최근 스마트폰의 폭발적인 보급, IoT와 클라우드 컴퓨팅 기술의 고도화, 그리고 IoT 디바이스의 보편화로 대용량 스트리밍 센싱데이터가 출현하였다. 또한 이를 기반으로 데이터의 공유와 매쉬업 통해 새로운 데이터의 가치를 창출하기 위한 요구사항의 증대로 대용량 스트리밍 센싱데이터 환경에서 시맨틱웹 기술과의 접목에 관한 연구가 활발히 진행되고 있다. 하지만 데이터의 대용량성・스트리밍성으로 인해 새로운 지식을 도출하기 위한 지식 추론분야에서 많은 이슈들에 직면하고 있다. 이러한 배경하에, 본 논문에서는 IoT 환경에서 발생하는 대용량 스트리밍 센싱데이터를 시맨틱웹 기술로 처리하여 서비스하기 위해 RDFS 규칙기반 병렬추론 기법을 제시한다. 제안된 기법에서는 기존의 규칙추론 알고리즘인 Rete 알고리즘을 하둡프레임워크 맵리듀스를 통해 병렬로 수행하고, 공용 스토리지로서 하둡 데이터베이스인 HBase를 사용하여 데이터를 공유한다. 이를 위한 시스템을 구현하고, 대용량 스트리밍 센싱데이터인 기상청 AWS 관측데이터를 이용하여 제시된 기법에 대한 성능평가를 진행하고, 이를 입증한다.
