In spaCy v2.x, the statistical components like the tagger or parser are
independent and don't share any data between themselves. For example, the named
entity recognizer doesn't use any features set by the tagger and parser, and so
on. This means that you can swap them, or remove single components from the
pipeline without affecting the others.
However, custom components may depend on annotations set by other components.
For example, a custom lemmatizer may need the part-of-speech tags assigned, so
it'll only work if it's added after the tagger. The parser will respect
pre-defined sentence boundaries, so if a previous component in the pipeline sets
them, its dependency predictions may be different. Similarly, it matters if you
add the [`EntityRuler`](/api/entityruler) before or after the statistical entity
recognizer: if it's added before, the entity recognizer will take the existing
entities into account when making predictions.
