초록

본 논문에서는 LLM과 RAG를 활용한 잠수함 전투체계 교범 질의응답 시스템 구축 방안을 제시한다. 문서 임베딩, 벡터 데이터베이스, fine-tuning을 포함한 파이프라인을 구성하고 객관식, 주관식 각 100문항의 벤치마크 데이터로 성능을 비교 평가하였다. 실험 결과 rag와 fine-tuning 적용 시 기본 모델 대비 응답 정확도와 문맥 적합성이 향상되었으며, 잠수함 전투체계 적용 가능성을 확인하였다.

Abstract

This paper proposes a method for large language model- and retrieval-augmented generation (RAG)-based question answering for submarine combat system manuals. A pipeline consisting of document embedding, a vector database, and fine-tuning was implemented, and the performance was comparatively evaluated using a benchmark dataset composed of 100 multiple-choice and 100 open-ended questions. The experimental results indicate that applying RAG and fine-tuning improves response accuracy and contextual relevance compared with the baseline model and confirm the applicability of the proposed approach to submarine combat systems.
