<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">This is puzzling. There are no errors in the training corpus and one would think that POST could learn the context needed to disambiguate these. It is true that clitics are one of the
most difficult things for learners, but a program should be able to figure this out. Fortunately, it should be possible to fix these using POSTMORTEM. I will work on the rules for that. However, the other better approach would be to generate more training
files for Spanish. That has been a problem. I was hoping for some volunteers, but none have emerged so far. It is not that hard a job, but it would take a few days to make sure all the training materials were correct.<o:p></o:p></span></p>

<p class="MsoNormal">In using the Spanish tagger, I have come across the following consistent error: determiners (la, los, las) are consistently mislabeled as their homophonous clitics. See the following example from the most recent version of Orea-Pine corpus.

<p class="MsoNormal">While MOR correctly provides both labels, POST often chooses the wrong label. I see many cases of determiners mislabeled as clitics, but not the reverse.<o:p></o:p></p>
