Natural Language Processing

Definition

Natural Language Processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and human language, enabling machines to understand, interpret, and generate human language in a meaningful way. This capability is essential for extracting insights from vast amounts of unstructured text data, which is a crucial component of the Big Data ecosystem and value chain. NLP leverages techniques from linguistics, computer science, and machine learning to analyze text and speech, making it possible to automate tasks such as sentiment analysis, translation, and chatbots.
