Hi Rocco,
Thanks for your interest and for suggesting improvements. You are right,
co-reference resolution was not a focus of this first release. At this point
we only do some simple rule-based propagation of references. It is within
our interests for future work, however, to use machine learning to improve
our co-reference resolution. If you are interested in contributing towards
that, please feel free to contact us.

At this stage we focused more on the flexibility, in order to allow people
to reuse the software in many use cases. If you want to reduce the risk of
getting many mismatches, you can always configure the confidence parameter
to a higher value. I can see, for example, that with confidence 0.6 we only
see one error for the text you provided.

See:

Best regards,
Pablo Mendes
