How can I get this to work? about negspacy HOT 4 CLOSED

Hi - there could be two issues here:

1. you're limiting the entity types to PERSON or ORG that you're doing negation on.
2. Even if you weren't limiting types, there are no entities in the example that show up using "en_core_web_sm".

You can create and entity ruler . See the example below where football is negated by cannot which is a preceding term in the "en" termset. If you want to change termsets, see this example.

import spacy
from negspacy.negation import Negex
from negspacy.termsets import termset

ts = termset("en")

nlp = spacy.load("en_core_web_sm")

ruler = nlp.add_pipe("entity_ruler")
patterns = [{"label": "SPORT", "pattern": "football"},
            {"label": "SPORT", "pattern": [{"LOWER": "ice"}, {"LOWER": "hockey"}]}]
ruler.add_patterns(patterns)

nlp.add_pipe(
    "negex",
    config={
        "neg_termset":ts.get_patterns()
    }
)

doc = nlp("Men cannot play football.")

for e in doc.ents:
    print(e.text, e._.negex)

Thanks so much for your help! This makes sense. Apologies for the delay in getting back to you.

Although, if I replace 'football' with 'hockey' in the doc - nothing is returned - am I missing something else?

Huge apologies, I'm very new to this and learning.

So for the example code I pasted above, it's looking specifically for 'ice hockey' not just 'hockey'. If you changed the patterns to remove 'ice' as shown below then it would work.

            {"label": "SPORT", "pattern": [{"LOWER": "hockey"}]}]

Thanks @jenojp, this is really helpful!
