Link grammar has a website and online demo at http://www.link.cs.cmu.edu/link/submit-sentence-4.html But as I posted earlier, it gives the same parse for: - I ate pizza with pepperoni. - I ate pizza with a friend. - I ate pizza with a fork. which shows that you can't separate syntax and semantics. Many grammars have this problem.
Link grammar (similarily to CFG and most other approaches that don't already do it) can be extended with feature structures to be unified online in the run of the parser (leading to so called unification grammars). Nothing stops you from putting semantical information into these structures as long as it is monotonic. (Of course you cannot machine-learn these structures out of pure air.) ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=231415&user_secret=e9e40a7e
