이 연구는 토픽모델링을 적용하여 뉴스기사에 따른 태권도 동향을 연도별로 분석하는 것에 목적이 있다. 언론보도를 통한 태권도 동향을 살펴보기 위해 한국언론재단의 빅카인즈를 통해 뉴스기사와 태권도 전문 언론에 대한 기사를 수집하였다. 검색기간은 2000년 이전, 2001년~2010년, 2011년~2020년 3개의 구간으로 구분하여 검색하여 총 12,124개를 연구자료로 선정하였다. 토픽분석을 위해 전처리 과정을 거쳤으며, LDA 알고리즘을 활용하여 토픽분석을 수행하였다. 이때 모든분석은 python 3을 적용하였다. 그 결과 첫째, 연도별에 따른 언론기사 주제를 분석한 결과 2000년이전 1위는 '세계'. 2위는 '남북', 3위는 '올림픽'으로 나타났으며, 2001년~2010년 1위는 '세계', 2위는 '협회', 3위는 '세계태권도연맹'으로 조사되었다. 2011년~2020년 1위는 '세계', 2위는 '시범', 3위는 '국기원'으로 나타났다. 둘째, 2000년이전 뉴스기사를 토픽모델링으로 분석한 결과 토픽은 2가지로 구분되었다. 구체적으로 Topic 1은 '남·북 체육교류', Topic 2는 '올림픽 시범종목 채택'으로 선정되었다. 셋째, 2001년~2010년 뉴스기사를 토픽모델링으로 분석한 결과 토픽은 3가지로 선정되었다. Topic 1은 '태권도 시범공연 및 비리', Topic 2는 '무주태권도공원 조성', Topic 3은 '세계태권도축제'로 선정되었다. 넷째, 2011년~2020년 뉴스기사를 토픽모델링으로 분석한 결과 토픽은 3가지로 선정되었다. Topic 1은 '2018 평창동계올림픽 성공 개최', Topic 2는 '남북 태권도 합동시범공연 ', Topic 3은 '2017 무주세계태권도선수권대회'로 선정되었다.

Abstract ▼ AI-Helper

This study aims to analyze Taekwondo trends according to news articles by year by applying topic modeling. In order to examine the Taekwondo trend through media reports, articles including news articles and Taekwondo specialized media articles were collected through Big Kinds of the Korea Press Foundation. The search period was divided into three sections: before 2000, 2001~2010, and 2011~2020. A total of 12,124 items were selected as research data. For topic analysis, pre-processing was performed, and topic analysis was performed using the LDA algorithm. In this case, python 3 was applied for all analysis. First, as a result of analyzing the topics of media articles by year, 'World' was the most common keyword before 2000. 'South and North Korea' was next common and 'Olympic' was the third commonest topic. From 2001 to 2010, 'World' was the most common topic, followed by 'Association' and 'World Taekwondo'. From 2011 to 2020, 'World', 'Demonstration', and 'Kukkiwon' was the most common topic in that order. Second, as a result of analyzing news articles before 2000 by topic modeling, topics were divided into two categories. Specifically, Topic 1 was selected as 'South-North Korea sports exchange' and Topic 2 was selected as 'Adoption of Olympic demonstration events'. Third, as a result of analyzing news articles from 2001 to 2010 by topic modeling, three topics were selected. Topic 1 was selected as 'Taekwondo Demonstration Performance and Corruption', Topic 2 was selected as 'Muju Taekwondo Park Creation', and Topic 3 was selected as 'World Taekwondo Festival'. Fourth, as a result of analyzing news articles from 2011 to 2020 by topic modeling, three topics were selected. Topic 1 was selected as 'Successful Hosting of the 2018 Pyeongchang Winter Olympics', Topic 2 was selected as 'North-South Korea Taekwondo Joint Demonstration Performance', and Topic 3 was selected as '2017 Muju World Taekwondo Championships'.
