Hello, The header files are also included in the official repo (for Spanish and English):
https://github.com/apache/opennlp/tree/master/opennlp-tools/lang/en/parser https://github.com/apache/opennlp/tree/master/opennlp-tools/lang/es/parser The format and content of the header rules comes from Collins thesis, Appendix A: http://www.cs.columbia.edu/~mcollins/papers/thesis.ps On Tue, 21 Jul 2020 at 14:24, Markus Jelsma <markus.jel...@openindex.io> wrote: > > Also, our source data does not use UD or Penn-treebank type POS-tags.

The head rules files try to find the head for every type of constituent except for Noun Phrases, which directly included in the head rules parser class, here: https://github.com/apache/opennlp/blob/master/opennlp-tools/src/main/java/opennlp/tools/parser/lang/en/HeadRules.java https://github.com/apache/opennlp/blob/master/opennlp-tools/src/main/java/opennlp/tools/parser/lang/es/AncoraSpanishHeadRules.java Thus, if you do not use Penn Treebank tags or constituents then you can include all the rules with the tags you use in the head rules files directly.
