What is difference between stemming and lemmatization?

  • Stemming helps reduce a word to its stem form — It removes suffices, like “ing”, “ly”, “s”, etc.But it often the actual words get neglected. eg: Entitling,Entitled->Entitl
  • Stemming is faster as it chops the end of the word, without understanding the context of the word.
  • Lemmatizing derives the canonical form (‘lemma’) of a word. Morphological analysis to the root form — Entitling, Entitled->Entitle
  • Lemmatizing is slower and more accurate and it takes context of the word in mind.
