Conversational AI

What is Natural Language Processing (NLP)?

Natural Language Processing (NLP) is a branch of Artificial Intelligence (AI) that focuses on enabling computers to understand, interpret, and respond to human language. By bridging the gap between human communication and machine understanding, NLP powers applications like chatbots, language translation, and sentiment analysis.

Why is it Important?

NLP is crucial in making interactions with technology more natural and intuitive. It enables businesses to analyze customer feedback, automate workflows, and improve accessibility. From voice-activated assistants to predictive text, NLP enhances user experiences across industries.

How is This Metric Managed and Where is it Used?

NLP models are developed using techniques like tokenization, part-of-speech tagging, and dependency parsing. Managed through pre-trained models and fine-tuning, NLP is widely used in customer support, healthcare (clinical documentation), marketing (sentiment analysis), and education (automated grading).

Key Elements

  • Tokenization: Breaking text into smaller units like words or sentences.
  • Part-of-Speech (POS) Tagging: Identifying grammatical roles of words.
  • Named Entity Recognition (NER): Extracting entities like names, dates, or locations.
  • Sentiment Analysis: Determining the emotional tone of text.
  • Language Models: Pre-trained systems like GPT and BERT for understanding text.
