Natural Language Processing (NLP)
NLP lets computers understand human language—both the words we say and the ones we write.
It allows machines to talk, read, and answer questions just like people do.
For example, when you ask Siri or Alexa “What’s the weather today?” they use NLP to understand
your question and give you an answer.
Some applications of NLP are as follows:
• Voice assistants: Like Siri or Alexa, they answer questions using spoken language.
• Chatbots: Online helpers that respond to customer questions instantly.
• Language translation apps: Translate text or speech from one language to another.
• Spam email filters: Sort emails and block unwanted spam messages.
• Voice-to-text conversion: Converts spoken words into written text on phones or computers.
• Sentiment analysis: Understands if a social media post or review is positive or negative.
• Autocorrect and spell-check: Suggests correct spellings while typing.
Statistical Data
AI also learns by looking at large amount of data and finding patterns. This helps AI make smart
decisions, predict what might happen next, and improve itself over time.
