I was just writing a fairly novice piece about how to find names in text. 'rules' I have are: following a title, capitalised, capitalised word (x2) followed by a comma and an integer (eg. John Doe, 27) and the one I can't explain properly, followed by verbs which are usually applied to humans such as said, reported, claimed, thought, argued, bought.
I just assumed that those verbs would have a category of their own
