Textract Queries returning false positive results

0

We are struggling with textract query results. The OCR is working correctly, as the text is pulling accurately but the queries are returning incorrect results. We are reviewing education documents and textract appears to say yes to most things. In the example below it is a "doctor of arts", when asked "Can you confirm if 'Maths' is present in the document?" the answer is returned as a high confidence yes.

For example: Accurate text: "Text": "has conferred on" "Text": "the degree of" "Text": "Doctor of Arts" "Text": "in Law And Legal Studies" "Text": "and all the rights and privileges thereunto appertaining." "Text": "In witness thereof, this degree duly signed has been" "Text": "issued and the Seal of the University affixed." "Text": "Presented on the twenty fifth day of" "Text": "April, two thousand and seventeen." "Text": "Pabe" "Text": "Jack" "Text": "lean"

Results: "BlockType": "QUERY", "Text": "Can you confirm if 'Maths' is present in the document?" "BlockType": "QUERY_RESULT", "Confidence": 87, "Text": "yes"

"BlockType": "QUERY", "Text": "Can you confirm if 'University of New York' is present in the document?" "BlockType": "QUERY_RESULT", "Confidence": 92, "Text": "yes"
