The title pretty says it all...
We are using spacy in spanish to preprocess a series of texts and we need consistent nouns across our documents.
For instance, we would need to normalize "clienta" to "cliente" and so on
doc = nlp('la clienta ha pedido una coca cola')
for token in doc:
print(token.text, token.lemma_, token.base_form_)
where base_form should be some sort of a normalised, masculine version of the noun
