Smart Fields Table Data

asked on November 25 Show version history

New to Smart Fields and testing various things. One interesting project is to pull line-item details from a table. In the tests I have run so far, the first line pretty much always returns correctly but the lower lines run into issues. Not OCR mis-read, but like data from one column being pulled into the field for a different column.

Has anybody run into this? Any ideas about a prompt or other change to do better on the lower lines? It's almost like ChatGPT runs out of steam after the first line and then doesn't work quite so hard.

We have made some enhancements to Smart Fields to improve dense table extraction for documents in similar formats that you have posted.  I was able to get good results with the following table with the latest updates.

 

Original Table: from "Hydro Extrusions.pdf"

Field Definition for Fe column:

 

With the table extraction enhancements which are released, please see if you are able to get better results.

Can you send us a sample doc? It might have to do with the quality of text extracted from images with that background.

Thanks, Miruna-

I'll attach 2 sample docs. The Hydro one is the one from the screenshot. Note that after the screenshot above I made a new template and tailored my prompts specifically for this 1 vendor, as opposed to 1 template for various different vendors, and it did do better but still missed that middle Cr value.

For context, there is a separate large, expensive AI project underway to extract these chemical values--along with other things--and automatically upload the values into an ERP system. I'm hoping that we can do it with Laserfiche because it would be much faster and cheaper. But it has to be super accurate.

And yes, these images were scanned from paper, and I expect to need to be able to process that way. We do receive PDF copies ahead of shipments but they aren't always accurate. Like, the specific piece of metal might get changed for the shipment, which would mean the heat number and chemical analysis would be different.

EDIT: I keep getting a server error when trying to attach PDF files (73 and 262 KB). As did pasting a screenshot of the error message.

Looks like upload is working again. Here are the files.
