Multi-Hop GraphRAG over Knowledge Graphs
Developed path-preserving beam search and evidence reranking for multi-hop question answering during my research internship at ETRI.
I am an undergraduate studying Computer Engineering and Information Statistics at Duksung Women’s University, with expected graduation in February 2027. Most recently, I was a research intern at ETRI, working on knowledge graphs and multi-hop GraphRAG. Previously, I conducted research on LLM reasoning and document understanding at DMKD Lab under the supervision of Prof. Jehyeok Rew, and on low-light human pose estimation in the Vision and Multimodal Intelligence Lab at the University of Mississippi under the supervision of Prof. Hawk Wang. I also worked at BCG, analyzing data for a global battery manufacturer. Here is my CV.
My research spans document understanding, LLM reasoning, and retrieval-augmented generation. Building on my work in document structure analysis (CoDU) and efficient prompting (SPTC), my recent work on multi-hop GraphRAG over knowledge graphs at ETRI focuses on retrieving and connecting evidence for multi-hop question answering.
