About MeI'm an associate professor in Computer Engineering at the Dong-A University. I joined the faculty in September 2004, after completing my Ph.D in Computer Science at the Sogang University in August 2003.
I work at the intersection of natural language processing (NLP) and information retrieval (IR), and I am interested in NLP (dialogue system etc), IR (cross-language IR etc), text mining (text classification/summarization etc), opinion mining (comparison mining, sentiment classification etc), big data (topic modeling and machine learning etc) and UI/UX. I'm leading the Information Systems Laboratory at the Dong-A University. For more details, please see my CV.
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.
