Lemmatization is the process of reducing a word to its base or dictionary form, known as its lemma. This technique ensures that different forms of a word are treated as the same, which helps improve the understanding and processing of text data. By converting words to their root forms, lemmatization plays a vital role in text normalization, enhances the accuracy of part-of-speech tagging, and improves information retrieval systems by ensuring consistency in word representation.
