[Attribute Extraction Settings] Screen
This screen is displayed in the following cases.
- When [Add] is clicked on the [Form Type Setting] screen
- When [
] > [Edit] is clicked for an attribute on the [Form Type Setting] screen
It enables you to configure the method for extracting attributes from a form type.
To use AI extraction, select [AI Extraction]. To extract strings to the top, bottom, left and right of a keyword as attributes, select [Extract by Keyword]. To extract attributes from a specific area on the form, select [Extract by Area Specification].
The displayed screen depends on the item selected in [Extraction Method].
- [Extraction Method] cannot be set to [Extract by Area Specification] for a preset form.
- The settings of the items selected in [Extraction Method] are saved. The settings of the items that are not selected are discarded.
- There is a limit to the number of pages that AI extraction can be used with. You can increase the number of pages by purchasing an optional license.
- If the limit for the number of pages used is reached during job processing, the processing will continue even if the limit is exceeded. The number of pages exceeding the limit will be deducted from the total number of pages used after purchasing an additional license.
- If you run a job after the limit for the number of pages used is reached, the job will not result in an error, but the AI extraction results will be empty, so please enter the data manually.
- AI extraction uses generative AI, but the uploaded files and extraction results are not used for AI learning.
Also note that the extraction results may not be accurate. If necessary, check and correct the results on the [Data Validation] screen of the workspace.
- For information on data validation, see "Performing Data Validation on Documents".

Click [] to delete the entry field.
Specify a string that includes a keyword in [Keywords to Exclude].
When detecting attributes, the keyword to exclude (string A) and keyword to detect (string B) are searched for from the strings in the form. Areas where strings A and B overlap in the search results or form are excluded from the results due to string A.
| Keyword | Keyword to Exclude | Description | |
|---|---|---|---|
| Example 1 | sub | subsum | Because "subsum" includes "sum", it will normally be detected, but if "subsum" is included in the keywords to exclude, "subsum" will not be detected. |
| Example 2 | total | subtotal | Because "subtotal" includes "total", it will normally be detected, but if "subtotal" is included in the keywords to exclude, "subtotal" will not be detected. |
| Example 3 | total | tal | "tal" does not include "total". The "tal" keyword to exclude is ignored. |
| Example 4 | sub, grandtotal | subtotal | "subtotal" includes "sub" but does not include "grandtotal". In this case, values such as "sub", "grandtotal", and "subsum" (including "sub") are detected, but "subtotal" is not. |
| Example 5 | costsubtotal | costsubtotal | If the keyword is the same as the keyword to exclude, the search results are the same for both and no values with "costsubtotal" are detected. (The "costsubtotal" keyword is disabled due to the keyword to exclude.) |
- When determining whether a keyword is included in a keyword to exclude or searching for keywords and keywords to exclude from the strings on a form, the following are not distinguished.
- Spaces
- Hyphens, long-vowel symbols, or minus symbols
- Full-width and half-width characters
- Upper case and lower case characters
