Natural Language Processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and humans through natural language. It involves the ability of machines to understand, interpret, and generate human language.

Key Components of NLP

  • Text Preprocessing: This involves cleaning and preparing text data for analysis. It includes tasks like tokenization, stemming, and lemmatization.
  • Language Modeling: This is the process of creating a model that can predict the probability of a sequence of words given a previous sequence.
  • Sentiment Analysis: This involves determining the sentiment or opinion of a piece of text, such as a review or a social media post.
  • Machine Translation: This is the process of translating text from one language to another using computational methods.

Applications of NLP

  • Search Engines: NLP is used to improve the accuracy and relevance of search results.
  • Chatbots: NLP enables chatbots to understand and respond to user queries in a natural language.
  • Voice Assistants: NLP is used to process and understand spoken language, allowing voice assistants to perform tasks like setting reminders or answering questions.
