Does anyone know about previous works on mapping ERG predicates to propbank and/or verbnet dataset?
In particular, I am curious about copula constructions. ERG gives me 2 analysis for
This balloon is red. and one analysis for
This is a red balloon. It seems we have two lexical entries for the verb be: be_c_is and be_id_is. So probably they may correspond to the two different senses be.01 and be.02 in http://verbs.colorado.edu/propbank/framesets-english-aliases/be.html.
Does it make sense?
