Use AllenNLP Semantic Role Labeling (http://allennlp.org/) with SpaCy 2.0 (http://spacy.io) components and extensions

spacy_srl.py

# This small script shows how to use AllenNLP Semantic Role Labeling (http://allennlp.org/) with SpaCy 2.0 (http://spacy.io) components and extensions
# Script installs allennlp default model
# Important: Install allennlp form source and replace the spacy requirement with spacy-nightly in the requirements.txt
# Developed for SpaCy 2.0.0a18

@felgaet I've used this previously for converting docs to conll - https://github.com/BramVanroy/spacy_conll
I don't know if this is exactly what you are looking for but might be a starting point to where you want to get.
