Abstract Natural Language Processing (NLP) is revolutionizing customer service by enabling
AI-driven systems to understand, interpret, and respond to human language with greater
accuracy. Pega’s AI-driven customer service solutions integrate NLP to enhance automated
interactions, optimize sentiment analysis, and improve customer engagement. This paper
examines the role of NLP in Pega’s AI-powered applications, comparing its effectiveness with
other industry solutions and analyzing its impact on response efficiency, personalization, and
customer satisfaction.
