spacy Entityruler 的正则表达式模式不起作用

Question

我正在尝试使用正则表达式识别实体并使用实体标尺标记它们。正则表达式模式 return 与 Matcher 匹配，但 return 与实体标尺不同，并且也适用于普通正则表达式。

    from spacy.matcher import Matcher
    text = u"Name: first last \n Phone: +1223456790 \n e-mail: first.last@testmail.com."
    doc = nlp(text)
    matcher = Matcher(nlp.vocab)
    pattern = [{"LOWER": {'REGEX' :"\w+\.\w+\@\w+\.com"}}]
    matcher.add("email", None, pattern)
    matches = matcher(doc)
    print([doc[start:end] for match_id, start, end in matches])

输出： [first.last@testmail.com]

`

text = u"Name: first last \n Phone: +1223456790 \n e-mail: first.last@testmail.com."
from spacy.lang.en import English
from spacy.pipeline import EntityRuler
nlp = English()
ruler = EntityRuler(nlp, overwrite_ents=True)
pattern = [{"label": "Email", "pattern":
            {"LOWER": {'REGEX' : "\w+\.\w+\@\w+\.com"}}
           }]

ruler.add_patterns(patterns)
nlp.add_pipe(ruler, name='customer')
text = u"Name: first last \n Phone: +1223456790 \n e-mail: first.last@testmail.com."
doc = nlp(text)
for ent in doc.ents:
    print(ent.text,ent.label_)

` 输出： None

Answer 1

EntityRuler 模式需要作为令牌指令列表提供，就像 Matcher 模式中一样：

pattern = [{"label": "Email", "pattern":
            [{"LOWER": {'REGEX' : "\w+\.\w+\@\w+\.com"}}]
           }]
