Abstract

Due to the growing popularity of mobile information technology, more people, especially in the general public, have access to computerized geospatial information systems for wayfinding tasks or urban navigation. One of the problems with the current services is that, whether the users are exploring or navigating, whether they are travelers who are totally new to a region or long-term residents who have a fair amount of regional knowledge, the same method is applied and the direction are given in the same way. However, spatial knowledge for a given urban region expands in proportion to residency. Urban navigation is highly dependent on cognitive mental images, which is developed through spatial experience and social communication. Thus, the wayfinding service for a regional community can be highly supported, using well-known regional places. This research is to develop the framework for urban navigation within a regional community. The concept of communal ontology is proposed to aid in urban regional navigation. The experimental work was implemented with case study to collect regional landmarks, develop the ontological model and represent it with formal structure. The final product of this study will provide the geographical information of a region to the other agent and be the fundamental information structure for cognitive urban regional navigation.

최근 정보기술의 발달과 대중화로 인해, 일반인들에게 지리정보의 보급이 확대되었고, 길찾기를 위한 인터넷 지도서비스나 혹은 차량항법장치 등은 공간의사결정에 지리정보시스템을 활용하는 좋은 사례라고 할 수 있다. 기존의 시스템이 제공하는 서비스에서 발견할 수 있는 문제점 중 하나는, 사용자가 그 지역에 처음 방문한 여행자이든 혹은 사용자가 그 지역에 지리를 어느 정도 알고 있는 거주자이든, 동일한 방식의 길찾기 방식이 적용된다는 점이다. 주어진 도시지역에 대한 공간지식은 거주기간에 따라 발달하게 되고, 도시이동은 공간에 대한 경험 속에서 발달된 인지지도에 많은 영향을 받게 되며, 이들의 공간적 지식의 발달은 그들이 속한 사회적 관계에 밀접한 영향을 받게 된다. 따라서 보다 인지적인 길찾기를 위한 서비스를 위해서는, 주어진 지역 내에서 사람들에게 잘 알려진 장소들, 다시 말해, 랜드마크를 통한 위치 인식이 중요한 역할을 하게 된다. 본 연구는 사회적 관계를 공유하는 한 지역 내 커뮤니티의 지역이동에 있어서 발달하는 인지지도를 하나의 공유된 지식으로 보고 이를 활용하는 도시공간이동에 대한 개념적 모델을 제시하였다. 이와 함께, 개념적 모델에 지식공학의 접근방식 중 하나인 온톨로지 방법론의 응용가능성을 살펴보았다. 지역 내 잘 알려진 공유된 랜드마크 지식을 지식모델링 기법의 하나인 온톨로지 방법으로 모델링하여 재사용가능한 지역지식으로 구조화하여 이를 공유 온톨로지라 정의하였다. 사례연구에서는 설문조사와 웹 내용분석의 방식을 통해 랜드마크의 추출하고, 온톨로지 방법론을 통해 사례지역 내 랜드마크 정보를 데이터베이스로 구성하여 활용하는 방안에 대하여 고찰하였다. 본 연구는 기계적 알고리듬으로만 제한된 현재의 GIS 기능을 인지적 모델과 접목을 도모하는데 큰 의미를 갖는다.
