Research on restaurant recommender systems has been proposed due to the development of the food service industry and the increasing demand for restaurants. Existing restaurant recommendation studies extracted consumer preference information through quantitative information or online review sensitivity analysis, but there is a limitation that it cannot reflect consumer semantic preference information. In addition, there is a lack of recommendation research that reflects the detailed attributes of restaurants. To solve this problem, this study proposed a model that can learn the interaction between consumer preferences and restaurant attributes by applying deep learning techniques. First, the convolutional neural network was applied to online reviews to extract semantic preference information from consumers, and embedded techniques were applied to restaurant information to extract detailed attributes of restaurants. Finally, the interaction between consumer preference and restaurant attributes was learned through the element-wise products to predict the consumer preference rating. Experiments using an online review of Yelp.com to evaluate the performance of the proposed model in this study confirmed that the proposed model in this study showed excellent recommendation performance. By proposing a customized restaurant recommendation system using big data from the restaurant industry, this study expects to provide various academic and practical implications.

웹 기술의 발전으로 협업 가상환경에서 사용자들끼리 실시간으로 상호작용할 수 있는 온라인 커뮤니티가 크게 활성화되고 있다. 커뮤니티 사용자들은 가상공간에서 자신의 과업 수행 뿐만 아니라 복수의 다른 사용자들과도 공통의 관심사나 정보를 상호 교환하고 공유할 수 있는 기회를 찾고 있다. 특히 온라인 커뮤니티에서는 웹으로 제공하는 보고서에 대해 사용자의 정보인지과정을 향상시키기 위해 아바타를 이용하는 경우가 증가하고 있다. 본 연구는 웹상의 보고서 복잡성에 따라 아바타의 유형이 소비자의 정보인지과정에 어떠한 영향을 미치는지 실증분석을 통해 검증하였다. 첫째, 웹상에서 아바타를 이용하여 보고서를 제공하는 경우에 직무형 아바타가 재미형 아바타보다 사용자의 정보인지과정에 있어서 정보신뢰에 유의한 영향을 미치는 것으로 나타났다. 그러나 정보품질과 정보만족은 유의한 영향을 미치지 않았다. 둘째, 웹상에 제공되는 보고서에 대한 소비자의 정보인지과정이 아바타의 유형과 보고서의 복잡성간의 상호작용에 의해 유의한 영향을 받지 않는 것으로 나타났다. 셋째, 웹상에 제공되는 보고서의 복잡성 정도에 따라서 소비자의 정보인지 과정에 차이가 나는지에 대한 분석결과는 정보품질과 정보만족에는 차이가 나는 것으로 나타났다. 즉, 복잡성이 낮은 보고서가 복잡성이 높은 보고서보다 정보 품질과 정보 만족에 더 많은 영향을 미치는 것으로 나타났다. 그러나 정보신뢰는 유의한 영향을 받지 않는 것으로 나타났다.

This study introduces e-purchase potential matrix and examines whether the Web purchase suitability mediates the effects of the internet consumer characteristics such as diversification, innovativeness, self-realization, and informativity on online purchase intention through an empirical analysis. Specifically, this study investigates whether the Internet consumer characteristics affect the two dimensions differently. The results show that the Web purchase suitability partially mediates the effects of the internet consumer characteristics on online purchase intention.

The purpose of this research was to analyze the effect of consumer innovativeness on the evaluation of online fashion advertisement sustainability and on purchase intentions of advertising products. Online survey have been conducted of 573 people who had experience of online advertisements. The data collected from the surveys were analyzed by the factor analysis, the t-test and the multiple regression analysis. the results are as follows: Firstly, it has been identified that the concept of sustainability of online fashion advertisement consists of four sub-elements of the objectivity of advertisement expressions, the non-harmfulness of advertisement expressions, the protection of personal information, and the non-infringement of web use. Secondly, the group that has a higher consumer innovativeness shows a significantly higher experience of online advertisements as well as more many internet use hours than those who have a lower consumer innovativeness. In addition, comparing with the group that shows lower consumer innovativeness, the group who has higher consumer innovativeness shows a significantly higher recognition of the protection of personal information, the non-infringement of web use and the objectiveness of advertisement expressions among the sub-elements of online fashion advertisement. Lastly, the objectiveness of advertisement expressions and the non-infringement of web use significantly affect the intentions of the group that has high consumer innovativeness to purchase advertised products, and the purchase intentions of those who have low consumer innovativeness are significantly affected by the objectiveness of advertisement expressions and the protection of personal information.

This article examines how consumers in online environments depend on brand in making purchase decisions by product types. Previous research explains that the characteristics of online environments decrease the dependence on brand due to inexpensive search costs and affluent information quantity. But it is likely that in online environment, the dependence on brand will be differentiated by product types. We found that in search product, the availability of information decreased consumer's uncertainty, which, in turn, increased the dependence of brand. However, in experience products, the weakness of multi-sensory increased consumer's uncertainty, which resulted in the increase of the dependence of brand.

The research conducted here focuses on the definition and organization of information privacy concerns in e-commerce process. Based on the identified concept of information privacy concerns(IPC), this study additionally explores the interrelationships among consumers' individual characteristics(self-efficacy, digital literacy, customer alienation), customer satisfaction and intention to buy. Through empirical model analysis, this study found that self-efficacy and digital literacy affect negatively IPC, while customer alienation has an positive effect on IPC. IPC affects positively customer satisfaction. Academically, this study extends IPC to an empirical research model by identifying the conceptualization and organization of IPC. Moreover, practically, e-commerce providers can develop how to relieve IPC of online consumers.

A counterfeit product is a product that pretends to be a genuine product by pretending to be false. It can also be called a counterfeit product. This study attempts to investigate how such illegal floods of counterfeit goods affect online shopping consumers. In addition, the accessibility of various product reviews on the internet is increasing, and the product reviews are divided into positive and negative reviews, affecting the information that the customer has already, and the influence of the information acceptance on the purchase intention depending on the product involvement Respectively. Therefore, the focus of this study was to examine whether the information presentation about counterfeit products affects consumers' purchase intention, review direction (positive / negative), and involvement (high / low) control the information about counterfeit products. Therefore, this study has shown that it provides a marketing strategy to increase the intention to purchase products and products in online companies and stores in a situation where information about counterfeits is exposed to online consumers in China market.
