Which of the following statements correctly differentiates stemming from lemmatization in Natural Language Processing?
- 1Both stemming and lemmatization strictly require part-of-speech tagging for every processed word.
- 2Stemming reduces words to a crude root form that may not be a valid word, whereas lemmatization returns valid dictionary words (lemmas).✓
- 3Lemmatization is computationally faster but less accurate than stemming.
- 4Stemming uses dictionary-based linguistic rules, while lemmatization simply removes word suffixes.
Correct answer
Stemming reduces words to a crude root form that may not be a valid word, whereas lemmatization returns valid dictionary words (lemmas).
