NLP, Text Categorization, Unstructured Data is a huge field.

I worked in a startup, whose competition was Autonomy's consumer internet spin-off in 2001

Text classification and analysis isn't a small field. Plus this is a public company that's been in the FTSE for years (i.e. one of the top 100 companies in the UK)

What’s your point?
