Lemmatization technique is like stemming. The output we will get after lemmatization is called ‘lemma’, which is a root word rather than root stem, the output of stemming. After lemmatization, we will be getting a valid word that means the same thing. NLTK provides WordNetLemmatizer class which is a thin wrapper around the wordnet corpus.The NLTK Lemmatization method is based on WordNet’s built-in morph function. We write some code to import the WordNet Lemmatizer. from nltk.stem import WordNetLemmatizer nltk.download('wordnet') # Since Lemmatization is based on WordNet's built-in morph function. Now that we have downloaded the wordnet, we can go ahead with lemmatization.NLTK is written in Python and distributed under the GPL open source license.
