Abstract
본 논문에서는 WiseQA 시스템에서 정답유형을 인식하기 위한 하이브리드 방법을 제안한다. 정답유형은 어휘정답유형과 의미정답유형으로 구분된다. 본 논문은 어휘정답유형 인식을 위해서 질문초점에 기반한 규칙모델과 순차적 레이블링에 기반한 기계학습모델을 제안한다.의미정답유형 인식을 위해 다중클래스 분류에 기반한 기계학습모델과 어휘정답유형을 이용한 필터링 규칙을 소개한다. 어휘정답유형 인식성능은 F1-score 82.47%이고, 의미정답유형 인식성능은 정확률 77.13%이다. 어휘정답유형 인식성능은 IBM 왓슨과 비교하여, 정확률은1.0% 저조하고, 재현율은 7.4% 높다.
