If, instead of resolving that ARG0 to the "leaving", which Dan and I agree would be inappropriate for some potentially intended semantics, there was a form of co-reference other than (in)equality, such as the "same type" I suggested below, I guess you would not need the additional argument for "so/it"! Until now, I had no need to introduce additional predicates into the semantics, but to do so seems appropriate after the discussion , so thanks again for your patient coaching, Dan and Emily. Actually, any references on representing the forms of reference as additional predicates in less underspecified logical semantics would be sincerely appreciated. For example, the classic "the men lifted the crates" or "substances cross the plasma membrane at different rates". I still think an issue lurks here, however, as shown in the following examples. <img src="cid:part1.05090103.04000505@haleyai.com" alt=""> <img src="cid:part2.04000509.01060604@haleyai.com" alt=""> Paul<div><div class="h5"> On 10/24/2013 7:31 PM, Emily M.

No problem agreeing with the first clause of your second sentence, but I don't think the second clause involves coercion as much as proper logical semantic structure. I'm not suggesting anything more than a semantic argument is missing. I'm not expecting sentence-oriented processing to do anything at all in terms of anaphora resolution. That's how it works now (i.e., without a resolution mechanism, which is just fine, imo), but the variable/argument seems critical in any case. I don't see how to approach it otherwise. Inter- vs. intra-sentential resolution doesn't seem pertinent here. I didn't know we had ICONSs! Sounds interesting... and potentially combinatoric. Should be fun. I'm not sure additional types of constraints for verbal anaphora are needed (i.e., we've lived long enough without ICONSs) but if there is a linguistic distinction between such reference to an instance versus a type of event, that would be appropriate too. Without them, the semantics is just more underspecified, which is fine as long as it covers the intended meaning. It seems clear that the representation we have now does not in the cases at issue here. <div> <div> On 10/22/2013 1:57 PM, Dan Flickinger wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi Paul - I agree that we don't want to identify the two events as the only possible interpretation. But we have to allow anaphora resolution to perform its magic quite generally, and it is I think misguided to try to coerce the sentence-level semantic composition to do too much. If the text to be parsed were two separate sentences, I hope you would agree that our sentence-oriented processing could not be expected to constrain the elided event via unification: "Kim bought a car. Mary did so, too." So we have to be content in the grammar to set the stage for a currently unimplemented resolution engine separate from the current grammar that will bind these anaphoric elements both sentence-internally and across discourse. This underspecification is very much the same as the approach we take to ordinary pronoun binding, though we do expect to enrich the grammar's MRSs for sentence with pronouns a little more, now that we have a place to assert structurally derived constraints on equality and inequality of individuals, as ICONSs. But I don't know of analogous structural constraints (such as c-command) for verbal anaphora, and in any case these would again be only sentence-internal.

They may have left together or at different times or independently at the same time. In theory, all of these logical/semantic interpretations should be consistent with the resulting underspecified semantics. The MRS below corresponds, roughly to: exists(e10,e14,x6,x17){leave(e10,x6),named(x6,Kim),do_so(e14,x17),named(x17,Sandy)} If e14 co-references e10, this implies there is one leaving event "performed by" both Kim and Sandy, which may or may not be the appropriate logical interpretation. If not, how is e14 to understood as a leaving? One resolution of this would be to have an argument, such as follows: exists(e10,e14,x6,x17){leave(e10,x6),named(x6,Kim),do(e14,e10,x17),named(x17,Sandy)} This representation would allow either semantics to result from further (logical) disambiguation. I submit that the MRS resulting now is insufficient to represent the underspecified semantics. Alternatively, I suppose, one could introduce an underspecified form of co-reference in which e14 references e10 other than as logically equivalent, but that raises issues not previously addressed (in any literature that I have seen) with regard to the relationship between underspecified representation and logical axioms.

The point of my examples was that that event might have any number of participants, and so looking for an ARG2 specifically seems misguided.

That's the problem. The semantics is wrong. Worse, "it" is frequently interchangeable with "so" in such constructions, as shown below (as in the case of my first example further below). The pronoun refers to the event, of course. That reference is missing in the semantics for "so". Seems to me that "so" in this construction is an 'e' pronoun (where "it" is a 'x' pronoun below, which could also be a bug, imo.) On 10/10/2013 7:28 PM, Emily M.

Yes, but I'm suggest that "pro-" is "pronomial" not "proto"!-) Generally, don't we want elipsis to be reflected in the semantics? That is, in the "u" and "i" type variables in the MRS (or unresolved pronouns)? Shouldn't the MRS for for that doing have an argument to be resolved against the situational argument for the moving? That argument would be "so" treated as a pronoun, which seems the proper semantics since the "so" actually/semantically references some event/situation, no? That is, if pronomial "so" was the direct object of "do" here, I think all would be well. Paul On 10/8/2013 9:14 PM, Emily M.
