I thought there was a hint on the wiki once, that showed how to check if a tag is the only one. I cannot find that anymore. But anyway, I want to check if a word has more than one postag, no matter which those are, as long as those are not equal.
I think it is not possible to detect just “more than one POS tag”.
You can use <and> to detect that a token is a “noun” (or adjective, verb…) and something else:
I will have to make a large collection (>600) of separate rules to make it work then…
To improve the disambiguator, I need to know what it did so far, to be able to make additional rules.
Is there a different method to enhance the disambiguator systematically?
