Enhancing Customer Service Automation with Natural Language Processing and Reinforcement Learning Algorithms

Abstract

This research paper explores the integration of natural language processing (NLP) and reinforcement learning (RL) algorithms to enhance customer service automation, addressing the demand for more sophisticated and human-like interactions in automated systems. The study begins by reviewing current customer service technologies and identifying limitations in handling complex queries and adapting to diverse customer needs. It then proposes a novel framework that combines NLP for understanding and generating natural language and RL for dynamically improving the system's performance through feedback and experience. The framework is designed to improve both response accuracy and user satisfaction by learning from interactions in real time. An experimental setup is developed, implementing the proposed approach using a dataset of customer interactions from a leading service provider. The system's performance is evaluated against traditional rule-based and machine learning models using metrics such as response correctness, user satisfaction scores, and operational efficiency. Results demonstrate that the integrated NLP-RL approach significantly outperforms existing models, particularly in scenarios involving multi-turn dialogues and unforeseen user intents. The paper concludes by discussing the implications of these findings for the future of customer service automation, including potential challenges in scalability and ethical considerations, and suggests avenues for further research to refine and expand the proposed system.
