Advise on Dependency Training for Improving Sentence Breaking

Hi All,

I'm looking to label chat message dependencies and want to improve the spacy parser sentence breaks. I currently use a combination of my own sentence breaks & overrides of the parser. I'm hoping to improve the parser at this point to better separate phrases in a message, but I haven't been able to find an example or find any guidance on how to proceed.


  1. how does the dependency parser decide when to break a sentence?
  2. what considerations should I make if I build a custom dependency parser to get sentence breaks working?
