Hello, I’m Jaeuk Han.
I am an undergraduate in the AI · Software Department at Gachon University and an undergraduate RA at the ISNLP Lab.
My interests include Natural Language Processing (NLP), Information Retrieval (IR), and Reinforcement Learning (RL), with a focus on reproducible experiments and practical system building.
RAG Systems: Korean-focused dual-encoder + reranker pipelines and evidence-grounded Q&A demos.
LLM Agents: Experiments combining LLM reasoning with RL training/evaluation in a Pokémon environment.
Data Engineering: End-to-end pipelines for crawling, parsing, unit/notation normalization, and metadata enrichment.
I’m also interested in how technology can support culture and education. For example, I structured historical manuscripts on Korean traditional liquors (886–1947) into a searchable knowledge base and built interactive demos based on it.
Long-term, I aim to bridge technology and culture as a researcher-developer, contributing to open source and sharing knowledge consistently (GitHub, Kaggle, blog).
