我正在尝试使用Spacy的Matcher来满足工作要求，以便我能够找到雇主正在寻找的经验年限。

# Initialize the Matcher with the shared vocabulary
matcher = Matcher(nlp.vocab)
# Create a pattern matching the tokens
pattern = [{'IS_DIGIT':True}, {"LEMMA": "year", 'POS':'NOUN'}]
pattern1 = [{'IS_DIGIT': True},{'TEXT':'-'},{'IS_DIGIT':True},{"LEMMA": "year", 'POS':'NOUN'}]
pattern2 = [{'IS_DIGIT': True},{'TEXT':'to'},{'IS_DIGIT':True},{"LEMMA": "year", 'POS':'NOUN'}]
pattern3 = [{'IS_DIGIT': True},{'TEXT':'or'},{'IS_DIGIT':True},{"LEMMA": "year", 'POS':'NOUN'}]
pattern4 = [{'IS_DIGIT': True},{'TEXT':'+'},{"LEMMA": "year", 'POS':'NOUN'}]
pattern5 = [{'IS_ALPHA': True},{'TEXT':'('},{'IS_DIGIT': True},{'TEXT':')'},{'TEXT':'to'},{'IS_ALPHA':True},{'TEXT':'('},{'IS_DIGIT': True},{'TEXT':')'},{"LEMMA": "year", 'POS':'NOUN'}]
pattern6 = [{'lower':'fresh grads'}]
# Add the pattern to the matcher
matcher.add("x years", None, pattern)
matcher.add("z - x years", None, pattern1)
matcher.add("z to x years", None, pattern2)
matcher.add("z or y years",None, pattern3)
matcher.add('x+ years', None, pattern4)
matcher.add('alpha(digit) to alpha(digit) years', None, pattern5)
# Use the matcher on the doc
matches = matcher(doc)
matched = [doc[start:end].text for match_id, start, end in matches]
print("Matches:", matched)
对于最后一个模式 pattern6，我正在尝试匹配应届毕业生，所以当我在要求中获得应届毕业生时，它只会打印出 0 年的经验，但如果不是，它只会打印出任何匹配的句子。无论如何，我可以使用 if else 语句，如果触发 pattern6，那么它将打印匹配项：0 年？
提前谢谢你！
Matcher本身没有办法做到这一点。您需要运行匹配器，分析结果以查看哪些模式匹配，如果未找到任何模式，则输出"0 年"(例如(。
另外，请记住，Matcher模式适用于单个令牌，因此由于中间的空间{"lower": "fresh grads"}不会匹配任何内容。您需要将其拆分为两种令牌模式。
