ReviewGraph – Using Knowledge Graphs to Predict Customer Satisfaction and Extract Hidden Insights
Lifeng Han will present ReviewGraph, a graph-based framework that transforms customer reviews into knowledge graphs to predict ratings and uncover hidden insights. He will compare this approach with traditional NLP methods and LLMs, highlighting how knowledge graphs offer strong performance with lower computational cost, greater interpretability, and promising integration with RAG systems.
Lifeng Han – Researcher, 4D Picture Project. Dr. Han has authored 50+ peer-reviewed publications and previously worked at the University of Manchester on Healthcare NLP. His PhD focused on machine translation (ADAPT Centre, DCU, Ireland).
