一行中的所有匹配项：Spacy matcher

Question

I am looking for a solution to print all the matching in a line using Spacy matcher

The example goes like this, Here I am trying to extract experience.

doc = nlp("1+ years of experience in XX, 2 years of experiance in YY")
pattern = [{'POS': 'NUM'}, {'ORTH': '+', "OP": "?"}, {"LOWER": {"REGEX": "years?|months?"}}]
matcher = Matcher(nlp.vocab)
matcher.add("Skills", None, pattern)
matches = matcher(doc)
pirnt(doc[matches[0][1]:matches[0][2]]

Here I am getting output 1+ years .

But I am looking for a solution having output ['1+ years','2 years']

Answer 1

You should specify the first item as 'LIKE_NUM': True :

pattern = [{'LIKE_NUM': True}, {'ORTH': '+', "OP": "?"}, {"LOWER": {"REGEX": "(?:year|month)s?"}}]

I also contracted the years?|months? to (?:year|month)s? , you might even consider matching full token string using ^(?:year|month)s?$ , but that is not necessary at this point.

Code:

import spacy
from spacy.matcher import Matcher

nlp = spacy.load("en_core_web_sm")
matcher = Matcher(nlp.vocab)
pattern = [{'LIKE_NUM': True}, {'ORTH': '+', "OP": "?"}, {"LOWER": {"REGEX": "(?:year|month)s?"}}]
matcher.add("Skills", None, pattern)

doc = nlp("1+ years of experience in XX, 2 years of experiance in YY")

matches = matcher(doc)
for _, start, end in matches:
  print(doc[start:end].text)

Output:

1+ years
2 years
