See 1).

Japanese Unexamined Patent Publication No. 2019-040467

In recent years, a system that recognizes the amount stated on the invoice and manages the recognized amount by a computer has been used. If the amount stated on the invoice is not correctly recognized, the correct amount will not be registered in the computer that manages the invoice, which will hinder the accounting process. With conventional technology, if the misrecognition applies to the misrecognition pattern, the amount may be corrected correctly, but if the misrecognition does not apply to the misrecognition pattern, you notice that the misrecognition has occurred. There was a problem that the wrong amount of money might be registered without it.

Therefore, the present invention has been made in view of these points, and an object thereof is to improve the accuracy of the amount of money registered in the computer that manages the invoice.

The data processing device of the first aspect of the present invention corresponds to a data acquisition unit for acquiring invoice data, a total invoice amount included in the invoice data, and a plurality of products included in the invoice data. Warning when the comparison result by the comparison unit does not match the comparison unit that compares the total billing amount and the total amount of the plurality of product amounts with the amount specification unit that specifies the plurality of product amounts. It has an output unit that outputs information.

The invoice data includes a first invoice data in which the total invoice amount is described and a second invoice data in which the details of the plurality of products are described, and the comparison unit includes the first invoice. The plurality of products included in the second invoice data including the total invoice amount included in the invoice data and the invoice number associated with the invoice number described in the first invoice data. It may be compared with the total amount of the amount.

The comparison unit may calculate the total amount by summing up the plurality of product prices described in the direction in which the character strings indicating the names of the plurality of products are arranged in the invoice data.

The invoice data includes a tax-excluded amount and a tax amount associated with each of the plurality of products, and the comparison unit adds up the tax-excluded amount and the tax amount corresponding to each of the plurality of products. Therefore, the total amount may be calculated.

The invoice data includes a tax-excluded amount and a tax amount associated with each of the plurality of products, and the comparison unit is a total of the plurality of tax-excluded amounts corresponding to the plurality of products. The output is obtained by comparing each of the first total amount and the second total amount, which is the total amount of the plurality of tax-excluded amounts corresponding to the plurality of products and the plurality of the tax amounts, with the total billed amount. The unit may output the warning information when both the comparison result between the first total amount and the total billing amount and the comparison result between the second total amount and the total billing amount do not match.

When the comparison result between the first total amount and the total billing amount or the comparison result between the second total amount and the total billing amount match, the output unit may use the first total amount or the second total amount. Information indicating which of the amounts matches the total billed amount may be output.

If the comparison results do not match, the output unit may output information indicating which of the plurality of product prices and the total billed amount may be erroneous. ..

The comparison unit determines the amount of the plurality of products based on the result of comparing the amount based on the result of multiplying the unit price and the quantity of each of the plurality of products included in the invoice data with the amount of the product. It is determined whether or not there is an error in any of the products, and when the comparison unit determines that there is an error in any of the plurality of product prices, the output unit has an error in any of the plurality of product prices. When the comparison unit determines that there is no error in any of the plurality of product prices, the information indicating that there is a high probability that the total billing amount is incorrect is output. You may.

When the comparison unit determines that the total billing amount may be erroneous, the output unit may output the total amount as a candidate for a correction amount of the total billing amount.

When the comparison unit determines that one of the plurality of product prices may be incorrect, the output unit may have an error in one or more of the plurality of product prices. The correction amount candidate may be output.

The data processing method according to the second aspect of the present invention includes a step in which a computer acquires invoice data, a total invoice amount included in the invoice data, and a plurality of products included in the invoice data. A step of specifying a plurality of corresponding product amounts, a step of comparing the total billed amount and the total amount of the plurality of product amounts, and a step of outputting warning information when the comparison results do not match. And execute.

It is a figure which shows the example of the invoice data which output the information which shows that it is highly probable that there is an error in the product price. It is a flowchart which shows the flow of the amount check process in the data processing apparatus 1.

