I was thinking about something along exactly these lines, so we may just be two talking @$$'$

What'd be interesting is trying to look for "contextual words", so does May refer to the month or the daughter, London is a place, or Jack London. It would be impossible to predict all of these ambiguities, so the "training" makes a lot of sense to me.

Of course, you will never achieve 100% accuracy but I don't think you want to.

Absolutely correct - we don't depend on this data, it just adds value when we can extract it.

thanks for the input
