[Overview of information processing system S]
FIG. 1 is a diagram for explaining an overview of the information processing system S. As shown in FIG. The information processing system S is a system for supporting office processing. The information processing system S includes an information processing device 1 and an information terminal 2. The information processing device 1 and the information terminal 2 are communicably connected via a network. The information processing system S may further include a device that performs subsequent processing on the acquired data.

The information processing device 1 is a device for acquiring processing target data (hereinafter referred to as "processing target data") and mapping each item included in the acquired processing target data to data that can be exchanged on a network. It is. More specifically, the information processing device 1 stores format information. The format information will be described later, but it indicates data that can be processed by the information processing system S. The data to be processed is electronic data of documents to be processed. Examples of data to be processed include, but are not limited to, evidence such as purchase orders, delivery notes, and invoices, and contracts.

The information terminal 2 is a terminal device used by a user. The information terminal 2 transmits processing target data to the information processing device 1. Based on the information acquired from the information processing device 1, the information terminal 2 displays a screen for the user to check mapping candidates between the items of the processing target data and the items included in the format information. Note that the user of the information processing system S is a person in charge at a company that performs administrative processing using processing target data.

Processing in the information processing system S will be explained. The information processing device 1 acquires processing target data ((1) in FIG. 1). The information processing device 1 identifies a corresponding defined item for each of a plurality of items included in the processing target data ((2) in FIG. 1). As an example, the information processing device 1 identifies a corresponding defined item based on the name of the item included in the processing target data.

The information processing device 1 identifies, as unspecified items, items for which the corresponding defined items cannot be identified among the items included in the processing target data ((3) in FIG. 1). The information processing device 1 identifies the item as a candidate item corresponding to the unspecified item ((4) in FIG. 1). The candidate item is a defined item that is a candidate to which an unspecified item corresponds in the format information. As an example, the information processing device 1 identifies candidate items based on the content indicated by the defined items included in the format information, the relationship between unspecified items, and items for which the defined items have been identified. The information processing device 1 outputs candidate items ((5) in FIG. 1). As an example, the information processing device 1 causes the information terminal 2 to display unspecified items and candidate items in association with each other.

When the information processing device 1 receives an operation to confirm a candidate item as an item corresponding to an unspecified item via the information terminal 2, the information processing device 1 replaces the name of the item with the name of the candidate item. Generate processing target data. For example, the information processing device 1 may output the replaced processing target data to a device that executes subsequent processing.

By configuring the information processing system S in this way, it is possible to reduce the effort required to process data to be processed, including items for which conversion profiles are not defined in advance.

[Configuration of information processing device 1]
FIG. 2 is a block diagram showing the configuration of the information processing device 1. As shown in FIG. The information processing device 1 includes a communication section 11, a storage section 12, and a control section 13. The control unit 13 includes an acquisition unit 131 , an item identification unit 132 , a candidate identification unit 133 , an output unit 134 , and a position identification unit 135 .

The communication unit 11 is a communication interface for transmitting and receiving data to and from other devices via a network. The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an SSD (Solid State Drive), a hard disk drive, and the like. The storage unit 12 stores in advance a program to be executed by the control unit 13.

The storage unit 12 stores format information including defined items, which are a plurality of defined items. FIG. 3 is a diagram showing an example of the data structure of format information stored in the storage unit 12. The format information includes "item ID", "item name", "data type", "definition", and "related item". “Item ID” is an ID (Identificatoin) that identifies a defined item. “Item name” indicates the item name of the defined item. “Data type” indicates the data type allowed in the defined item. “Definition” indicates the content indicated by the defined item and the relationship with other items. The definition includes, for example, a calculation formula that must be satisfied between the item and other defined items. “Related item” indicates the item ID of the item that is referred to in order to calculate the value of the defined item. The definition may include values that the defined item can take.

The control unit 13 is, for example, a processor such as a CPU (Central Processing Unit). The control unit 13 functions as an acquisition unit 131 , an item identification unit 132 , a candidate identification unit 133 , an output unit 134 , and a position identification unit 135 by executing the program stored in the storage unit 12 .

The acquisition unit 131 acquires processing target data that includes a plurality of items. FIG. 4 is a diagram illustrating an example of processing target data acquired by the acquisition unit 131. The processing target data includes a plurality of items, and includes an item name and a value for each item. As an example, the acquisition unit 131 acquires processing target data from the information terminal 2. The acquisition unit 131 may acquire processing target data from an external device (not shown). Note that the acquisition unit 131 may acquire processing target data by acquiring image data of a document and performing OCR processing on the acquired image data.

The item specifying unit 132 specifies which of the defined items included in the format information each of the plurality of items corresponds to, based on the name of each of the plurality of items included in the processing target data. The item specifying unit 132 specifies items having names that match the names of each item included in the processing target data and the "item name" included in the format information, as defined items corresponding to the respective items. The item specifying unit 132 specifies, as unspecified items, items included in the processing target data that cannot be specified as defined items based on their names. As an example, in the processing target data shown in FIG. 4, since "total amount" does not match any of the defined items, it is specified as an unspecified item. Note that, as described later, the item specifying unit 132 may specify defined items corresponding to items included in the processing target data based on the meanings of the items included in the processing target data.

