Hello everybody, how can we understand what are the most important features during the NER process? I mean.. when the TokenNameFinder selects a label is it possible to retrieve the most important features too ? Thanks Damiano

Hello everybody, i am dealing with data normalization on very bad sentences with many spelling errors. Do you know a good paper to understand how to build a model that will fix this kind of problem? I can share the code without problems if you are interested in integrating it into OpenNLP.
