Table extraction from PDF where row data is long

Posted on by rahullakshmanan

Hi,

We have a Editable PDF which has a static table with fixed width, rows and columns. We only need to capture the material description. The model works well in cases when the material description is short and fits in a single line.

When the description is long it wraps in the same row in two lines. The AI builder recognizes this as two rows instead of one.

I have a ticket open with Microsoft (TrackingID#2109290060003230)and it states that this is a known bug and is being worked upon.

Anyone else face the issue?

Hi @rahullakshmanan,

Thanks for your question.

How many documents did you use for training? The more samples you can provide for training where the 'material description' is long, the better the model will get to learn how to recognize rows.

Hi again!

I've tested the documents, and the table extraction results seem correct. 🙂 I've sent you a private message to share how I've done the tagging, and keep investigating as we discuss the specifics of your documents.
