Online reviews offer valuable information to businesses by reflecting consumer experiences about their products and services. Two important aspects of online reviews are first, the topics consumers choose to address and second, the sentiments expressed in their reviews. Building upon previous literature that shows online reviews are context-dependent, we examine the impact of topic distribution on review sentiment in South Korea and the U.S. during pre-and post-pandemic periods. After performing topic modeling on Airbnb app review data, we measure the contribution of each topic on review sentiment using SHAP values. Our results indicate variations in topic distribution trends between 2018 and 2021. Also, the order and magnitude of topics' impact on review sentiment change between pre-and post-pandemic periods for both countries. This study can help businesses to understand how topics and sentiments associated with their products and services changed after pandemic, and also help them identify areas of improvement.

Online reviews offer valuable information to businesses by reflecting consumer experiences about their products and services. Two crucial aspects of online reviews are the topics consumers choose to address, and the sentiments expressed in their reviews. Building upon previous literature that shows online reviews are context-dependent, we employ the Expectation-Confirmation Theory (ECT) to examine the impact of topic distribution on review sentiment in South Korea and the U.S. during pre- and post-pandemic periods. After applying a topic modeling to Airbnb app review data, we measure the contribution of each topic on review sentiment using SHAP values. Our results indicate variations in topic distribution trends between 2018 and 2021. In addition, the order and magnitude of topics' impact on review sentiment change between pre- and post-pandemic periods for both countries. This study can help businesses understand how topics and sentiments associated with their products and services changed after the pandemic and thus identify areas of improvement.

Purpose - The purpose of this study to explore factors consumers prioritize when purchasing seafood online. The originality of the study lies on adopting AHP-based approach in analyzing prioritized purchasing factors of seafood online. Design/methodology/approach - A survey was conducted targeting Korean consumers who have purchased seafood online. AHP method was applied to rank factors consumers prioritize before making decision. Findings - First, product's factor ranked first among other high level factors including delivery service, seller, online platform. Second, sanitation, taste, country of origin ranked first, second, third respectively, within product's factors. Third, safe delivery, timeliness, information accuracy ranked first, second, third respectively, within delivery factors. Fourth, consumer reviews, consumer response ability, promotion ranked first, second, third within seller factors. Fifth, Personal information management system, credibility, user-friendliness ranked first, second, third, within online platform factors. Research implications or Originality - To activate seafood online market, it is crucial to assure consumers that the seafood is well managed in a sanitary way from the production site to table. Existing government programs such as seafood traceability system, HACCP, and cold-chain infrastructure needs improvement. Due to highly perishable characteristic of seafood, delivery factors matter when purchasing online. Online platforms needs to continue to improve delivery service. Seafood products are mostly not branded and without objective information about their properties. Creating quality classification and seafood brands are likely to help consumers chose seafood online.

소비자행동과 관련된 기존 문헌은 소비자의 위험인식이 제품 관여도에 의해 중요한 영향을 받는다는 점을 제시하는 반면, 소비자가 요구하는 상인의 신뢰수준이나 소비자의 제품구매 상인의 선택이 관여도에 의해 어떻게 영향을 받는지에 대해서는 연구가 부족하다. 본 연구는 제품 관여도가 요구 신뢰수준 및 온라인 상인 선택에 미치는 영향을 조명하는데 목적이 있다. 이 목적을 달성하기 위해, 제품 관여도, 요구 신뢰수준, 온라인 상인 선택 등 개념들 간의 관계를 나타내는 연구모델을 개발하고, 연구모델을 근거로 세 개의 가설 및 한 개의 명제를 설정하였다. 그리고 연구모델을 테스트할 목적으로 230명의 대학생들을 대상으로 한 설문조사를 수행하였으며 수집된 데이터를 이용해 실증분석을 실시하였다. 연구결과를 통해, 고관여 제품이 저관여 제품에 비해 소비자가 요구하는 신뢰수준이 더 높고, 고관여 제품을 구매하는 소비자는 온라인 쇼핑몰을 선호하는 반면 저관여 제품을 구매하는 소비자는 이마켓플레이스를 선호하는 것으로 나타났다. 이러한 연구결과에 기초하여 실무자 및 연구자를 위한 시사점을 제시하였다.

온라인 마켓에서 소비자는 다양한 상품을 접하고 이에 대한 의견을 자유롭게 기술한다. 소비자의 상품 리뷰가 다른 소비자와 온라인 마켓의 성공에 큰 영향을 주는 만큼 온라인 마켓은 판매 상품에 대한 소비자의 감성을 정확하게 분석할 필요가 있다. 데이터 분석 기법 중 하나인 텍스트 마이닝은 상품에 대한 소비자 리뷰를 분석하여 상품을 효율적으로 관리할 수 있게 해준다. 선행 연구들은 데이터 도메인과 사이즈에 따라 분석 결과의 정확도가 다르게 나타남에도 불구하고 특정 도메인과 2만개 미만의 데이터를 분석해왔다. 또한, 분석의 정확도를 향상 시킬 수 있는 추가 요인에 대한 연구는 거의 수행하지 않았다. 본 연구는 앙상블 기법을 활용하여 기존 연구에서 주로 다루지 않은 음식 상품 도메인의 72,530개 리뷰 데이터를 분석하였다. 또한, 분석 정확도 향상과 관련하여 요약 리뷰의 영향력을 살펴보았다. 연구 결과, 본 연구는 기존 연구와 다르게 부스팅 앙상블 기법이 가장 높은 분석 정확도를 보인다는 사실을 발견하였다. 또한, 요약 리뷰는 분석의 정확도 향상에 기여하는 것으로 나타났다.