[Overview of data processing system S]
FIG. 1 is a diagram for explaining the configuration of the data processing system S. The data processing system S is a system for processing the invoice data obtained by reading the invoice. The invoice data is data created by reading the invoice, and is data including an image showing the contents of the invoice or a plurality of text data corresponding to a plurality of character strings included in the invoice.

The data processing system S includes a data processing device 1, an accounting terminal 2, and an employee terminal 3. The data processing device 1, the accounting terminal 2, and the employee terminal 3 transmit and receive data via the network N. The network N includes, for example, the Internet or an intranet.

The data processing device 1 is a computer that manages various invoice data. The data processing device 1 may acquire a file containing the image data of the invoice from the accounting terminal 2 or the employee terminal 3 and create the invoice data based on the character string specified in the acquired image data. , The file containing the invoice data may be acquired from the accounting terminal 2 or the employee terminal 3.

The data processing device 1 according to the present embodiment manages invoice data indicating the contents of the invoice received by the billing company. The data processing device 1 stores an invoice database including the contents of invoices received by the invoiced company in the past and a plurality of past invoice data indicating the departments related to each invoice, and the accounting terminal 2 The contents of the stored invoice data are provided to the accounting terminal 2 in response to the request from. The data processing device 1 may recognize the character string included in the invoice data and output the data registered in the database of the system that manages the invoice data (for example, the core system for accounting).

The data processing device 1 uses artificial intelligence, for example, to recognize a character string included in the image data of the invoice and create the invoice data, but there are cases where the character string cannot be recognized correctly. There may also be a typographical error in the invoice. If a misrecognized or miswritten character string is registered in the database, the accounting process will be hindered. The data processing device 1 compares the total invoice amount included in the invoice data with the plurality of product amounts corresponding to the plurality of products included in the invoice data so as not to interfere with the accounting processing. By doing so, it is determined whether or not there is an erroneously recognized or erroneously written character string. The data processing device 1 calls attention to the accounting staff by outputting warning information when it detects that there is an erroneously recognized character string or an erroneously written character string. The data processing device 1 may output a character string candidate presumed to be correct when it detects that there is an erroneously recognized or erroneously written character string.

The accounting terminal 2 is a computer used by an employee (for example, an accounting person) who uses the data processing device 1 in the billing company that received the invoice. The accounting terminal 2 transmits and receives various data to and from the data processing device 1 via, for example, an intranet.

The accounting terminal 2 transmits, for example, the image data of the invoice read by the accounting staff with a scanner to the data processing device 1. Further, the accounting terminal 2 accesses the invoice database stored in the data processing device 1 according to the instruction of the accounting person, and displays the invoice data designated by the accounting person. Although FIG. 1 shows one accounting terminal 2, a plurality of accounting terminals 2 may access the data processing device 1.

The employee terminal 3 is a computer used by an employee of a billing company that has ordered a product or the like from the billing company. When the employee receives the invoice, the employee terminal 3 transmits the image data of the invoice to the data processing device 1 according to the operation of the employee.

2 and 3 are diagrams showing an example of an invoice. FIG. 2 shows an example of the invoice portion of the invoice, and FIG. 3 shows an example of the detail portion of the invoice. The main points of the description are described in the book, for example, the total billing amount of the amounts of the plurality of products described in the description is described. In the example shown in FIG. 2, the "purchase amount" which is the total amount of tax-excluded amounts of the plurality of products shown in the specification shown in FIG. 3 and the "consumption tax amount" which is the total amount of the consumption tax amounts of the plurality of products. , And the total billed amount, which is the sum of the "purchased amount" and the "consumption tax amount", is described as the "billed amount".

In the details shown in FIG. 3, the delivery date, product name, quantity, unit price, product price, and tax amount of each of the plurality of products are described. In addition, a subtotal of the product amount and a subtotal of the tax amount of a plurality of products are also described, and the total amount, which is the total amount of these items, is described as the "billed amount".

FIG. 4 is a diagram showing an example of invoice data created by reading the invoice invoice shown in FIG. The data processing device 1 causes, for example, the accounting terminal 2 to display the invoice data shown in FIG.

