본 연구의 목적은 외식산업과 관련된 연구동향에 대한 분석을 통해 외식산업 발전 방안을 찾고자 하는 것이다. 첫째, food, service, restaurant, customer, intention, consumer, relationship, industry, satisfaction, company 등과 관련된 키워드가 빈번하게 이용된 것을 알 수 있었다. 둘째, food를 중심으로 service, restaurant, customer, quality 등이 연결되어 있었으며 management와 performance, sns와 type이 별도로 연결되어 있으며, brand, life, trust, menu, franchaise, risk 등이 별도로 연구되는 것으로 나타났다. 셋째, consultant, justice, blog, honbob, shop, globalization, leisure, coaching, complain, dakgalbi, label 등이 TF-IDF에 출현한 것을 볼 때 외식과 관련된 연구가 다양한 산업 전반에 걸쳐 관련된 연구들도 포함되어 있음을 알 수 있다. 넷째, 외식산업 연구는 구매행동, 프랜차이즈, 기업전략, 종사자, 웰빙, 관광, 선택속성, 환경 등의 분야에서 연구가 진행되고 있음을 확인하였다.

The purpose of this study is to find a way to develop the food service industry through analysis of research trends related to the restaurant industry. In this study, through detailed search on RISS, 269 papers related to 'food service' with English abstracts were analyzed using R package to analyze keyword frequency, word clouding, keyword network analysis, LDA topic modeling, and TF, TF.-IDF verification was performed. The analysis results are as follows. First, as a result of keyword frequency analysis and word clouding, it was found that keywords related to food, service, restaurant, customer, intention, consumer, relationship, industry, satisfaction, company, etc. were frequently used. Second, as a result of word network analysis, service, restaurant, customer, and quality are connected centering on food. Management and performance, sns and type are separately connected. Brand, life, trust, menu, franchise, risk, etc. are being studied separately. Third, as a result of TF and TF-IDF analysis, the words in TF-IDF (eg, consultant, justice, blog, honbob, shop, globalization, leisure, coaching, complain, dakgalbi, label) in TF-IDF were not found in studies related to food service. It can be seen that related studies across various industries are also included. Finally, as a result of LDA topic modeling, the appropriate number of topics is 8, and each characteristic is defined as purchasing behavior, franchise, corporate strategy, workers, well-being, tourism, selection attributes, and environment. Topics 1 to 4 account for 74.2% of the total IDM.
