How to read multiple pages table data using Azure AI | Document Intelligence Studio | Custom Extraction model

Sanjay K 5

Hi Team,

I am doing one POC to read the pdf document contains Text and tables data and facing the problem to read the table data (if same table data extended to multiple pages) from multiple pages.

Request to let me know if any suggestions on the same.

Thanks.

Hi @Sanjay K ,

Thanks for sharing the details. To read the table data from multiple pages, the custom template models will add support for cross page tabular tables:

To label a table that spans multiple pages, label each row of the table across the different pages in a single table.

As a best practice, ensure that your dataset contains a few samples of the expected variations. For example, include samples where the entire table is on a single page and where tables span two or more pages if you expect to see those variations in documents.

Please refer to the document. I hope this information helps. Thank you.

Hi Team,

I have tried with custom extraction model but no luck and correct me if i am doing any mistake in the set up.
My requirement is : I will receive a table format in a pdf and for few pdf's table rows extend to multiple pages (each page have seperate table header) and for few pdf's table data may come in a single page only.

When i am label the data in page 1 and page 2 then any one page table data assigned for label.

Please assist on this and if required we will do a screen sharing session.

Hi @Sanjay K ,

Thank you for providing more details about your query.

Based on your description, it seems that you are having trouble labeling table data that spans multiple pages, and only one page's table data is being assigned for labeling.

To help you with this, please look into the below file:

DocIntel_Table.gif

I hope this information helps! Please do check and let us know.

Hi Santoshkc,

I have checked above suggested flow but it is giving result as First page first row and next page first row only. But i need First Page and Second page entire table data. Request to Provide a clarification on this ASAP.

Hi @Sanjay K ,

Sorry for the trouble you are facing. I tried from my end by uploading the document for your use case (table was splited to multiple pages) and the Model is capturing or predicting the entire table from all the pages. For your reference, please look into the below.

I hope you understand. Thank you.

Hi @Sanjay K ,

Regarding the labelling, already I posted the demo in the previous comments. See here: DocIntel_Table.gif

Regarding Model setup: After model training, just click on the Test tab, upload your document and click on Run analysis.

I hope this information helps.

I have followed the video you posted and have mapped a few rows from each page of the table which spans multiple pages. When the training is complete and i test, the data returned is only from the rows which i mapped.

See below:

The Test return perfectly read the 7 mapped fields but not all in the table.

I mapped the headers in the manual table like the video and highlighted and inserted the sample data.

Please can you let me know how i can get the full table from all pages, sometimes 8 pages where i specify the headers? Do i need to map a version of the pdf with 8 pages? what if there is nine.

Everything is very clear and successful other than this point of getting data from multiple pages.

Thank you Support.

Has there been any progess in this matter?

I'm having the same issue. Some Rows in my table span over 2 Pages. So even though different entries are recognized if a row spans over two pages, the information from the second Page gets lost.

Page 1

Header 1 Header 2

Row 1 Row 1 - Text

Row 2 Row 2 - long text

Page 2

Header 1 Header 2

Row 2 - more text

Row 3 Row 3

In the example above I'd get the entire data from Row 1 and Row 3. But only the begining of Row 2 (long text) which is above the horizontal line and not the part from the second page ( more - text)

Is there any known workaround?
