Two root nodes from one sentence to the DP, any advice? about nlp4j-old

I've been able to demonstrate this using your stock English model.

As well as for complex voice emotional recognition for emotions not included in Mind Reading .

I tried adding a feature to the model.

Please don't laugh if my attempt to figure out the feature templates was unsuccessful.

My idea was to discourage things like a conj deprel with the root. Of course, this sort of thing can't globally ding sentences for having more than one root. If there's a way to introduce that idea into the feature set I haven't understood it yet.

   <feature f0="i:dependency_label" f1="i_h:part_of_speech_tag"/>

With my universal training (UD treebank + converted PTB) and the UD dev set the accuracy was the same,

UAS 0.88 LAS 0.85 total tokens 25148

but the number of two-headed outputs from the UD dev set dropped from 4% to 3%.

We somewhat belatedly read the papers and understand that this is expected, so we thinking about how to cope.

Sorry for the late reply; I was meeting a grant proposal deadline. Multiple roots may be caused because by headless nodes; when the parser doesn't find any head, then it by default connects it to the root to keep the entire tree connected, but this is something I should retouch. I'm planning to adapt our structure to UD more now, so I can experiment this more myself as well.

OK, thanks.
