Natural language processing (NLP) is key for chatbots to understand human language and have natural conversations. As messaging platforms are used more than social networks, with 77% of Generation Z and 50% of people preferring to contact businesses through chat over the phone, businesses need chatbots to provide customer service through these popular channels. For chatbots to be successful, they must have integrated natural language processing, good UX/UI design, and connect to various APIs and services to handle tasks like making reservations, answering questions about products, and more.
