Spacy PhraseMatcher值错误模式长度(11)> = phrase_matcher.max_length(10)

Question

初始化带有术语列表的新PhraseMatcher时出现以下错误:

ValueError:Pattern length(11)> = phrase_matcher.max_length(10).长度可以在初始化时设置,最多10个.

patterns = [nlp(org) for org in fields]
        self.matcher = PhraseMatcher(nlp.vocab)
        self.matcher.add('FIELD', None, *patterns)

Answer 1

目前,单个规则的长度不能超过10个令牌:

# Allowed
'one two three four five six seven eight nine ten'
# Not Allowed
'one two three four five six seven eight nine ten eleven'

您可以尝试将限制设置为更高,即:self.matcher = PhraseMatcher(nlp.vocab, max_length=20),但在当前版本的SpaCy 10中的iirc是一个硬限制.
