Multi-modal document type classification systems and methods

A method of using an artificial intelligence (AI) system to classify documents, the method comprising the steps of:

• receiving, at a platform server running the AI system, a file comprising a document;
• visually identifying that a barcode is present on the document;
• decoding the barcode to extract barcode data;
• and
• using the barcode data, detecting a document type, wherein detecting the document type comprises determining whether the barcode data is in a valid format corresponding to an expected format for the document type;
• and
• verifying the document based at least in part on determining that the barcode data is in the valid format.

A method of using an artificial intelligence (AI) system to classify documents, the method comprising the steps of:

• receiving, at a platform server running the AI system, a file comprising a document;
• detecting whether a barcode is present in the document;
• upon detecting a barcode on the document, decoding the barcode to extract barcode data;
• conducting optical character recognition (OCR) on the document to extract text content;
• detecting a visual feature present on the document;
• detecting a document shape;
• detecting a shape of the document;
• identifying a document candidate based on at least one of (a) the text content and (b) the visual feature, wherein the document candidate has an expected document shape;
• determining that the shape of the document matches the expected document shape;
• and
• classifying the document with verification that classification is correct.
