Thank you Emily, I found one mention in https://plato.stanford.edu/entries/situations-semantics/. But in the context of the Lisp code, I am curious why the authors used this in the suffix of the function name…
BTW, I reported two issues on pydelphin and ERG repositories:
https://github.com/delph-in/erg/issues/25
The trunk version of ERG gave me this MRS..
[ TOP: h0

Handle h23 does not appear in the predicates. The h5 and h8 only in the arguments. Is it valid?
Pydelphin transformation to DMRS works with a warning "broken handle constraint”. Can it be transformed to EDS? Is this an evidence that MRS to EDS is much less robust than MRS to DMRS?
BTW, since I am having so many trouble with MRS to EDS, and my goal is to compare a golden version of a profile with its 1-best parsed version to evaluate the parse selection model, I wonder if I could be doing that with DMRS instead of EDS… any idea? Any alternative to https://github.com/delph-in/delphin.edm using DMRS?
Best,
Alexandre
