I think it would be great if OpenNLP could provide feature extractors and pre-trained models to perform Semantic Role Labeling for relation extraction (maybe for a restricted list of predicates). But this probably a non trivial task and it is only interesting if we can get a good F1 score (or at least precision) for this task. -- Olivier http://twitter.com/ogrisel - http://github.com/ogrisel
