Hyphen not always being picked up by custom document processing model

Posted on by AVFC 147

Hello

 

I'm using a structured and have also used un-structured custom document processing model to capture table data from a pdf but as you can see below image it sometimes misses out the hyphen that i need in the amount column. Really can't see why it's doing this? There's no consistency to it..

    Hello,

     

    You are facing a known issue related to the OCR engine. Our team is working to improve that capability.

    As a workaround, you could make the logic conditional or use GPT data extraction method.

    This post should help you building that:

    Hope that helps,

    Hi Samia

     

    Thanks for the quick response and suggestions provided. This has now been resolved bizarrely by playing around with the settings in print preview on the original Excel file. The OCR is now picking up the hyphen after quite a few tests. It's just really weird that it was picking up the hyphen some of the time before but as you say your team is looking into improving the algorithm.

     

    Many Thanks