If there is an unspecified item that is an item for which the item specifying unit 132 cannot specify a corresponding defined item among the items included in the processing target data, the candidate specifying unit 133 specifies a candidate item for the unspecified item. As an example, the candidate specifying unit 133 specifies, for an unspecified item, a candidate item that is a defined item that is a candidate to which the unspecified item corresponds in the format information, based on the relationship between items included in the processing target data. That is, the candidate specifying unit 133 determines whether the relationship between the unspecified item and another item for which a corresponding defined item has been specified (hereinafter referred to as a specified item) is the "definition" of any defined item. Determine whether it matches the relationship indicated by . The candidate specifying unit 133 specifies a defined item whose relationship between the unspecified item and the specified item matches the relationship indicated by "definition" as a candidate item corresponding to the unspecified item. Further, the candidate specifying unit 133 may specify candidate items based on distances between items, as described later.

The output unit 134 outputs the unspecified item and the candidate item specified by the candidate specifying unit 133 in association with each other. The output unit 134 causes the information terminal 2 to display a screen for determining candidate items corresponding to the unspecified items. FIG. 5 is a diagram showing an example of a screen displayed by the output unit 134. In the screen shown in FIG. 5, unspecified items and candidate items specified by the candidate specifying unit 133 are displayed. When the user performs an operation on the information terminal 2 to associate an unspecified item with a candidate item (for example, when the button displayed as "OK" on the screen shown in FIG. 5 is pressed), the output unit 134 outputs the processing target Unspecified items in the data and identified candidate items are mapped. As an example, the output unit 134 generates processing target data by replacing the item name of an unspecified item in the processing target data with the item name of a specified candidate item. The output unit 134 may cause the storage unit 12 to store the generated data to be processed after replacement, or may output it to an external device that performs subsequent processing of the data to be processed.

Note that the candidate specifying unit 133 may specify a plurality of candidate items for one unspecified item. When the candidate specifying unit 133 specifies a plurality of candidate items, the output unit 134 may display a screen for selecting a defined item corresponding to the unspecified item from the plurality of specified candidate items. In this case, the output unit 134 generates processing target data in which the item name of the unspecified item in the processing target data is replaced with a candidate item selected by the user on the displayed screen.

Further, when the candidate specifying unit 133 cannot specify a candidate item corresponding to the unspecified item, the output unit 134 causes the information terminal 2 to display an alert warning that the candidate item corresponding to the unspecified item cannot be specified.

By configuring the information processing device 1 in this way, it is possible to reduce the effort required to process data to be processed, including items for which conversion profiles are not defined in advance.

The information processing device 1 may identify defined items corresponding to items included in the processing target data based on the meanings of the item names.

The item specifying unit 132 specifies defined items to which each of the plurality of items corresponds, based on the meaning indicated by each of the names of the plurality of items. As an example, the item specifying unit 132 uses known natural language processing technology to determine the names of items included in the processing target data, so that the item names have similar meanings to the respective item names of the items included in the processing target data. Identify the item. More specifically, the item specifying unit 132 calculates the degree of similarity between each item name of the items included in the processing target data and each defined item included in the format information, and if the degree of similarity is equal to or greater than a predetermined threshold. A certain defined item is identified as a defined item corresponding to an item included in the processing target data.

By configuring the information processing device 1 in this way, even if the names of the items do not completely match, the corresponding defined items can be specified. As a result, in the information processing device 1, it is difficult to map data to be processed, including items for which conversion profiles have not been defined in advance, with defined data, and it is possible to reduce the effort required to process data. can.

If a calculation method for a defined item is defined in the format information, the information processing device 1 may be configured to identify the item as a defined item corresponding to an unspecified item if the calculation method matches the calculation method. .

The acquisition unit 131 acquires processing target data that further includes an amount associated with at least one of the plurality of items. In the processing target data shown in Figure 4, "Subtotal" of "Product 1", "Subtotal" of "Product 2", "Total amount (excluding tax)", "Total amount (10% subject)", "Total amount" Amounts are associated in "(8% target)", "Total consumption tax amount", "Total consumption tax amount (10%)", "Total consumption tax amount (8%)", and "Total amount".

In the processing target data shown in FIG. 4, since the item "total amount" does not correspond to the item name included in the format information, as a result of the processing by the item specifying unit 132, the item "total amount" is an unspecified item. Identified as Then, the candidate specifying unit 133 specifies a candidate item corresponding to the unspecified item based on the result of calculating the amount. That is, the candidate specifying unit 133 determines whether an amount associated with an unspecified item is associated with one or more other items included in the processing target data, or an amount associated with a specific predefined item included in the format information. The related items are identified, and it is determined whether the results match the calculated results based on the calculation method for the related items. If the determined results match, the candidate specifying unit 133 specifies the defined item as a candidate item of the unspecified item.

