LEMMATIZATION Meaning and
Definition
-
Lemmatization is a linguistic and computational process that involves reducing words to their base or root form, known as the lemma. It is performed as a part of natural language processing (NLP) and text analysis, aiming to simplify and standardize textual data. The lemma represents the canonical form of a word, disregarding its specific inflections or conjugations used in different contexts.
Unlike stemming, which also tries to reduce words to their base form, lemmatization considers the broader context and semantics of the word. This means that lemmatization tends to produce more accurate root forms, resulting in valid words that can be found in a dictionary. In order to determine the lemma of a word, lemmatization algorithms take into account factors such as the part of speech (POS) tag and surrounding words.
Lemmatization offers numerous benefits in various applications. It aids in tasks such as text classification, information retrieval, machine translation, and sentiment analysis. By reducing words to their lemmas, lemmatization can help to improve the accuracy of these tasks by capturing the core meaning and eliminating noise caused by different word forms.
Overall, lemmatization is a valuable technique in the field of computational linguistics, enabling better understanding and analysis of textual data by transforming words into their base forms while maintaining semantic integrity.

Etymology of LEMMATIZATION
The word "lemmatization" is derived from the Latin word "lemma", which means "something that is taken" or "premise". In linguistics and computational linguistics, a lemma refers to the base or root form of a word, usually found in dictionaries or lexicons, from which various inflected or derived forms are generated. "Lemmatization" is the process of determining and reducing words to their base or lemma form. The "-ization" suffix indicates the act or process of performing the action related to the preceding word, in this case, deriving lemmas.
