Abstract

The purpose of this study was to analyze user reviews of running applications using text mining. This study used user reviews of Nike Run Club and Runkeeper in the Google Play Store using the selenium package of python3 as the analysis data, and separated the morphemes by leaving only Korean nouns through the OKT analyzer. After morpheme separation, we created a rankNL dictionary to remove stopwords. To analyze the data, we used TF, TF-IDF and LDA topic modeling in text mining. The results of this study are as follows. First, the keywords 'record', 'app', and 'workout' were identified as the top keywords in the user reviews of Nike Run Club and Runkeeper applications, and there were differences in the rankings of TF and TF-IDF. Second, the LDA topic modeling of Nike Run Club identified the topics of 'basic items', 'additional features', 'errors', and 'location-based data', and the topics of Runkeeper identified the topics of 'errors', 'voice function', 'running data', 'benefits', and 'motivation'. Based on the results, it is recommended that errors and improvements should be made to contribute to the competitiveness of the application.

본 연구의 목적은 텍스트마이닝을 활용하여 러닝 어플리케이션 사용자의 리뷰를 분석하였다. 본 연구는 python3의 selenium 패키지를 이용하여 google playstore의 Nike Run Club, Runkeeper의 사용자 리뷰들을 분석자료로 이용하였으며, okt 분석기를 통해 한글 명사만을 남겨 형태소를 분리하였다. 형태소 분리 후 rankNL 사전을 만들어 불용어(stopword)를 제거하였다. 자료 분석을 위해 텍스트마이닝의 TF(빈도분석), TF-IDF(키워드 빈도-문서 역빈도), LDA 토픽모델링을 통해 분석하였다. 본 연구의 결과는 다음과 같다. 첫째, Nike Run Club, Runkeeper 어플리케이션 사용자 리뷰에서 공통적으로 상위 키워드로 '기록', '앱', '운동'의 키워드가 도출되었으며 TF, TF-IDF의 순위에는 차이가 나타났다. 둘째, Nike Run Club의 LDA 토픽모델링으로 '기본 항목', '추가 기능', '오류 사항', '위치기반데이터'의 토픽이 도출되었고 Runkeeper는 '오류 사항', '음성 기능', '러닝 데이터', '사용 혜택', '사용 동기'의 토픽이 도출되었다. 결과를 통해 제언하면 어플리케이션의 경쟁력 향상을 기여하기 위해 오류 및 개선사항을 보완해야 한다.
