Guide on Training assertion module

Hi

Is there a guide on how to train the assertion module to get the correct
polarity etc.
I have some good data to train.
Currently simple negation is not recognized.

Thanks
Harish

Hi Harish,
The module has code for training from i2b2 challenge-style annotations
and SHARP annotations (knowtator xml). If you have one of those datasets
or a similar representation you can find the training code in the
assertion module. If you have some other form you may be able to look at
the data readers for those formats and write your own reader for your
own format. You may also be interested in reverting to the rule-based
negation annotator -- it has lower precision but higher recall.
