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 involves enabling computers to understand, interpret, and respond to human languages in a valuable way, making it a key player in automating communication and information retrieval. NLP uses algorithms and models to analyze human language patterns, allowing for applications like chatbots, voice recognition, and sentiment analysis.

5 Must Know Facts For Your Next Test

1. NLP combines computational linguistics with machine learning techniques to analyze human language.
2. One major application of NLP is in virtual assistants like Siri and Alexa, which use voice recognition to understand user commands.
3. NLP can automatically translate languages using algorithms that learn from vast datasets of bilingual text.
4. Text summarization is another application of NLP, allowing systems to condense long documents into shorter summaries while retaining key information.
5. NLP faces challenges such as understanding context, sarcasm, and ambiguity in human language, making it a complex area of study.

Review Questions
