Abstract

Point of interest (POI) of the city is a special place that has what importance to the user. For example, it is such landmark, restaurants, museums, hotels, and theaters. Because of its role in the social and economic life of us, these have attracted a lot of interest in location-based applications such as social networks and online map. However, while it can easily be obtained through the Web, the basic information of POI such as geographic location, another effort is required to obtain detailed information such as Wi-Fi, accepting credit cards, opening hours, romper room and the assessment and evaluation of other users. To solve these problems, a new method for correcting position error is required to link location-based social network service (LBSNS) data and POIs. This paper attempts to propose a position error correction method of POI and LBSNS data to enrich POI information from the vast information that is accumulated in LBSNS. Through this study, we can overcome the limitation of individual POI information via the information fusion method of LBSNS and POI, and we have discovered the possibility to be able to provide additional information which users need. As a result, we expect to be able to collect a variety of POI information quickly.

도시의 POI는 사용자들에게 어떤 중요성을 가지고 있는 특별한 장소이다. 예를 들어 식당, 박물관, 호텔, 극장 그리고 랜드마크 등이다. 이들은 그 역할 때문에 우리의 사회 경제적 생활 속에서 온라인 지도나 소셜 네트워크 등의 위치기반 어플리케이션에서 많은 관심을 받고 있다. 하지만, 지리적 위치 등의 POI에 대한 기본 정보는 웹을 통해서 쉽게 얻을 수 있는 반면, 와이파이 가능 여부, 신용카드 가능 여부, 야외 좌석 여부, 놀이방 운영 여부, 개점 시간, 다른 사용자들의 평가 및 평점 등의 세부 정보를 얻기 위해서는 또 다른 노력이 필요하다. 이러한 문제를 해결하기 위해서는 LBSNS 데이터와 POI 위치의 동일 여부를 판단하여 연결해주는 작업이 필요하다. 이 논문은 LBSNS의 누적되어 있는 방대한 정보로부터 POI의 정보를 더욱 풍부하게 만들기 위한 방법으로 LBSNS 데이터와 POI의 위치 오차해결 방법을 제안하여 두 데이터 집합의 융합 정보를 생성하고자 한다. 본 연구의 POI와 LBSNS의 정보 융합 방법을 통하여 개별 POI 정보의 한계성을 극복하고, 사용자들이 필요로 하는 부가 정보를 제공할 수 있는 가능성을 발견하였다. 이를 통해 POI에 대한 풍부하고 빠른 정보 수집이 가능할 것으로 판단된다.
