Abstract

Recently, semantic trajectories which combine GPS positions and POIs(Point of Interests) become more popular in order to expand location based services. To construct semantic trajectories, the existing algorithms exploit the extent information of POIs described as polygons and find overlapping regions between GPS positions and the extents. However, the algorithms are not applicable in the condition where the extent information is not provided such as in Google Map, Naver Map, OpenStreetMap and most of the open geographic information systems. In this paper, we provide a novel algorithm to construct semantic trajectories only with GPS positions and POI points but without POI extents.

최근 위치기반서비스의 확장을 위해 GPS 위치정보에 관심지점(POI: Point of Interest) 정보를 결합한 시맨틱 궤적(Semantic Trajectory)이 주목받고 있다. 기존 연구의 경우 GPS 궤적과 POI의 면적정보(polygon)가 겹치는 경우를 찾아내어 시맨틱 궤적을 생성하였다. 하지만 구글 지도, 네이버 지도, OpenStreetMap 등과 같은 공개된 지리 정보 시스템에서는 POI의 면적정보를 제공하지 않기 때문에 기존 방법으로는 시맨틱궤적을 생성하지 못하는 문제가 있다. 본 논문에서는 POI의 면적정보가 없는 제한적인 상황에서도 GPS 위치정보와 POI의 좌표값(points)만을 이용하여 시맨틱 궤적을 생성할 수 있는 기법을 제안한다.
