grammar analysis software

Hi everybody!

Could you suggest me a grammar analysis software ?
I'm searching for a software in which, given a generic word, it gives me the grammatical value.

For example:
who -> interrogative pronoun
and -> conjunction
...

Thanks!

However, grammatical analysis is in its infancy and there are major problems with words that fall into a number of grammatical categories, so don't assume that it is always right.
