Question 6

[andrefurlan]

Use WordNet and ProNTo_Morph to dramatically expand your program's
vocabulary. You should use ProNTo_Morph to stem words and then find the stems in
WordNet. WordNet's s/6 predicate will tell you what part of speech the word is
(although note that a word may belong to multiple parts of speech!). You should add
rules to the grammar that incorporate these new words. Ensure that backtracking
across the different parts of speech in WordNet and the different possible
stemmings in ProNTo_Morph works correctly!
Your code should now be able to handle sentences like "it is an amusing hyena"
without explicitly adding those terms.
Notes: You should consider WordNet's "satellite" adjectives as normal adjectives.
Also, you may want to check whether the unstemmed word is in WordNet before
trying stemming to avoid, e.g., turning adverbs into adjectives. Finally, it's up to you
what to do with plural forms (e.g., should "eats" match "eat"), but decide what
you're going to do and justify your decision!
