본 논문에서는 한국전자통신연구원 언어처리연구팀에서 개발하고 있는 차량용 대화 시스템을 위한 Dialog Act 태깅 코퍼스 구축 방법에 대해 기술하는 것을 목표로 한다. 차량용 태깅 코퍼스 구축 방법은 크게 차량용 대화 코퍼스 수집과 수집된 대화 코퍼스에 Dialog Act를 반자동으로 태깅하는 방법으로 나눌 수 있다. 차량용 대화 코퍼스 수집은 1) 대화플랜 맵 구축, 2) 표준대화 구축, 3) 자유대화 구축, 4) 사용자 발화에 패러프래징 발화 구축의 순으로 구축되었다. Dialog Act 태깅은 수집된 대화코퍼스로부터 슬롯 후보를 추출하여 슬롯 체계를 구축한 후 반자동 슬롯 태깅을 실시하고, 슬롯 태깅 결과와 Dialog Act Type을 조합하여 Dialog Act 태깅 코퍼스를 구축하였다. 이렇게 구축된 Dialog Act 태깅 코퍼스는 차량 공조시스템(에어컨, 히터 등) 및 차량 응급 조치 정보 서비스와 같은 차량용 대화 시스템에 적용 중에 있다.
