In all honesty the technology is good but it's only part of the way to where you need to be. It does half a job fairly well. Despite what the software sales people may tell you!
Over 20 years we have tried, and continue to experiment with every product on the market and they are much the same.
Ai and machine learning are making huge strides and we don't doubt that eventually this task will be within their remit. However at the moment its only really useful for areas that simple rules can be applied to.
Software solutions struggle with the context and understanding of text within the document. Assigning ownership of content to a subject (vital with a Subject Access Request) still needs human input to examine the context and make an informed judgement based on experience and understanding.
Yes we use Ai and machine learning to minimise price but all our projects receive x3 run throughs by x3 different humans to guarantee quality. In our view its essential. We can give you countless examples of where a data breach would occur by relying on software alone.
