← Language & CommunicationWhy does a sentiment analysis algorithm assessing online restaurant reviews fail to correctly classify sarcasm?
A)Lexical choice prevents statistical weighting
B)Tokenization ignores word embedding contexts
C)Semantic inversion creates polarity contradiction✓
D)Stop word removal impacts negation detection
💡 Explanation
Sentiment analysis fails with sarcasm because semantic inversion causes a contradiction between the literal meaning and the intended sentiment. The algorithm struggles to detect this reversal; therefore, it misclassifies the review, rather than detecting subtle contextual cues or negation effectively.
