Some part of the text is not recognizing in the API version 2024-11-30 while using Azure Document Intelligence Custom Extraction Model

Rajesh Sreenivasan 10

I am using Azure Document Intelligence and Custom extraction model. I have trained a couple models and when I try with a pdf document and "Run Analysis", It wont read some part of the text. I am using an API version 2024-11-30. But its working perfectly in the API version 2024-07-31.

Is there any way to solve this problem?

API Version 2024-07-31

API Version 2024-11-30

Hi Rajesh Sreenivasan,
The issue seems to be that the newer API version (2024-11-30) of Azure Document Intelligence is failing to recognize some part of the text, while the older API version (2024-07-31) works perfectly.

To resolve this, you can try retraining your custom model using the 2024-11-30 API version to ensure it's compatible with the latest text recognition updates, and include a diverse range of document samples with similar formatting.
Next, carefully review and explicitly set analysis parameters like splitMode in your API request, as these settings influence document processing and might help maintain behavior consistent with the older API version. Finally, test your document with Azure's prebuilt models, such as the Layout or Read models, using the 2024-11-30 API, to determine if the issue is specific to your custom model or a more widespread problem with text recognition in the newer API version.

I hope this information helps.

Hi @Pavakumar Purilla

Thanks for your response. But as you suggested, We cannot user the previous API version (2024-07-31). Since latest API (2014-11-30) we have used in our applications. So its difficult to revert to old api version.
