Hi Andreas, This issue has already been discussed here, so I will summarize:
the english head rules come from Michael Collins thesis, check Annex A http://www.dfki.de/~neumann/dop-seminar/References/collins-thesis.pdf I have recently posted about the head rules in Spanish (Ancora corpus) https://issues.apache.org/jira/browse/OPENNLP-665 Also check the 7th of March thread about language specific headrules when training parser Finally, Stanford Parser provides headrules for the Negra corpus, which could be useful for you. corenlp/edu/stanford/nlp/trees/international/negra Cheers, Rodrigo On 2014/03/19 at 15:02, Andreas Niekler wrote: > Hi all, > > i want to train a german parser model with the tiger corpus.
