Abstract

This study will examine the social issues and consumer awareness of sharing parking through the method text mining. In this experiment, the topic by keyword was extracted and analyzed using TFIDF (Term frequency inverse document frequency) and LDA (Latent dirichlet allocation) technique. As a result of categorization by topic, citizens' complaints such as local government agreements, parking space negotiations, parking culture improvement, citizen participation, etc., played an important role in implementing shared parking services. The contribution of this study highly differentiated from previous studies that conducted exploratory studies using corporate and regional cases, and can be said to have a high academic contribution. In addition, based on the results obtained by utilizing the LDA analysis in this study, there is a practical contribution that it can be applied or utilized in establishing a sharing economy policy for revitalizing the local economy.

본 연구에서는 공유경제의 다양한 비즈니스 모델 중 공유주차로 범위를 제한하고, 이와 관련된 리뷰를 수집한 후 텍스트마이닝 분석을 통해 공유주차가 갖고 있는 사회적 이슈와 소비자 인식에 대해 살펴보고자 한다. 본 실험에서는 TFIDF (Term frequency inverse document frequency) 기법과 LDA (Latent dirichlet allocation) 기법을 이용하여 키워드별 토픽을 추출하여 분석한 결과 소비자들이 필요로 하거나 원하는 정보들을 파악할 수 있었으며, 토픽으로 분류한 결과 지자체 협약, 주차공간협소, 주차문화개선, 시민참여 등 시민들의 불만과 시민의식이 공유주차 서비스를 시행하는데 중요한 역할을 하고 있다는 것을 확인할 수 있었다. 본 연구는 정성적 연구, 기업 및 지역의 사례를 이용하여 기존의 탐색적 연구를 수행한 선행 연구와는 차별화된 연구로 학술적 기여도가 높다고 할 수 있다. LDA 분석을 본 연구에 활용하여 나타난 결과를 바탕으로 지역경제 활성화를 위한 공유경제 정책 수립에 응용하거나 활용할 수 있다는 실무적 기여도가 있다.
