How to train and create Coreference models

[Carlos Scheidecker <na...@gmail.com>]

Jörn et all,

Allow me to abuse a little further. How do I go to train Coreference
models? Any hints on the code for achieving that and creating the files?

Also, is the format for NERs on 1.5x different than the one on 1.4x and
under? Seems to me that the coreference models are different.

Is it because the NERs code has been updated and the Coreference still not?

Thanks again,

Carlos.

First part of my answer. Yes we updated all the components expect the
coreferencer to use a model package, this package includes everything that
is needed to run a component from a model. No further configuration is 
needed.
Evaluation support is also on our wish list.

You can use the 1.5 NER models, but the coreferencer models are the same for
the 1.5 release as they have been for 1.4.

The coref component was always a bit special because we do not really have
data to train it. I got a copy of MUC 6 / 7 data and added formats 
support for that
to it, but there are still some minor issues. It would be nice to get 
that fixed!

Answer about how the training is supposed to work will follow.
