NPL, or Natural Language Processing, is a field of artificial intelligence that focuses on the interaction between computers and human language. It enables machines to understand, interpret, and generate human language in a way that is both meaningful and useful. NPL is used in various applications, such as chatbots, translation services, and voice recognition systems. The goal of NPL is to bridge the gap between human communication and computer understanding. By utilizing techniques from linguistics and machine learning, NPL helps computers analyze text, recognize speech, and even respond to queries in a conversational manner. This technology is essential for improving user experiences in many digital platforms.
