I work at the intersection of natural language processing (NLP) and information retrieval (IR) based on Language Models, and I am interested in NLP (dialogue system, question/answering system, etc.), IR (GraphRAG, etc.), Generative AI (controllable text generation, etc.), Machine learning for AI (reinforcement learning, etc), and Text Mining (text classification/summarization, sentiment classification, etc.) for Agentic and Physical AI. I'm leading the Natural Language Processing (NLP) Laboratory at College of Computing and Informatics of Sungkyunkwan University. I worked at the Computational Linguistics and Information Processing Laboratory (CLIP) at the University of Maryland, College Park as a visiting scholar from 2011 fall semester to 2012 spring semester. My collaborator was Prof. Doug Oard. Videos for my talks "ChatGPT란 무엇인가? [Part I and Part II]" at 성대의 성대한 특강 and "Neural Symbolic AI" at SKKU AI Colloquium.
