The use of AI in intelligent document reading, classification, data-extraction, workflow, verification and approval is really coming together. At the moment there are a good selection of tools/services that do some of this but there are emerging some serious players in the development of rounded, cross-platform single-point-of-fact systems. I work at the junction of document management and intelligent document processing specialising in Accounts Payable - it's a very exciting time to be in this sector.
