|
||||
| It's now much easier to customise the pipeline with your own components.
|
||||
| Components are functions that receive a #[code Doc] object, modify and
|
||||
| return it. If your component is stateful, you'll want to create a new one
|
||||
| for each pipeline. You can do that by defining and registering a factory
|
||||
| which receives the shared #[code Vocab] object and returns a component.
|
||||
|
||||
p
|
||||
| spaCy's default components – the vectorizer, tagger, parser and entity
|
||||
| recognizer, can be added to your pipeline by using their string IDs.
|
||||
| This way, you won't have to worry about finding and implementing them –
|
||||
| to use the default tagger, simply add #[code "tagger"] to the pipeline,
|
||||
| and spaCy will know what to do.
