Chatbots leverage natural language processing (NLP) to understand and respond to user queries effectively. NLP enables chatbots to analyze input text, recognizing intent and extracting relevant information. By employing algorithms and models, chatbots can parse language nuances, handling synonyms and varying expressions. This comprehension allows them to provide accurate responses or escalate issues to human agents when needed. Additionally, chatbots improve over time via machine learning, refining their interactions based on user feedback and previous conversations. The result is a more intuitive and engaging experience for users, facilitating efficient customer service and information retrieval.
