Abstract

This paper explores the application of natural language processing (NLP) techniques to improve the performance and user experience of customer service chatbots. Chatbots are increasingly being deployed by companies to provide 24/7 customer support and handle common queries. However, many chatbots still struggle to engage in natural conversations and accurately understand and address customer needs. We propose leveraging advanced NLP methods including intent classification, named entity recognition, sentiment analysis, and dialogue management to enable chatbots to better comprehend user messages and provide more helpful and personalized responses. We present a modular framework for building NLP-powered chatbots and demonstrate its effectiveness through experiments across diverse customer service domains. Results show that our NLP techniques significantly enhance chatbot performance on key metrics such as intent understanding accuracy, user query resolution rate, conversation quality, and overall customer satisfaction compared to traditional rule-based and retrieval-based chatbots. Our work illustrates the immense potential of NLP to empower intelligent, scalable, and user-friendly chatbot systems that can strengthen customer relationships and support.
