What is NLP?
Natural Language Processing (NLP) is AI that lets machines understand, analyze, and generate human language. Think chatbots, translators, or Siri!
Key Techniques
- Tokenization: Split text into words/symbols.
- Stemming/Lemmatization: Reduce words to base forms (e.g., “running” → “run”).
- Sentiment Analysis: Detect emotions in text (👍/👎).
- Word Embeddings: Turn words into numbers (e.g., Word2Vec). Tools: Use libraries like spaCy or Hugging Face for tasks like translation, summarization, or entity recognition.
Challenges: Ambiguity (“bank” = river or money?), sarcasm, bias in data, and low-resource languages.
Why It Matters: Powers chatbots, voice assistants, real-time translation, and data analysis. Future trends include multimodal AI (text + images/audio) and ethical AI.
Start Now: Experiment with simple projects (e.g., tweet sentiment analysis) to unlock the magic of language + tech! 🚀
