The slide "3. Applications of NLP" presents a feature grid highlighting key NLP uses: Sentiment Analysis for detecting emotions in reviews and social media; Text Classification for categorizing documents like spam detection; Machine Translation for cross-language translation; and Named Entity Recognition for extracting entities from text. These applications demonstrate practical NLP capabilities in analysis, categorization, translation, and entity extraction.

3. Applications of NLP

NLP faces key challenges like word ambiguity, context dependency, sarcasm detection, and handling multilingual data. Advances in AI research include transformers (BERT, GPT), transfer learning, large language models, and improved accuracy in sentiment analysis, translation, and NER.

4. Challenges & 5. Advances

| • Ambiguity: Words with multiple meanings confuse models

• Context: Dependency on surrounding words for interpretation
• Sarcasm: Detecting irony and tone is difficult
• Multilingual Data: Handling diverse languages and dialects | • Transformers (BERT, GPT): Revolutionize context understanding
• Transfer Learning: Pre-trained models for efficient adaptation
• Large Language Models: Scale for better performance
• Improved accuracy in sentiment, translation, and NER |
