Natural Language Processing Trivia 3

Question 1

Which NLP task assigns grammatical roles like noun, verb, and adjective to words?

Accepted Answer

Part-of-speech tagging

Answer

Part-of-speech (POS) tagging labels each word in a sentence with its grammatical category such as noun, verb, adjective, or adverb.

Question 2

What is 'word sense disambiguation' in NLP?

Accepted Answer

Determining which meaning of a polysemous word is used in context

Answer

Word sense disambiguation (WSD) identifies which meaning of a word with multiple meanings is intended based on surrounding context.

Question 3

In machine translation, what does BLEU score measure?

Accepted Answer

The similarity between machine-translated and reference human translations

Answer

BLEU (Bilingual Evaluation Understudy) measures translation quality by comparing n-gram overlap between machine output and human reference translations.

Question 4

Which technique reduces a word to its base or dictionary form, e.g., 'running' → 'run'?

Accepted Answer

Lemmatization

Answer

Lemmatization reduces a word to its canonical dictionary form (lemma) using vocabulary and morphological analysis, unlike stemming which simply chops suffixes.

Question 5

What is the primary purpose of stop word removal in NLP preprocessing?

Accepted Answer

To eliminate common words that carry little meaningful information

Answer

Stop word removal filters out very common words like 'the,' 'is,' and 'in' that typically don't contribute meaningful information for many NLP tasks.
