SpaCy: How to manually set POS tag for vertical bar "|"?

Question

When text is tagged by SpaCy, the vertical bar "|" is assigned different POS tags depending on the context, such as "ADV" , "DEL"... While I want "|" to be recognized as "PUNC". Is there a way to force this POS for "|" ?

I tried this command and it didn't work.

nlp.tokenizer.add_special_case('|', [{ORTH: '|', POS: PUNC}])

Answer 1

I would add a simple pipe into the pipeline, right after the tagger :

def pos_postprocessor_pipe(doc) :
    for token in doc :
        if token.text == '|':
            token.pos_ = 'PUNCT'
    return doc

 nlp = spacy.load("en_core_web_sm")
 nlp.add_pipe(pos_postprocessor_pipe, name="pos_postprocessor", after='tagger')
