<div dir="ltr"><div>Hi developers (but mostly Stephan and Dan),</div><div><br></div><div>I'm turning my attention briefly from TDL to making the MRS -> EDS conversion in PyDelphin more harmonious with the LKB, and the first order of business is implementing "predicate modification".</div><div><br></div><div> I'd like to only use grammar-agnostic graph properties to find the "representative nodes" of EP conjunctions, as I do with MRS -> DMRS conversion, but the LKB currently does a regex match on the predicates of EPs in a conjunction, something like "if the predicate matches /_x_deg$|^neg$|^_quite_x$/ and it's ARG1 is not currently assigned, set its ARG1 to point to another EP in the conjunction, with some other heuristics at work to select that other EP. (Aside: I think this ERG-specific regex pattern is now grammar-defined instead of being baked into the LKB, but currently I only see lkb/eds.lsp in the LOGON version of the ERG---not the trunk version) The _x_deg$ subpattern handles, e.g., "nearly all", "not all", etc., but I was having trouble finding a construction where the neg$ subpattern selected a predicate modifier (any ideas?).</div><div><br></div><div>My main concern, however, is with the _quite_x$ subpattern. It seems to work well enough with "quite a few dogs bark." and "quite many dogs bark." (and also "quite all dogs bark" and "quite dogs bark", but my grammaticality judgments differ with the ERG's here). "Not quite all dogs bark" uses _not+quite_x, which doesn't match any subpattern and thus is disconnected in EDS. The strangest one is "quite nearly all dogs barked", where in the EDS _quite_x and _nearly_x_deg select each other, cyclically, as their ARG1s (the MRS for this is as one would expect).</div><div><br></div><div>My guess is that the *eds-predicate-modifiers* pattern is out of sync and/or insufficient with the current ERG. There are bigger issues here, such as our ever-unsatisfying treatment of quantifier modification, but right now I'm just trying to figure out a good way to do EDS conversion.</div><div><br></div><div>A request, though: if we're not going to allow quantifiers to be selected as the ARG1 of degree modifiers in MRS, can we use a different role (e.g., MOD) in EDS? That would make back-conversion simpler, I think.</div><div><br>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Michael Wayne Goodman</div></div></div></div></div></div> </div></div>
