Natural language processing

Definition

Natural language processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and humans through natural language. It combines computational linguistics, computer science, and cognitive psychology to enable machines to understand, interpret, and respond to human language in a valuable way. This technology plays a significant role in various applications, such as chatbots, translation services, and sentiment analysis, affecting how we engage with digital media and understand human cognition.

5 Must Know Facts For Your Next Test

1. Natural language processing allows machines to interpret context, grammar, and semantics, making it essential for developing intelligent conversational agents.
2. NLP techniques are widely used in digital media for applications such as voice recognition, search engines, and personalized content recommendations.
3. One of the significant challenges in NLP is dealing with the ambiguity and variability of human language, including slang, dialects, and idiomatic expressions.
4. Recent advancements in deep learning have significantly improved the capabilities of NLP systems, enabling them to perform complex tasks like translation with higher accuracy.
5. NLP has important implications in psycholinguistics as it helps researchers understand how language processing occurs in the human brain by simulating language understanding.

Review Questions
