<div dir="ltr"><div>Hi,</div><div><br></div>To expand on Ann's email, the problem I needed to solve was to align the DMRS EPs with PTB-style tokenized sentence. In addition to punctuation and whitespace differences, I needed to align null semantics items that are not associated with any predicate in the ERG. The latter is done using heuristics.

The initial tokens ('p-input' in the 'parse' table of a [incr tsdb()] profile) can tell me the span of individual tokens in the original string, which I could use to compute the adjusted spans. This seems simple enough, but then it gets complicated as there are separated tokens that should still count as a single range (e.g. "could n't", where '_can_v_modal' and 'neg' both select the full span of "could n't") and also those I want separated, like punctuation (but not all punctuation, like ' in "The kids' toys are in the closet.").<br> ><br> > Has anyone else thought about this problem and can share some solutions?
