+h(3, "json-input") JSON input format for training
|
|
|
|
p
|
|
| 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. The
|
|
| #[+api("goldparse#biluo_tags_from_offsets") #[code biluo_tags_from_offsets]]
|
|
| function can help you convert entity offsets to the right format.

| #[+api("cli#vocab") #[code spacy vocab]] command and load in a
|
|
| #[+a("https://jsonlines.readthedocs.io/en/latest/") newline-delimited JSON]
|
|
| (JSONL) file containing one lexical entry per line. The first line
|
|
| defines the language and vocabulary settings. All other lines are
|
|
| expected to be JSON objects describing an individual lexeme. The lexical
|
|
| attributes will be then set as attributes on spaCy's
|
|
| #[+api("lexeme#attributes") #[code Lexeme]] object. The #[code vocab]
|
|
| command outputs a ready-to-use spaCy model with a #[code Vocab]
