Different %mor lines for same transcript

[Brielle Stark]

Hi all, 

I've attached two identical transcripts, one done with a slightly older clan version and one done with the most recent clan version. Mor was run identically on both. The participant tiers are the same but I notice the mor tier is different in the &uh looks .. line, the penultimate line in the transcript. Since one is tagged as a cop and the other a verb, the two transcripts, albeit identical, present with different propositional density scores. This isn't a problem, just trying to sort out the reason! 

Thank you!

Dear Brie,

    The verb "looks" is ambiguous between v|look-3S and cop|look-3S.  In this case, the current version of MOR made the wrong choice.  However, we now have added a facility to MOR that uses the prepost.cut file to make a better choice.  The relevant rule chooses the verb listing before a preposition.  So, the most current version of MOR will get this right.

     More generally, tagging for part of speech in English will always make a few errors.  Our goal is to continually reduce the error rate and the prepost.cut facility helps in that regard.