Specifically, the candidate specifying unit 133 determines whether the “definition” of any predefined item whose format information includes the amount associated with the “total amount” item and other specified items is indicated. If the calculation formula is satisfied, the defined item is identified as a candidate item for the "total amount". Specifically, the related items for "Total billed amount" are "Total amount (excluding tax)" and "Total consumption tax amount", and the amount of "Total amount (excluding tax)" is "150,000 yen". Yes, and the amount of "total consumption tax" is "13,000 yen." Then, in the data to be processed, the amount of "Total Amount" is "163,000 yen", the amount of "Total Amount (excluding tax)" is "150,000 yen", and the amount of "Total Consumption Tax" is "13,000 yen". " satisfies the relationship with "total amount (excluding tax) + total consumption tax amount" in the "definition" associated with "total billed amount" in the format information, so the candidate specifying unit 133 Among the defined items, "total billed amount" is specified as a candidate item for "total amount", which is an unspecified item.

By configuring the information processing device 1 in this way, it is possible to map data to be processed including items that are not defined in advance to defined items.

By configuring the information processing device 1 to identify candidate items based on the position where an unspecified item is included, data may be mapped without having to define a conversion profile in advance.

The position specifying unit 135 specifies the position where each item included in the processing target data is arranged in the processing target data. The position where each item is placed in the processing target data may be, for example, the order of the items in the processing target data. Furthermore, in the case where the image data into which the data to be processed is input is obtained by OCR processing, the coordinates of the item may be arranged in the image data.

The candidate specifying unit 133 specifies a candidate item corresponding to the unspecified item based on the position where the unspecified item is placed in the processing target data. For example, if the data to be processed includes an item indicating a date, and the item specifying unit 132 cannot identify the corresponding defined item, the position where the date is included and the position where the "document number" is included are different. If the date is closer than a predetermined threshold, the "issue date" is specified as a candidate item for the date. Additionally, in a similar case, if the location containing the date and the location containing "remittance information" are closer than a predetermined threshold, "payment date" is identified as a candidate item for that date. .

The information processing device 1 may be configured to display a score indicating the likelihood of a candidate item.

The output unit 134 further outputs a score indicating the high probability that the unspecified item corresponds to the candidate item specified by the candidate specifying unit 133. That is, the candidate specifying unit 133 calculates the score for the candidate item. For example, the score is calculated based on the similarity between the item name of the unspecified item and the item name of the candidate item. The candidate specifying unit 133 may further calculate a score based on the positional relationship between the unspecified item and other items related to the candidate item. The output unit 134 may further display the score calculated for the candidate item on the screen displaying the candidate item.

By configuring the information processing device 1 in this way, the user can easily determine whether or not the specified candidate item corresponds to an unspecified item.

When a candidate item corresponding to an unspecified item cannot be specified, the information processing device 1 may be configured to display a name to be set for the unspecified item.

If the candidate specifying unit 133 cannot specify a candidate item corresponding to the unspecified item, the output unit 134 displays a name to be set for the unspecified item. As an example, in the storage unit 12, when processing target data and an item for which a name is to be set in the processing target data are input, a trained model that is trained to output a name to be set for the item is stored. The output unit 134 inputs the processing target data and the unspecified item into the learned model stored in the storage unit 12 and causes the information terminal 2 to display the output name. When the user operates the information terminal 2 to confirm the name, processing target data is generated in which the name of the unspecified item is replaced with the name output by the learned model.

By configuring the information processing device 1 in this way, it is possible to reduce the burden on the user in dealing with unspecified items.

[Flow of processing in information processing device 1]
FIG. 6 is a flowchart showing the flow of processing in the information processing device 1. The flowchart in FIG. 6 starts from the time when the data to be processed is acquired.

The acquisition unit 131 acquires processing target data (S01). The item identifying unit 132 identifies a corresponding defined item in the format information for each item included in the acquired processing target data (S02). The item specifying unit 132 specifies, as an unspecified item, an item included in the processing target data for which a corresponding defined item cannot be specified (S03).

The candidate specifying unit 133 specifies candidate items corresponding to the unspecified items (S04). The output unit 134 determines whether a candidate item corresponding to the unspecified item has been identified (S05). If a candidate item is identified (YES in S05), the output unit 134 outputs a screen for determining the defined item corresponding to the unspecified item to the information terminal 2 (S06). The output unit 134 outputs the candidate items identified by the candidate identifying unit 133 in association with each other on the screen displayed on the information terminal 2 . When the output unit 134 performs an operation to confirm a defined item corresponding to an unspecified item, the output unit 134 stores processing target data in which the name of the unspecified item is replaced with the name of a candidate item in the storage unit 12. Alternatively, the replaced data to be processed may be output to a device that executes subsequent processing. The information processing device 1 then ends the process.

If a candidate item is not specified (NO in S05), the output unit 134 outputs an alert indicating that the processing target data includes an item included in the format information and an item that cannot be mapped (S07). The information processing device 1 then ends the process.
