For POS tagging, I am using spacy. I found pos tags for gerund and infinitives are not given. How can I add these two new tags in spacy? I can change tags within the list but not able to add new tags. Please help. Thank you.
**pattern = [tokens[t].pos_== "VERB" and tokens[t-1].pos_=="ADP" for t in range
(len(tokens)-1)]
spacy.pipeline.tagger.Tagger.add_label(u"GERUND")**
this gives error:
TypeError: add_label() takes exactly 2 positional arguments (1 given)
