In natural language processing, Lemmatization is the operation of grouping together the inflected forms of a word so they can be analyzed as a single item, identified by the word’s lemma, or dictionary form.

Example: In English, run, runs, ran and running are different forms of run, the lemma by which all four terms are indexed.
