Use Machine Learning to Extract Information from Documents

Document Information Extraction uses a globally pre-trained machine learning model that currently obtains better accuracy results with invoices and payment advices in the languages listed in Supported Languages and Countries. The team is working to support additional document types and languages in the near future.

Upload to the service any document file in PDF or single-page PNG and JPEG format that has content in headers and tables, such as an invoice.

As an alternative to uploading your own documents to the service, you can use the following sample invoice files (right click on the link, then click Save link as to download the files locally):

• Sample Invoice 1

• Sample Invoice 2

• Sample Invoice 3

1. Open the Document Information Extraction Trial UI, as described in the previous tutorial: Subscribe to Document Information Extraction Trial UI.

   

2. In the top right, click + (Upload a new document).

   

3. In the Select Document screen, drop files directly or click + to upload one or more document files.

   

4. Select the Document Type. Click Step 2.

   

5. In Step 2, select the header fields you want to extract from the documents you uploaded in the previous step. Click Step 3.

   

6. In Step 3, select the line items you want to extract from the documents you uploaded in the previous step. Click Review.

   

7. Review your selection. Click Edit if you want to change anything. Click Confirm.

   

   You see the Document Name, Upload Date and Status of the documents you have just uploaded.

   

   Status changes from PENDING to READY. This means the selected header fields and line items have been extracted, and the extraction results are ready to be validated and changed if necessary. If status changes from PENDING to FAILED, this means it was not possible to get the extraction results, and you need to upload the document once again.

   

CAUTION:

Be aware of the following Document Information Extraction Trial UI trial account limitation:​

• Maximum 40 uploaded document pages per week​ (the documents can have more than 1 page)​

1. In the Documents screen, click the document row where you see Document Name, Upload Date and Status.

   

   You see the page preview of the document file you uploaded.

   

2. Click Extraction Results to see the Header Fields and Line Items extraction results.

   

3. In case corrections are needed and the document status is READY, you can Edit the Header Fields and Line Items extraction results.

   

   See an example where the Currency Code is edited:

   

4. You can also Add Line Item and Delete Last Line Item.

   

5. Select values in the document page preview, one each time, to Assign Field by choosing in the dropdown list the Field name. Add or change the extraction Value if necessary. Click Apply to add the selected field into the Header Fields or Line Items extraction results.

   See an example where the Tax Amount value is selected in the document page preview and added to the Header Fields extraction results:

   

6. Save your changes.

   

7. You can also Edit and Confirm the document.

   

   Status changes from READY to CONFIRMED. This means the extraction results have been confirmed and can no longer be changed.

   

1. In the Documents screen, click the document row where you see Document Name, Upload Date and Status.

   

   You see the page preview of the document file you uploaded.

   

2. Click Delete and then click OK to delete the document you selected.

   

   The document is then removed from the Documents list.
