In recent times, there has been a significant rethinking of enterprise management, which is increasingly based on customer insight. Customer insight management is crucial to facing today’s business challenges. The adoption and application of sentiment analysis (SA) in modern business environments has attracted significant interest in interpreting real-time analyses of customer insights, which offers tremendous opportunities for enhancing decision-making processes. Recent SA methods of pre-trained machine learning and deep learning models cannot perform efficiently for complex linguistic phenomena. Our paper proposed an integrated large language model (LLM) based novel strategy for SA into an enterprise system. Toward this, we used the information systems (IS) computational design science paradigm to develop a two-stage fused-distillation framework of LLM agents from customer insight. We also utilized instruction-following prompts to understand the interpretibility of the fused-distillation framework. Our analysis of three public datasets showed that our framework achieved high precision (acc-95%) in SA and offered the latest LLM-based enterprise-level solutions and methodological advancements.
