Definition
The process of converting words to their dictionary base form (lemma) while considering context and part of speech.
Detailed Explanation
Unlike stemming, lemmatization uses vocabulary and morphological analysis to properly convert words to their base dictionary form. It considers the part of speech and context of words, ensuring that the resulting lemmas are actual words. For example, better becomes good, and running becomes run.
