Why does automatic sentiment analysis often fail to accurately classify the emotional tone of tweets containing Internet slang abbreviations (e.g., 'tbh', 'imo')?

💡 Explanation

Sentiment analysis struggles because Internet slang abbreviations undergo rapid contextual semantic drift; the meaning of 'tbh' changes over time and across social groups. Therefore, a fixed lexicon won't capture current usage, rather than reflecting simple substitution or a universally positive association.

• Why does neural machine translation sometimes generate translations with high BLEU scores but lack coherence?
• Why does a constructed language (conlang) like Esperanto often fail to achieve widespread adoption despite deliberate planning?
• Why does a literary translator adapting a 19th-century Russian novel for a modern American audience choose 'domestication' as their primary strategy, rather than literal translation?
• Why does adoption of a non-native accent increase perceived prestige in international call centers?
• A multilingual community abruptly adopts a simplified trade language (pidgin) as its primary means of communication. Which outcome becomes most probable over several generations?
• Why does native-like fluency emerge in second language acquisition following extensive exposure to and practice with common phrases and sentence stems?
