spaCy - 按标签对实体进行排序的最有效方法
spaCy - Most efficient way to sort entities by label
我正在使用 spaCy 管道从文章中提取所有实体。我需要根据标记它们的标签将这些实体保存在一个变量上。现在我有了这个解决方案,但我认为这不是最合适的,因为我需要遍历每个标签的所有实体:
nlp = spacy.load("es_core_news_md")
text = # I upload my text here
doc = nlp(text)
personEntities = list(set([e.text for e in doc.ents if e.label_ == "PER"]))
locationEntities = list(set([e.text for e in doc.ents if e.label_ == "LOC"]))
organizationEntities = list(set([e.text for e in doc.ents if e.label_ == "ORG"]))
spaCy 中是否有直接方法来获取每个标签的所有实体,或者我是否需要 for ent in ents: if... elif... elif...
才能实现?
我建议使用 itertools
:
中的 groupby
方法
from itertools import *
#...
entities = {key: list(g) for key, g in groupby(sorted(doc.ents, key=lambda x: x.label_), lambda x: x.label_)}
或者,如果您只需要提取唯一值:
entities = {key: list(set(map(lambda x: str(x), g))) for key, g in groupby(sorted(doc.ents, key=lambda x: x.label_), lambda x: x.label_)}
然后,您可以使用
打印已知实体
print(entities['ORG'])
如果您需要获取实体 objects 的唯一出现,而不仅仅是 strings,您可以使用
import spacy
from itertools import *
nlp = spacy.load("en_core_web_sm")
s = "Hello, Mr. Wood! We are in New York. Mrs. Winston is not coming, John hasn't sent her any invite. They will meet in California next time. General Motors and Toyota are companies."
doc = nlp(s * 2)
entities = dict()
for key, g in groupby(sorted(doc.ents, key=lambda x: x.label_), lambda x: x.label_):
seen = set()
l = []
for ent in list(g):
if ent.text not in seen:
seen.add(ent.text)
l.append(ent)
entities[key] = l
此处 print(entities['GPE'][0].text)
的输出为 New York
。
