초록

본 연구는 건강식 레스토랑의 소비자 리뷰를 분석하여 고객이 인식하는 건강성 요인을 파악하고자 하였다. 이전 연구 들은 주로 식품 제품의 건강성에 초점을 맞춘 반면 레스토랑의 관점에서 온라인 리뷰 분석을 통한 건강성 연구는 제한적 이다. 이를 위해 텍스트 마이닝 방법론 중 동시 출현 네트워크 분석과 LDA 토픽 모델링을 사용하여 대규모 온라인 리뷰 데이터에서 건강식 레스토랑에 대한 소비자의 건강 관련 인식과 선호도를 조사하였다. 분석 결과, 소비자들은 건강식 레 스토랑을 선택할 때 맛, 식재료의 카테고리, 신선도, 가격, 영양 성분, 건강 옵션, 메뉴의 다양성 등 다양한 건강 관련 요 소를 중시하며 이러한 요소들은 레스토랑의 평가 및 선택에 중대한 영향을 미치는 것으로 나타났다. 특히 건강식 레스토 랑에서 제공되는 음식의 맛이 건강성과 밀접하게 연결되어 있음을 발견하였고 재료에서 느껴지는 건강한 맛에 대한 중 요성이 강조되었다. 결론적으로 본 연구는 건강한 레스토랑이 소비자의 건강성 인식을 어떻게 반영하고 충족시킬 수 있는지에 대한 실질적인 통찰을 제공하며, 식품 및 외식 산업의 건강 트렌드에 대응하는 전략적 방향을 제시한다.

Abstract

This study aimed to identify the factors contributing to perceived healthiness by analyzing consumer reviews of healthy restaurants. While previous studies have primarily focused on the healthiness of food products, comprehensive research from the perspective of restaurants through online review analysis is limited. To achieve this, co-occurrence network analysis and LDA topic modeling, methods of text mining, were used to investigate consumers’ health-related perceptions and preferences for healthy restaurants based on a large dataset of online reviews. The analysis revealed that consumers emphasize various health-related factors such as taste, ingredient categories, freshness, price, nutritional content, healthy options, and menu diversity when choosing healthy restaurants. These factors significantly influence the evaluation and selection of restaurants. Notably, it was found that the taste of food offered in healthy restaurants is closely linked to the perception of healthiness, highlighting the importance of a healthy taste derived from ingredients. In conclusion, this study provides practical insights into how healthy restaurants can reflect and meet consumers’ health perceptions and suggests strategic directions for the food and dining industry to respond to health trends.
