Spacy 2.0 fails to label plural proper nouns as NNPS

[anna-hope]

Sample input:

>>> doc = "Would this work with 5 iPhones?"
>>> doc[5].tag_ # expected NNPS
NNP

This occurs with every other proper noun I have tested. Spacy 1.9 correctly tags "iPhones" as NNPS.

Thanks for the report! Just tested it with the latest en_core_web_sm with the version currently on develop, and I'm getting NNS – still wrong, but this time in the other direction.

We're about to push some changes to the parser and are currently training new models, so once they're ready, I'll check again and see how they perform on your example.

Update: tried it with the new models and v2.0.0a18 and still getting NNS for your example.

However, for the latest version, we've also updated the training process and the examples, so you might be able to achieve pretty good results by updating the tagger with a few correct NNPS examples. See here for the example code: https://github.com/explosion/spaCy/blob/develop/examples/training/train_tagger.py

Merging this with #3052. We've now added a master thread for incorrect predictions and related reports – see the issue for more details.
