Xi Wang is a Lecturer of Natural Language Processing at the ±¬ÁÏTV. Previously, he obtained his PhD from the University of Glasgow, supervised by and and focused on the research topic of developing review text-based recommender systems. After that, he joined the web intelligence group of University College London (UCL) as a postdoctoral researcher, supervised by and worked on knowledge-augmented task-oriented dialogue systems. His current research interests are conversational AI, personalisation, and retrieval augmented generation, fairness, as well as relevant topics in the domain of natural language processing (NLP).
