Natural Language Processing (NLP) is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human (natural) languages. As such, NLP is related to the area of human-computer interaction. Many challenges in NLP involve natural language understanding, that is, enabling computers to derive meaning from human or natural language input.

Key Areas of NLP

  • Tokenization: Splitting text into words, phrases, symbols, or other meaningful elements called tokens.
  • Part-of-Speech Tagging: Labeling words with their grammatical roles in a sentence.
  • Named Entity Recognition (NER): Identifying entities such as names, places, and organizations in text.
  • Sentiment Analysis: Determining whether a piece of text is positive, negative, or neutral.
  • Machine Translation: Automatically translating text from one language to another.

NLP is used in a variety of applications, including:

  • Chatbots: Automated conversation agents that can provide customer service or engage with users in a conversational manner.
  • Voice Assistants: Software applications that can recognize and respond to spoken commands, such as Apple's Siri or Amazon's Alexa.
  • Search Engines: Improving search results by understanding the intent behind user queries.
  • Language Models: Generating coherent and contextually appropriate text, as seen in applications like GPT-3.
