtained similarity ratio is a predetermined ratio (for example, the similarity ratio 50 [%]).
If the above is the case, the management code "O-n" is stored in the area (the first area in the initial state) corresponding to the similarity ratio obtained in the similar figure record with the management code "A-n" as a key.
3 ”, the graphic file name“ O-3.GIF ”corresponding to the management code“ O-3 ”and the similarity ratio are set as new records (step S14) and added to the similar graphic database 32C (step S15). Further, based on the obtained similarity ratio, the record corresponding to the new management code is set in the area corresponding to the similarity pattern record (record of management code “Oh3” in the above example) of the similarity pattern database 32C. Add (step S16). In this case, when the number of similar figure records corresponding to the management code of the addition destination exceeds the preset number due to the addition of similar figure records, the similar figure record with the lowest similarity rate is deleted and then the similar figure record is deleted. RL will be added.

More specifically, if the similarity between the handwritten character corresponding to the management code "A-n" and the figure corresponding to the file "O-3.GIF" is 70%, the character " Since the figure records that make up the similar figure record corresponding to "a" are stored in the order of high similarity,
The management code "A-
n ”, the graphic file name of the handwritten character corresponding to the management code“ A-n ”, and the similarity ratio are added to the similar graphic database 32C as new records. Hereinafter, similar processing is performed for the second and subsequent records in the acquired similar figure record, and the processing is continued until the processing for all the records in the acquired similar figure record is completed.

[2.4.2] When the same character record does not exist Next, the handwritten character addition process when the same character record does not exist will be described with reference to FIG. When a handwritten character is input (step S21), character recognition is performed on the input handwritten character to identify the character (step S22). In the case of FIG. 9, it is assumed that the identified character is “A” and that the same character record does not correspond to “A”. For the specified character, the presence or absence of the same character record RS is checked by referring to the same character database 32B (step S23). In the above example,
It is checked whether or not the same character record RS corresponding to the character "A" exists. In the determination in step S23, since the same character record RS does not exist, a new management code is added to the graphic corresponding to the character (step S24), and the same character is stored together with the graphic file name corresponding to the handwritten character. Database 32
Add to B (step S25). Further, the graphic file with the graphic file name corresponding to the handwritten character is stored in the storage diagram file folder (step S26).

More specifically, in the above example, "a"
Since there is no record corresponding to the character, the new management code is added to the newly input handwritten character, and the handwritten character is additionally written in the same character database 32B as a graphic file stored therein. Become. In this case, as the management code, for example,
It is shown as "A-1" as the first record with the character "A" as a key, but since it is considered to correspond to a character code that does not exist in normal computer processing, "any code + the relevant character Record serial number in
Various settings such as Next, a new similar figure record is created in the similar figure database 32C using the new management code as a key (step S27). More specifically, a new similar figure record with the management code "A-1" as a key is created. Subsequently, the figure corresponding to the input handwritten character is compared with the figure stored in the storage diagram file folder to calculate a similarity ratio (eg, degree of similarity) (step S28).

Then, if a figure whose obtained similarity ratio is a predetermined ratio (for example, the similarity ratio 50 [%]) or more has the management code "O-1" as a key, the management code " With reference to the same character database 32B using "O-1" as a key (step S29), the management code "O"
To obtain the same character record RS (step S3)
0). Then, the same character record RS of the management code "O"
The similar figure database 32C is referred to by using the management code "O-1" of the first record of the key as a key (step S
31), the similar figure record RL is acquired (step S).
32). Further, the similar figure database is referenced with the management code "O-1" as a key (step S33), and the similar figure database 32C is referenced with the management code of the first record of the management code "O-1" as a key. The similar figure record RL is acquired (step S34).

More specifically, in the case of the above example, "O"
The similar figure database 32C is referred to by using the management code "wa-1" of the first record of the above as a key. Then, the management code of the first record in the obtained similar graphic record RL and the corresponding graphic file are specified (step S35) and acquired (step S3).
6). Specifically, the management code "O-1" which is the first record of the similar graphic of the management code "W-1" and the corresponding graphic file "O-1.GIF" are specified.
Then, from the accumulated diagram file folder, "O-1.GI
The file "F" is read, and the figure of the handwritten character corresponding to the management code "A-1" is compared with the figure corresponding to the file "O-1.GIF" (step S37). If the obtained similarity ratio is equal to or higher than a predetermined ratio (for example, the similarity ratio 50 [%]), the management code “wa-
The figure corresponding to the management code "A-1" and the management code "A-1" in the area (the first area in the initial state) corresponding to the similarity ratio obtained in the similar figure record whose key is "1" The file name "A-1.GIF" and the similarity rate (7 in the figure
0 (%)) is inserted as a new record (step S
38) and add to the similar figure database 32C (step S39).

Further, the management code "Wa-" is stored in the area (the first area in the initial state) corresponding to the similarity ratio obtained in the similar figure record with the management code "A-1" as a key.
1 ”, the figure file name“ wa-1.GIF ”corresponding to the management code“ wa-1 ”and the similarity rate (70 [%] in the figure) are inserted as new records (step S40), and the similar figure database 32C is inserted. To (step S4
1). Hereinafter, similar processing is performed until no record that can be acquired remains in the similar figure record.

A graphic file corresponding to a handwritten character that is a candidate for a handwritten character is selected, and the graphic file is transmitted to the person in charge terminal device to which the inquiry form data is distributed among the person in charge terminal devices 34-1 to 34-n. Thereby, the person-in-charge terminal devices 34-1 to 34-n to which the graphic file is transmitted display the graphic corresponding to the graphic file transmitted on the display as a character candidate graphic (FIG. 3 and FIG. 10 upper right part). reference). Thereby, the answerer compares the handwritten character corresponding to the question sheet data with the character candidate figure, and if the character candidate figure contains the handwritten character corresponding to the handwritten character corresponding to the question sheet data, the corresponding handwritten character The candidate data corresponding to is selected (see the lower left part of FIG. 3).

If the character candidate graphic does not include a handwritten character corresponding to the handwritten character corresponding to the question mark data, the answering person in the inquiry inquiry server 32 uses the same character database 32B or the similar figure database. 32C, search for a handwritten character corresponding to the handwritten character corresponding to the question sheet data, or conversely, enter the handwritten character corresponding to the question sheet data using tablets 35-1 to 35-n In the inquiry server 32, the same character database 32 is obtained by performing character recognition.
B or similar figure database 32C is registered. After that, the person in charge terminal devices 34-1 to 34-n support the preparation of the answer sheet, and each of the person in charge of answer prepares the answer sheet for the handwritten characters corresponding to the question sheet data (step S5).
4). Then, the answer sheet is transmitted to the terminal device for responsible person 33. When the reply is transmitted, the terminal device for responsible person 33 notifies the questionable responsible person by displaying a screen or the like. As a result, the person in charge of doubt is the terminal device 33 for the person in charge.
On the display of the answer sheet, the content of the question sheet data corresponding to the answer sheet is examined, and if there is no problem, the answer sheet is approved (step S55), and the modem function 36A of the dial-up router 36 is used. , And transmits it to the terminal device 21 for a provider via the single line 25 (step S5).
6).

In addition, if there is a problem in the content such as inconsistency with the previously created answer sheet, etc., add a comment,
It will be sent back to the corresponding terminal device for the person in charge again, and a request will be made to recreate the answer sheet.
