At first glance, you can probably solve the easy problems with the solutions you have today, assuming you’ve kept up with newer versions of your capture software. Your biggest opportunity in the next couple years will likely be to focus on the Moderate problems and some of the Difficult problems. After that, you can consider tackling the more complex, Difficult tasks once you have that set in happy production.
For example, if you can do a good job at Document Classification, you don’t have to do much document preparation. These new tools can automate - or near automate - this task better than previous tools. Once you tackle that, in a few years, you can take on package classification. This is where you identify a whole set of documents and prepare extraction and validation for what to expect.
In terms of extraction, you can increase accuracy on machine text well beyond 99%. You can also address handprint and handwriting, first in structured English and then later in unstructured other languages (e.g., Spanish).
For validation, you can check for completeness and correctness in entire documents – what’s called NIGO (Not in Good Order) processing.
Later on, you can do NIGO processing for entire packages of documents such as in a loan application. Or, check not just signature presence, but correctness.
