Lemmatizer is an algorithm in morphological analysis and computational linguistics which identifies the lemma (or the dictionary form) of a word. In lemmatization, all the inflected forms of a word are grouped together so that they can be identified as a single item.
Lemmatization algorithms identify the intended part of speech as well as the meaning of a word in a sentence, as also in a larger context in the surrounding sentences and even the entire document.
