| A named entity is a "real-world object" that's assigned a name – for
|
|||
|
|
| example, a person, a country, a product or a book title. spaCy can
|
|||
|
|
| #[strong recognise] #[+a("/docs/api/annotation#named-entities") various types]
|
|||
|
|
| of named entities in a document, by asking the model for a
|
|||
|
|
| #[strong prediction]. Because models are statistical and strongly depend
|
|||
|
|
| on the examples they were trained on, this doesn't always work
|
|||
|
|
| #[em perfectly] and might need some tuning later, depending on your use
|
|||
|
|
| case.
|
|||
|
|
|
|||
|
|
p
|
|||
|
|
| Named entities are available as the #[code ents] property of a #[code Doc]:
|
|||
|
|
|
|||
|
|
+code.
|
|||
|
|
doc = nlp(u'Apple is looking at buying U.K. startup for $1 billion')
|
|||
|
|
|
|||
|
|
for ent in doc.ents:
|
|||
|
|
print(ent.text, ent.start_char, ent.end_char, ent.label_)
|
|||
|
|
|
|||
|
|
+aside
|
|||
|
|
| #[strong Text]: The original entity text.#[br]
|
|||
|
|
| #[strong Start]: Index of start of entity in the #[code Doc].#[br]
|
|||
|
|
| #[strong End]: Index of end of entity in the #[code Doc].#[br]
|
|||
|
|
| #[strong Label]: Entity label, i.e. type.

|
|||
|
|
| here's what our example sentence and its named entities look like:
|
|||
|
|
|

|
|
+codepen("2f2ad1408ff79fc6a326ea3aedbb353b", 160)
