As personalized customer services create a society that emphasizes the personality of an individual, the number of product reviews and quantity of user data generated by users on the internet in mobile shopping apps and sites are increasing. Such product review data are classified as unstructured data. Unstructured data have the potential to be transformed into information that companies and users can employ, using appropriate processing and analyses. However, existing systems do not reflect the detailed information they collect, such as user characteristics, purchase preference, or purchase priority while analyzing review data. Thus, it is challenging to provide customized recommendations for various users. Therefore, in this study, we have developed a product recommendation system that takes into account the user's priority, which they select, when searching for and purchasing a product. The recommendation system then displays the results to the user by processing and analyzing their preferences. Since the user's preference is considered, the user can obtain results that are more relevant.

This empirical study explored characteristics that affect the usefulness of online reviews, in the China e-commerce platform, and implemented multiple regressions to find factors that significantly influence on product sales, ultimately. Till now, prior studies have continuously revealed what factor affects usefulness of online review or product sales, only in respective terms. The point of our study is that we built two-level regression models, thereby being able to comprehensively analyze these two different targets. Before plunging into running regressions, we carefully collected 192,764 online review data for 200 products extracted from the Jingdong, the second biggest e-commerce platform in China. Also, we gathered "review sentimental scores" variable from each review and used that one as a core variable in our regression model, thus we were able to implement both quantitative and qualitative research. The evidences from the two-level regression models showed that the extent to which a product is experience good positively affects both usefulness of a review and product sales, again the usefulness of a review contributes to product sales in sequence. Also, the property of experience good has interaction effect on both for two-level regression models. Our main findings highlight the importance of role of online review to business performance of e-commerce firms.

The increase use of smartphones has paved the way for quick dissemination of online information. This has a huge influence on consumers' purchase decision making and the formation of a company's image. As such, this study focuses on product review from mobile beauty applications(apps); in particular, the perceived information authenticity. The purpose is as follows. First, to examine if there is any difference in perceived information authenticity based on the types of product review. Second, to analyze how perceived information authenticity influences brand attitude, purchase intention, and electronic word of mouth(e-WOM) intention. The study targets consumers in their 20s and 30s who have experience buying a product via a mobile beauty app. Three hundred responses are analyzed using SPSS 21.0 and AMOS 18.0. The results reveal that, first of all, consumers derive higher perceived information authenticity from a multi-facet review rather than a double-facet review. Second, among the traits of perceived information authenticity, only a brand's perceived reliability has a significant influence on brand attitude. Third, this brand attitude has a positive influence on purchase intention and e-WOM intention. In conclusion, these findings can serve as an important discussion point for companies developing a mobile beauty app, drawing attention to perceived information authenticity, based on the types of product review.

Expanding product variety and high customer service provision place an enormous burden on demand forecasting and the matching of supply with demand in a supply chain. Postponement of product differentiation has been found to be powerful means to improve supply chain performance in the presence of increasing product variety. Delaying the point of product differentiation implies that the process would not commit the work-in-process into a particular finished product until a later point. This paper reviews the recent analytical models that quantify the value of delayed product differentiation. We conclude the literature review by summarizing and synthesizing the economic evaluation of the postponement and outline directions for future research.

Purpose The impact of online reviews is widely acknowledged, with extensive research focused on text-based reviews. However, there's a lack of research regarding reviews in video format. To address this gap, this study aims to explore the connection between company-sponsored product review videos and the extent of directive speech within them. This article analyzed viewer sentiments expressed in video comments based on the level of directive speech used by the presenter. Design/methodology/approach This study involved analyzing speech acts in review videos based on sponsorship and examining consumer reactions through sentiment analysis of comments. We used Speech Act theory to perform the analysis. Findings YouTubers who receive company sponsorship for review videos tend to employ more directive speech. Furthermore, this increased use of directive speech is associated with a higher occurrence of negative consumer comments. This study's outcomes are valuable for the realm of user-generated content and natural language processing, offering practical insights for YouTube marketing strategies.

e비즈니스가 활발히 이루어지면서 소비자들은 온라인 쇼핑몰올 통해 수많은 상품을 접할 수 있게 되었고, 상품구매 시 다른 사람들의 리뷰를 참고하게 되었다. 하지만, 리뷰의 수도 많아짐에 따라 소비자가 모든 리뷰들을 살펴보기가 힘들다는 문제점이 대두되었으며 이를 해결하기 위해서 리뷰의 상품에 대한 평가를 요약하고 성향을 파악하는 오피니언 마이닝 연구가 나타나게 되었다. 본 논문에서는 상품리뷰를 대상으로 오피니언 마이닝을 수행하는 경우 어휘의 의견 성향을 파악할 때, 문맥정보를 활용하여 기존의 의견분류방법 보다 좀 더 정확한 의견 판단이 가능한 방법에 대해 다루고 있다. 이를 위해, 어휘가 사용될 때의 문맥정보를 정의하고 이를 의견분류에 적용하는 방법을 제안하였으며, 실험을 통하여 기존 연구 보다 상황별 알맞은 의견분류가 가능함을 보였다. 또한 수작업으로 말뭉치의 핵심 어휘들을 정의했던 기존 연구들에서의 방식에서 벗어나, 리뷰본문과 리뷰점수를 활용하여 자동으로 상황에 맞는 말뭉치를 구축하는 방법도 제안하였다. 이를 통해 상품리뷰에 나타난 어휘들의 문맥에 맞는 의미 성향을 정확하고 쉽게 판별해 낼 수 있게 되었다.

This study aims to explore the influence of product popularity signals on purchase intention in China's open market, with a focus on understanding the interaction effect of fashion product types. The popularity signals were measured through sales volume and review volume. For the experiment, a 2 (sales volume: high vs low) × 2 (review volume: high vs low) × 2 (fashion product type: trend vs basic) factorial design was employed. The findings of this study are summarized as follows. First, sales volume and review volume, as signals of the popularity of fashion products, did not appear to have a direct effect on purchase intention. Second, the impact of fashion product popularity on purchase intention was found to be contingent on the type of fashion product. When purchasing trendy fashion products, purchase intention was found to be higher under low popularity conditions compared to high popularity conditions. When purchasing basic fashion products, purchase intention was found to be higher under high popularity conditions compared to low popularity conditions. These findings contribute valuable insights for developing marketing strategies that leverage popularity signals for fashion products in China's open markets. Furthermore, the study improves understanding of online fashion product purchasing behavior among Chinese consumers.

상품 또는 상점에 대해 거짓된 후기를 남기는 악의적인 사용자가 증가함에 따라 사용자에게 신뢰성 있는 정보를 제공하는 데 어려움을 겪고 있다. 거짓된 후기는 리뷰 스팸이라고 불리는데, 제품을 홍보하거나, 평판을 훼손하기 위해 작성된다. 이는 제품의 판매량에 직접 영향을 미치기 때문에 이러한 리뷰 스팸을 탐지할 필요가 있다. 국내 쇼핑 사이트에서도 리뷰 스팸은 흔히 접할 수 있으나, 기존 연구에서 제안된 방법은 모두 외국 사이트에서만 평가되었다. 따라서, 본 논문에서는 리뷰 스팸을 탐지하는 기존 방법의 소개와 더불어 네이버 쇼핑의 리뷰 특성을 파악하고, 리뷰 스팸을 탐지하는 여러 가지 방법을 네이버 쇼핑에 적용하여 성능을 평가하였다.
