What is the best stemming method in Python?
The goal of both stemming and lemmatization is to reduce inflectional forms and sometimes derivationally related forms of a word to a common base form. For instance: am, are, is -> be car, cars, car's, cars' -> car The result of this mapping of text will be something like: the boy's cars are different colors -> the boy car be differ color How do I do word Stemming or Lemmatization?
