연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

본 연구의 목적은 인공지능의 딥러닝을 활용하여 소셜미디어에서 공유되는 도시공원 이용자 활동사진을 분류하는 기초 모델을 만드는 것이다. 소셜미디어 데이터는 네이버 검색을 통해 수집된 도시공원 관련 사진들을 수집하여 분류모델에 활용하였다. 도시공원 특성 평가에 활용할 수 있는 지표인 자연성(naturalness), 잠재적 매력성(potential attraction), 활동(activity)을 기반으로 최종 21개의 분류 항목체계를 만들고, 항목별로 네이버에서 공유되는 실제 도시공원 사진을 수집하여 주석이 달린 데이터 세트를 구축했다. 수집한 사진 데이터 세트에 대해 커스텀(cuntom) CNN 모델과 사전 훈련된 CNN의 전이학습 모델을 설계하고 분석하였다. 연구결과, 가장 우수한 성능을 보였던 Xception 전이학습 모델이 최종적으로 도시공원 이용자 활동 이미지 분류모델로 선정되었으며, 그 외 다양한 평가 지표를 통해 모델을 평가했다. 본 연구는 소셜미디어에 공유되는 이용자 사진을 활용하여 도시공원 특성을 평가할 수 있는 지표로서 AI를 구축한 것에 의의가 있다. 딥러닝을 활용한 분류모델은 수동분류에 대한 한계를 보완하고, 대량의 도시공원 사진을 효율적으로 분류할 수 있어서 향후 도시공원의 모니터링 및 관리에 활용할 수 있는 유용한 방법이라고 할 수 있다.

Abstract ▼ AI-Helper 아이콘AI-Helper

This study aims to create a basic model for classifying the activity photos that urban park users shared on social media using Deep Learning through Artificial Intelligence. Regarding the social media data, photos related to urban parks were collected through a Naver search, were collected, and used...