In the invoice data shown in FIG. 4, the total invoice amount is read as 89,000 yen, and a warning "There is a possibility of 88,000 yen" is displayed. The data processing device 1 compares, for example, the total invoice amount shown in FIG. 4 with the total value of a plurality of product amounts in the invoice data obtained by reading the invoice shown in FIG. 3, and warns when these do not match. Is displayed on the accounting terminal 2. At this time, as a candidate for the correct total billing amount, the total value of the plurality of product amounts described in the statement is displayed on the accounting terminal 2 as a correction amount candidate.

When the tax-excluded amount and the tax amount are described in the data processing device 1, the data processing device 1 displays a warning based on the result of comparing the total amount of the tax-excluded amount and the tax amount with the total billed amount, or a correction amount candidate. May be displayed. By displaying the warning on the accounting terminal 2 in this way, the data processing device 1 can recognize that there is a problem with the invoice data. Further, the data processing device 1 displays the correction amount candidate, so that the accounting staff can easily correct the correction amount.

FIG. 5 is a diagram showing an example of invoice data created by reading the invoice details shown in FIG. In the invoice data shown in FIG. 5, the "invoice amount" is erroneously read as 98,000 yen, and a warning is displayed. In the data processing device 1, the amount described as the "billed amount" is 88,000 yen, which is the sum of the total amount of 80,000 yen for a plurality of product amounts and the total amount of 8,000 yen for the tax amount. Since we have not done so, we will determine that there may be an error in the amount stated as "billed amount" and output a warning. The data processing device 1 may output a warning based on the fact that it does not match the total billing amount stated in the book.

As described above, in the data processing device 1, when the total invoice amount included in the invoice data and the total amount of the plurality of product amounts corresponding to the plurality of products included in the invoice data do not match. Since it outputs a warning, the accountant recognizes that the amount in the invoice has been read incorrectly. As a result, it is possible to prevent incorrect amounts from being registered in the database. Hereinafter, the configuration and operation of the data processing device 1 will be described in detail.

[Configuration and operation of data processing device 1]
FIG. 6 is a diagram showing the configuration of the data processing device 1. The data processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 includes a data acquisition unit 131, a character string specifying unit 132, an amount specifying unit 133, a comparison unit 134, and an output unit 135.

The communication unit 11 has a communication controller for transmitting and receiving various data to and from the accounting terminal 2 and the employee terminal 3 via the network N. The communication unit 11 inputs data received from, for example, the accounting terminal 2 to the data acquisition unit 131. Further, the communication unit 11 transmits the data input from the output unit 135 to, for example, the accounting terminal 2.

The storage unit 12 has a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a hard disk. The storage unit 12 stores a program executed by the control unit 13. The storage unit 12 also functions as a work memory for temporarily storing the image data of the invoice received via the communication unit 11. The storage unit 12 may store the invoice data of the past invoice.

The control unit 13 has, for example, a CPU (Central Processing Unit). The control unit 13 functions as a data acquisition unit 131, a character string specifying unit 132, an amount specifying unit 133, a comparison unit 134, and an output unit 135 by executing a program stored in the storage unit 12.

The data acquisition unit 131 acquires various data via the communication unit 11. The data acquisition unit 131 acquires invoice data transmitted from, for example, the accounting terminal 2 or 3. When the acquired invoice data is image data, the data acquisition unit 131 inputs the image data to the character string specifying unit 132. The data acquisition unit 131 may store the image data of the invoice in the storage unit 12. When the acquired invoice data includes text data, the data acquisition unit 131 inputs the invoice data to the amount specifying unit 133.

Further, the data acquisition unit 131 may acquire data indicating the operation contents of the accounting terminal 2. The instruction data is, for example, selection data indicating a candidate character string selected by the accounting staff of the accounting terminal 2 from a plurality of candidate character strings. The data acquisition unit 131 notifies the amount identification unit 133 of the acquired selection data.

