| spaCy takes training data in JSON format. The built-in
| #[+api("cli#convert") #[code convert]] command helps you convert the
| #[code .conllu] format used by the
| #[+a("https://github.com/UniversalDependencies") Universal Dependencies corpora]
| to spaCy's training format.
+aside("Annotating entities")
| Named entities are provided in the #[+a("/api/annotation#biluo") BILUO]
| notation. Tokens outside an entity are set to #[code "O"] and tokens
| that are part of an entity are set to the entity label, prefixed by the
| BILUO marker. For example #[code "B-ORG"] describes the first token of
| a multi-token #[code ORG] entity and #[code "U-PERSON"] a single
| token representing a #[code PERSON] entity
