Parse out phrasal verbs
stanford-nlp
Solution
Dependency parsing, dude. Look at the prt (phrasal verb particle) dependency in both sentences. See the Stanford typed dependencies manual for more info.
nsubj(climbed-2, We-1)
root(ROOT-0, climbed-2)
det(hill-4, that-3)
dobj(climbed-2, hill-4)
prt(climbed-2, up-5)
nsubj(have-2, I-1)
root(ROOT-0, have-2)
aux(do-4, to-3)
xcomp(have-2, do-4)
det(job-6, this-5)
dobj(do-4, job-6)
prt(do-4, over-7)
The stanford parser gives you very nice dependency parses. I have code for programmatically accessing these if you need it: https://gist.github.com/2562754
Problem
Has anyone ever tried parsing out phrasal verbs with Stanford NLP? The problem is with separable phrasal verbs, e.g.: climb up, do over: We climbed that hill up. I have to do this job over. The first phrase looks like this in the parse tree: ``` (VP (VBD climbed) (ADVP (IN that) (NP (NN hill) ) ) (ADVP (RB up) ) ) ``` the second phrase: ``` (VB do) (NP (DT this) (NN job) ) (PP (IN over) ) ``` So it seems like reading the parse tree would be the right way, but how to know that verb is going to be phrasal?
