Natural language processing (NLP) faces several challenges and limitations, primarily due to the complexity and variability of human language.
Ambiguity: Words or sentences can have multiple meanings depending on context. For example, "bank" could refer to a financial institution or the side of a river. Resolving such ambiguities requires deep contextual understanding.
Sarcasm and Irony: Detecting sarcasm or irony is difficult because the literal meaning often contradicts the intended meaning. For instance, saying "Great job!" in a frustrated tone implies the opposite.
Linguistic Diversity: Languages have different grammar rules, idioms, and cultural nuances. An NLP model trained on English may struggle with Chinese or Arabic due to structural differences.
Data Sparsity: Rare words, dialects, or domain-specific jargon may lack sufficient training data, leading to poor model performance. For example, medical or legal texts often contain specialized terminology.
Real-Time Processing: NLP systems must process and respond quickly, especially in applications like chatbots or voice assistants. Delays can degrade user experience.
Bias and Fairness: Models trained on biased datasets may produce discriminatory outputs. For example, gender bias in hiring-related NLP tools can favor male candidates.
Example: A sentiment analysis model might misclassify a sarcastic tweet as positive, leading to incorrect insights.