This study examines customer reviews from online stores of Korean vegan fashion brands to determine the qualities that customers value in vegan fashion items. For this purpose, we conducted a case study of online reviews-2,285 reviews were collected and analyzed. The results are as follows: The clothing evaluation criteria for vegan fashion products can be divided into four categories: aesthetics, material characteristics, affordability, and characteristics. This suggests that evaluation standards for vegan fashion items operate at multiple levels. The animal welfare aspect of the product was the most important factor, followed closely by how well the clothes fit. High-quality vegan materials and the use of recycled materials that are environmentally friendly were emphasized. The findings of this study suggest that even for vegan products, stylistic features remain an essential component of fashion items. To understand the main aspects of clothing evaluation criteria in the current vegan fashion market, this study differs from other studies in that it examined online reviews of vegan fashion brands. This comprehensive analysis contributes to a deeper understanding of customer preferences and highlights the importance of ethical considerations alongside style in the evaluation of vegan fashion items, providing valuable insights for the industry. Moving forward, this study is significant in suggesting that vegan fashion brands should develop their products as well as their brands, capitalizing on the demand for ethically conscious and stylish options.

This study examined: 1) the effects of fashion luxury product price discounts in social commerce on perceived benefit and purchase intention, and 2) differences in such effects by social commerce trust, brand and design preferences for luxury products as well as social commerce and online luxury product purchase experiences. Three discount rates representing high, mid, and low for a luxury product sold in social commerce were manipulated and tested on female consumers and 486 online responses were analyzed. The results revealed that the price discount affected perceived benefit but did not affect purchase intention. Benefits were highly perceived at high and mid discount rates compared to the low rate. Social commerce trust, brand preference, and design preference affected perceived benefit and purchase intention, but the interaction effect with price discount was observed only in the design preference to perceived benefit. The purchase experience of online luxury products also affected purchase intention. Implications from the results were also discussed.

In this study, five women's fashion shopping mall companies were selected as the subjects based on the number of searches per month for analyzing website design of online shopping mall for women in their twenties. Design characteristics are divided into three aspects such as structural, visual, and customer service, and the results are as follow. First, from the structural perspective, the main navigation area and global navigation area of most shopping malls are arranged at the top center, and below them, the main image, the banner area, and the content area are arranged in order. Looking at the visual aspect, the logo is mostly written in a black text, the colors used on the main page were only one or two colors such as pink-based, gray-based, and red. Finally, from the customer service aspect, most shopping malls were encouraging buyers to place celebrity sponsorship, videos using products, self made products, and best products in the banner area. The results of this study are to present the direction of design for the founders who intend to operate the women' fashion shopping mall in future, and provide basic data for online shopping mall design research.

Purpose - This study investigates how review length and sentiment impact consumers' purchase intentions, using real online reviews as the data source. The study aims to understand how the length and tone of a review affect a potential buyer's decision-making process when considering a purchase. Design/methodology/approach - A 2 (comment length: long vs. short) × 2 (comment sentiment: positive vs. negative) × 2 (product type: practical vs. hedonic) experiment was conducted. Findings - Results indicate that longer reviews have a greater impact on consumers' perceived usefulness compared to short reviews, but do not affect purchase intentions. Review sentiment is found to have a stronger impact than review length, especially for negative sentiment. The study also suggests that consumers pay more attention to reviews of practical products, and that reviews have less influence on hedonic products. Research implications or Originality - The implications of these findings are relevant for both merchants managing reviews and consumers reviewing products.The results of this research could help businesses and marketers optimize their online review strategies to maximize their impact on consumer behavior.

많은 소비자들의 문제는 온라인을 통해서 구매하고자 하는 제품에 대해 명확한 지식을 획득하기 힘들다는 사실이다. 이에 소비자들은 온라인 사용후기를 통해 먼저 이용해 본 사람들의 의견을 청취하는 행동을 취하는데, 이것은 일종의 온라인 구전으로 일면식도 없는 이들의 구전에 많은 소비자들이 영향을 받고 있다고 말할 수 있다. 결국, 온라인 기업들은 개별 이용자들의 사용후기를 적절히 관리할 필요가 발생하였으며, 이러한 사용후기의 관리를 통해 차후의 이용자들에게 보다 나은 정보와 제품을 제공해 줄 수 있을 것으로 기대하고 있다. 그러나 사용후기는 그 내용의 방향성 및 객관성 여부에 따라 그 영향의 정도가 다르다고 예상해 볼 수 있으므로 이러한 성격을 충분히 고려한 다차원적인 온라인 사용후기의 영향에 대해 이해할 필요가 있다. 연구의 결과, 긍정적이고 객관적인 메시지의 경우 메시지에 대한 태도가 구매, 재방문, 구전의도 등에 가장 큰 영향을 미치는 것으로 나타났으며, 부정적이고 주관적인 메시지의 경우에는 메시지에 대한 태도가 제품태도를 거쳐 구매의도와 구전의도에 유의한 수준에서 영향이 있는 것으로 나타났다. 즉, 메시지의 차원에 따라 제품에 대한 태도, 구매의도, 구전의도, 그리고 재방문의도가 다르게 나타나므로 단순한 사용후기 관리가 아니라 사용후기의 다차원적인 특정을 이해하는 것이 중요하다고 할 수 있다.