The character string specifying unit 132 specifies a plurality of character strings included in the image data of the invoice. The character string specifying unit 132 identifies a plurality of character strings by recognizing characters using, for example, OCR (Optical Character Recognition). As an example, the character string specifying unit 132 learns a combination of an image data in which a character is read and a character string as teacher data, and outputs a plurality of character strings corresponding to the input image data (that is, a machine learning model (that is,). By inputting the image data of the invoice into the artificial intelligence engine), multiple character strings are specified. The character string specifying unit 132 notifies the amount specifying unit 133 of the specified character string.

When the invoice is composed of an invoice and a statement, and the image data of the invoice includes the invoice data (first invoice data) and the statement data (second invoice data), the character string identification unit. The 132 may further determine whether the read image data of the invoice is the data of the book or the data of the details, and may notify the amount specifying unit 133 of the determination result. For example, when the character string specifying unit 132 cannot specify the character strings of a plurality of product names, it determines that the image data of the read invoice is the data of the book, and specifies the character strings of the plurality of product names. If it can be done, it is determined that the image data of the read invoice is the data of the details. The character string specifying unit 132 inputs the invoice data read into the model machine-learned using the format of the book and the format of the details as teacher data in advance, and the read invoice is based on the result output from the model. It may be determined whether it is a reference or a detail.

Based on the specified character string, the character string specifying unit 132 includes the first billing data and the second billing data corresponding to one bill among the plurality of first billing data and the plurality of second billing data. May be specified. When the second invoice data includes the invoice number associated with the invoice number described in the first invoice data, the character string specifying unit 132 may refer to, for example, the first invoice data and the first invoice data. 1 The second invoice data including the invoice number corresponding to the invoice number described in the invoice data may be determined to be the data of the reference and the data of the details included in one invoice data. ..

In the case of the example shown in FIGS. 2 and 3, the second invoice data includes the same invoice number as the invoice number S1000226 included in the first invoice data, and the first invoice data shown in FIG. 2 is , It is determined that the second invoice data is a reference shown in FIG. The character string specifying unit 132 notifies the amount specifying unit 133 of the type information indicating which invoice data corresponds to the invoice and which invoice data corresponds to the details.

The amount specifying unit 133 specifies the total invoice amount included in the invoice data and the plurality of product amounts corresponding to the plurality of products included in the invoice data. The amount specifying unit 133 specifies, for example, that the amount included in the book is the total billed amount based on the type information notified from the character string specifying unit 132, and in the same column or the same column as a plurality of product names in the statement. Identify that the amounts listed on the same line are multiple product amounts.

If the invoice details include the total invoice amount and multiple merchandise amounts, the amount identification unit 133 will use the location in the invoice where the amount is stated, or the text next to the amount. It may be determined whether it is the total invoice amount or the product amount based on at least one of the contents. The amount specifying unit 133 determines, for example, that the amount written at the bottom of the invoice is the total invoice amount, and that the amount written in the same column or row as the product name is the product amount. do.

The comparison unit 134 compares the total billed amount specified by the amount specifying unit 133 with the total amount of the plurality of product amounts. The comparison unit 134 is included in, for example, the total invoice amount included in the first invoice data corresponding to the invoice shown in FIG. 2 and the second invoice data corresponding to the details shown in FIG. Compare with the total amount of multiple product prices. The comparison unit 134 adds up the total amount of the plurality of products described in the direction (vertical direction in the example shown in FIG. 3) in which the character strings indicating the names of the plurality of products are arranged in the invoice data. Is calculated. The comparison unit 134 notifies the output unit 135 of the comparison result. When the total invoice amount and the plurality of product amounts are described in the invoice statement, the comparison unit 134 compares the total invoice amount described in one item with the total amount of the plurality of product amounts. You may.

