spacy - 使用 spacy.matcher.matcher.Matcher.add() 方法的问题

Question

尝试使用 spacy matcher 时出现错误:

~\Anaconda3\lib\site-packages\spacy\matcher\matcher.pyx in spacy.matcher.matcher.Matcher.add()
TypeError: add() takes exactly 2 positional arguments (3 given)

spacy.matcher.matcher.Matcher.add() 是否有替代功能？ ?

见 SpaCy Matcher.add() documentation :

Changed in v3.0
As of spaCy v3.0, Matcher.add takes a list of patterns as the second argument (instead of a variable number of arguments). The on_match callback becomes an optional keyword argument.

patterns = [[{"TEXT": "Google"}, {"TEXT": "Now"}], [{"TEXT": "GoogleNow"}]] - matcher.add("GoogleNow", on_match, *patterns) + matcher.add("GoogleNow", patterns, on_match=on_match)

用法示例:

from spacy.matcher import Matcher

matcher = Matcher(nlp.vocab)
pattern = [{"LOWER": "hello"}, {"LOWER": "world"}]
matcher.add("HelloWorld", [pattern])
doc = nlp("hello world!")
matches = matcher(doc)
