Changing this to use `prefer_uncertain` isn’t too hard, but also isn’t entirely trivial. The issue is that spaCy’s `nlp` object doesn’t return scores for the entities by default, as the model actually doesn’t produce any scores that can really be interpreted that way (it’s a transition-based model).

See this issue for an explanation of how to use a slightly different model in spaCy to get entity probabilities: [Accessing probabilities in NER](https://support.prodi.gy/t/accessing-probabilities-in-ner/94/2)

Once you have the scores, you can change your stream to produce `(score, example)` tuples, and then wrap the scored stream with `prefer_uncertain`.
