Natural Language Processing (NLP) facilitates chatbots by enabling them to understand and respond to human language more effectively. Through techniques like tokenization and sentiment analysis, NLP allows chatbots to parse input, grasp user intent, and generate relevant answers. This capability enhances user interaction by making conversations feel more natural and intuitive. By using machine learning models, NLP systems can continually improve their understanding of language, adapting to new phrases and contexts. As a result, NLP empowers chatbots to provide enhanced customer support and automate tasks, streamlining user experiences in various applications.
