Abstract

Since users who search maps conduct their searching using the name they already know or is commonly called rather than formal name of a specific place, they tend to fail to find their destination. In addition, in typical web map service in terms of spatial searching of map. Location information of unintended place can be provided because when spatial searching is conducted with the vocabulary 'nearby' and 'in the vicinity', location exceeding 2 km from the current location is searched altogether as well. In this research, spatial range that human can perceive is calculated by extracting POI date with the usage of twitter data of SNS, constructing spatial relations with existing POI, which is already constructed. As a result, various place names acquired could be utilized as different names of existing POI data and it is expected that new POI data would contribute to select places for constructing POI data by utilizing to recognize places having lots of POI variation. Besides, we also expect efficient spatial searching be conducted using diverse spatial vocabulary which can be used in spatial searching and spatial range that human can perceive.

지도를 검색하는 사용자는 특정 장소에 대한 정식 명칭보다는 자신이 알고 있는 명칭이나 일반적으로 불리어지는 명칭을 이용해 검색을 수행하기 때문에 원하는 장소를 찾는데 빈번히 실패하게 된다. 또한 지도의 공간검색에 있어서 대표적인 웹 지도 서비스에서는 '근처'와 '주변'이라는 공간어휘를 가지고 공간상 인접 장소를 탐색하는데 2km 이상 떨어진 장소까지 검색되어 원하지 않는 위치의 장소 정보를 제공하기도 한다. 본 연구에서는 SNS 중 트위터를 이용하여 POI 데이터를 추출하고, 기구축되어 있는 기존POI로부터 공간관계를 구축해 사람이 인지할 수 있는 공간범위를 산정하였다. 그 결과, 다양한 장소 명칭을 획득하여 기존 POI 데이터의 다른 이름의 명칭으로 활용할 수 있었고, 기존에 없는 새로운 POI 데이터는 POI 변화가 많은 지역을 파악하는데 활용하여 POI 데이터 구축을 위한 지역선정에 도움이 될 것으로 기대된다. 또한 공간검색에 사용될 수 있는 다양한 공간어휘와 사람이 인지할 수 있는 공간범위를 이용해 보다 효율적인 공간검색을 수행할 수 있을 것으로 기대된다.
