Answer 1

Yes, you need your own training set. The pre-trained Stanford models only recognise the word "Stanford" as a named entity because they have been trained on data that had that word (or very similar words according to the feature set they use, I don't know what that is) marked as a named entity.

Once you have more data, you need to put it in the right format described in this question and the Stanford tutorial.