The output unit 135 outputs warning information when the comparison results of the comparison unit 134 do not match. The output unit 135 may output the difference between the total billed amount and the total amount of the plurality of product amounts when the comparison results do not match. If the output unit 135 determines that the total billing amount may be incorrect, the output unit 135 may output the total amount as a candidate for the correction amount of the total billing amount. The output unit 135 causes the accounting terminal 2 to display the warning information, the difference amount, or the correction amount candidate by, for example, transmitting the warning information or the correction amount candidate to the accounting terminal 2, but the output unit 135 is connected to the data processing device 1. Warning information, difference or correction amount candidates may be displayed on the displayed display, or warning information, difference or correction amount candidates may be printed on paper.

Hereinafter, the operations of the comparison unit 134 and the output unit 135 will be described in detail.
As in the example shown in FIG. 3, when the tax-excluded amount and the tax amount of the product are described separately in the statement, the comparison unit 134 shall add up the tax-excluded amount and the tax amount corresponding to each of the plurality of products. Calculate the total amount by. The comparison unit 134 is a first total amount that is the total amount of a plurality of tax-excluded amounts corresponding to a plurality of products, and a second total amount that is a total amount of a plurality of tax-excluded amounts and a plurality of tax amounts corresponding to a plurality of products. You may compare each of the total amounts with the total invoiced amount. In this case, the output unit 135 outputs warning information when both the comparison result between the first total amount and the total billing amount and the comparison result between the second total amount and the total billing amount do not match, and one of them is output. If the comparison results of are the same, no warning information is output. By operating the comparison unit 134 and the output unit 135 in this way, for example, when the total billing amount including tax is described in the book and the tax-excluded amount for each product is described in the statement, someday. It is possible to prevent the comparison unit 134 from erroneously determining that the value is incorrect and the output unit 135 to output warning information.

Further, in the output unit 135, when the comparison result between the first total amount and the total billing amount or the comparison result between the second total amount and the total billing amount match, either the first total amount or the second total amount is the total. Information indicating whether the amount matches the billed amount may be output. For example, when the output unit 135 determines that the first total amount and the total billing amount match, the accounting terminal 2 displays "the total billing amount described in the book is the tax-excluded amount", and the second When it is determined that the total billing amount and the total billing amount match, "the total billing amount stated in the book is the tax-included amount" is displayed on the accounting terminal 2. By outputting such information by the output unit 135, when the tax-excluded amount is described in the book, the accounting staff recognizes that the total billed amount described in the book is the tax-excluded amount. Can be processed.

If the comparison result between the total amount of the plurality of product amounts and the total billing amount does not match, the output unit 135 may have an error in one of the plurality of product amounts or the total billing amount. Information indicating the above may be output. In order to make this possible, the comparison unit 134 is based on the result of comparing the amount based on the result of multiplying the unit price and the quantity of each of the plurality of products contained in the invoice data and the product amount. It is determined whether or not there is an error in any of the product prices of. When the comparison unit 134 determines that one of the plurality of product prices is incorrect, the output unit 135 outputs information indicating that there is a high probability that one of the plurality of product prices is incorrect. Further, when the comparison unit 134 determines that there is no error in any of the plurality of product prices, the output unit 135 outputs information indicating that there is a high probability that the total billed amount has an error.

FIG. 7 is a diagram showing an example of invoice data in which information indicating that there is a high probability that the product price is incorrect is output. The comparison unit 134 compares the amount obtained by multiplying the quantity and the unit price, the product amount, and the tax amount for each product. In the case of the example shown in FIG. 7, in the comparison unit 134, the amount of 20,000 yen, which is the product of the quantity of the “probe for measuring instrument A” and the unit price, does not match the product price, and the tax amount is 2,000 yen. Since it is consistent with the above, it is judged that there is a high possibility that the product price "30,000 yen" is incorrect. Then, the comparison unit 134 determines that it is highly probable that the product amount is "20,000 yen" based on either the amount obtained by multiplying the quantity and the unit price or the tax amount. When the output unit 135 determines that there is a possibility that one of the plurality of product prices is incorrect, the output unit 135 is a candidate for the correction amount of one or more product prices that may be incorrect among the plurality of product prices. Is output. In the example shown in FIG. 7, the output unit 135 outputs the information "there is a possibility of 20,000 yen".

