The technology that underlies most chatbots is natural language processing (NLP). NLP enables chatbots to understand, interpret, and respond to user inputs in a conversational manner. This technology analyzes the syntax and semantics of the language, allowing the chatbot to process queries effectively. Additionally, many chatbots incorporate machine learning to improve their responses over time based on interactions with users. The combination of NLP and machine learning empowers chatbots to provide more accurate and contextually relevant responses, enhancing user experience and engagement across various applications, from customer service to personal assistants.
