Natural language processing (Computational linguistics) - Quiz
Contributed by: Burrows
  • 1. Natural language processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and humans using natural language. It involves the development of algorithms and models that enable machines to understand, interpret, and generate human language. Computational linguistics is a subfield of NLP that combines linguistics and computer science to study human language and develop computational models for analyzing and processing linguistic data. Through NLP and computational linguistics, researchers aim to build systems that can perform tasks such as language translation, sentiment analysis, speech recognition, and text summarization. These technologies have a wide range of applications, from virtual assistants and chatbots to language processing tools for research and education.