The comparison unit 134 has the quantity, unit price, and product amount associated with each of the plurality of products, provided that the total billed amount described in the book and the total amount of the plurality of product prices described in the statement do not match. , And whether the tax amount is consistent with other amounts listed in the same column or row. By operating the comparison unit 134 in this way, only when there is a possibility that one of the amounts described in the item is incorrect, the consistency of the amount described in the item is checked. It is possible to shorten the processing time when the total billed amount described and the total amount of the plurality of product amounts described in the statement match.

By the way, in the above description, it is assumed that the data of the invoice and the data of the details included in the invoice data are the data corresponding to the invoice and the details included in the same invoice. However, due to a mistake made by the person who read the invoice, the invoice data and the detail data contained in the invoice data may be different invoices and details. Therefore, in order to be able to detect such an error, the output unit 135 has an error in character recognition due to the difference between the total billing amount described in the book and the total amount of the plurality of product amounts described in the statement. If it is determined that the above is not the case, warning information may be output indicating that the description and the details may not match.

Since the character recognition rate in recent years is 99% or more and the probability that multiple characters are erroneously recognized is low, the comparison unit 134 compares the total billed amount with the total amount of a plurality of product amounts, and as a result, a plurality of numerical values are used. If they do not match, it may be determined that the book and the details may not match. By operating the comparison unit 134 and the output unit 135 in this way, the accounting staff can understand that an error has occurred in the process of reading the invoice containing the invoice and the details, so that incorrect data can be stored in the computer. You can prevent it from being registered.

[Processing flow of data processing device 1]
FIG. 8 is a flowchart showing the flow of the amount check process in the data processing device 1. The flowchart shown in FIG. 8 starts from the time when, for example, the accounting staff performs a process of registering the image data of the invoice in the data processing device 1.

The data acquisition unit 131 acquires the image data of the invoice transmitted by the accounting terminal 2, and inputs the acquired image data to the character string specifying unit 132 (S11). The data acquisition unit 131 may acquire the invoice data after the character string is specified, and may notify the acquired invoice data to the amount identification unit 133. The character string specifying unit 132 specifies a character string included in the input image data, and notifies the specified character string to the amount specifying unit 133 (S12).

The amount specifying unit 133 specifies the total billed amount based on the character string described in the book (S13). Further, the amount specifying unit 133 specifies a plurality of product prices based on the plurality of character strings notified as the character strings described in the details (S14). The comparison unit 134 compares the total billed amount with the plurality of product amounts (S15).

When the comparison unit 134 determines that the comparison results match (YES in S16), the comparison unit 134 ends the amount check process. When the comparison unit 134 determines that the comparison results do not match, the comparison unit 134 notifies the output unit 135 of the determination result, and the output unit 135 outputs warning information (S17). When the comparison unit 134 can calculate the correction amount candidate (YES in S18), the output unit 135 further outputs the correction amount candidate (S19). When the comparison unit 134 cannot calculate the correction amount candidate (NO in S18), the output unit 135 ends the process.

[Effect of data processing device 1]
As described above, in the data processing device 1, the total invoice amount included in the invoice data and the total amount of the plurality of product amounts corresponding to the plurality of products included in the invoice data do not match. Since the warning information is output in the case, the accounting staff recognizes that the amount in the invoice is read incorrectly. As a result, it is possible to prevent incorrect amounts from being registered in the database.

The data processing device 1 outputs warning information when, for example, the total invoice amount described in the invoice and the total amount of the plurality of product amounts described in the invoice details do not match. Therefore, in the output unit 135, in addition to the case where the character string specifying unit 132 misrecognizes the character string, the total invoice amount and the total amount do not match due to the mixture of different invoices and details. Also, warning information can be output. As a result, it becomes possible for the accounting staff to know that an error has occurred in the process of reading the invoice containing the invoice and the details.

Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes can be made within the scope of the gist. be. For example, all or part of the device can be functionally or physically distributed / integrated in any unit. Also included in the embodiments of the present invention are new embodiments resulting from any combination of the plurality of embodiments.
