Extracting “other” information from Azure Form Recognizer’s Prebuilt Invoice Recognize output

Question

Hi all,
I did a comparison between Amazon Textract and Azure Form Recognizer. Azure Form Recognizer gives key value pairs as output and it contains these fields. This covers quite a bunch of fields. However Textract only covers very few fields (see here)

Now even though, Textract doesn’t identify many fields in a standard manner but it still recognizes key value pairs from the document well. For instance, if a document has a field P.O. # 1234567, Form Recognizer misses it but Textract extracts it and labels it as “other” fields.

I want to stick with Form Recognizer because the overall accuracy is better and it recognizes more fields which are missed by textract if they are not explicitly mentioned.
But the way Form Recognizer gives the output, I can’t find a way to extract those “other” fields other than having to parse the JSON and creating some rules. I was wondering that maybe I am missing something here and maybe Azure does provide some way to access these values directly similar to Textract.

Please let me know if I need to add any more info here. TIA.

Answer 1

Hi, we are planning to add a new API into Form Recognizer to detect generic key/value from any document which will be released very soon. This API should help to detect fields which are not detected or not defined by Invoice API. You will need to make two API calls (invoice and the new api), but this may change in a future.
