EntityRuler adaugă entități denumite într-un container DocEntityRecognizer{"label": "ORG", "pattern": "Microsoft"}
{"label": "GPE", "pattern": [{"LOWER": "san"}, {"LOWER": "francisco"}]}
.add_pipe().add_patterns()
nlp = spacy.blank("en")
entity_ruler = nlp.add_pipe("entity_ruler")
patterns = [{"label": "ORG", "pattern": "Microsoft"},
{"label": "GPE", "pattern": [{"LOWER": "san"}, {"LOWER": "francisco"}]}]
entity_ruler.add_patterns(patterns)
.ents stochează rezultatele componentei EntityLinker
doc = nlp("Microsoft is hiring software developer in San Francisco.")
print([(ent.text, ent.label_) for ent in doc.ents])
[('Microsoft', 'ORG'), ('San Francisco', 'GPE')]
spaCyÎmbunătățește recunoașterea entităților denumite
