Answer 2

"Stemming and Lemmatization" are the "NLP technique uses the lexical knowledge" base to obtain the "correct base form of the words".

Explanation:

"Stemming and lemmatization" are  the two main approaches to handle "inflections in search queries". The "well-known and very most popular stemming" technique for English is the "Porter stemming algorithm", also called as the "Porter stemmer".

"Lemmatization" attends to take a similarly "careful approach to remove inflections". In general, lemmatization gives "better precision than stemming", but at the "expense of recall".
