Which comes first in order of implementation: POS Tagging or Lemmatisation?
Sure make the POS Tagger first. If you do lemmatisation first you could lose the best possible classification of words when doing the POS Tagger, especially in languages where ambiguity is commonplace, as it is in Portuguese.
If I wanted to make a NLP Toolkit like NLTK, which features would I implement first after tokenisation and normalisation. POS Tagging or Lemmatisation?
