With the continuously increasing volume of e-commerce transactions, it is now popular to buy some products and to evaluate them on the World Wide Web. The product reviews are very useful to customers because they can make better decisions based on the indirect experiences obtainable through these reviews. However, since online shopping malls do not provide ranking results, it is not easy for users to read all the relevant review documents effectively. Product reviews include subjective and emotional opinions. Thus, the review search is different from the general web search in terms of ranking strategy. In this paper, we propose an effective method of ranking the reviews that can reflect user's intention by using opinion mining techniques. The proposed method analyzes product reviews with query words, and sentimental polarity of subjective opinions. Through diverse experiments, we show that our proposed method outperforms conventional ones.

This study aims to identify the factorial constructs of the relational benefits perceived by consumers of outdoor wear brands and their impacts on the consumers' trust in and satisfaction with outdoor wear brands. An online survey was conducted with females and males between the ages of 20 and 50 who have experienced buying outdoor wear brands. A total of 420 responses were analyzed by factor analysis, a reliability test, and multiple regression analysis. The results of this study were as follows: first, the results of factor analysis and the reliability test on the relational benefits perceived by outdoor wear brand purchasers clearly showed conceptual constructs that included informational benefits, social benefits, and psychological benefits. The sub-dimension of perceived relational benefits had significant effects on brand trust and satisfaction. Specifically, respondents revealed that they had higher brand trust if they felt psychologically comfortable, were offered useful information by outdoor wear brands, and had a favorable relationship with salespeople when they bought outdoor wear merchandise. Secondly, influences of perceived relational benefits on brand trust and satisfaction were not shown to differ depending on the congruity between outdoor wear brands and the purchaser's self-image. On the other hand, factors of perceived relational benefits revealed to differently have effects on brand trust and satisfaction depending on respondents' gender and age. Practical implications to understand outdoor wear target customers' relational benefits, self-image congruity and demographic characteristics and to enhance trust and satisfaction with outdoor wear brands are proposed.

Purpose As the smartphone market arrived at its saturation, from world leading information and communications technologies (ICT) businesses to startups, companies are competing to develop innovative wearable device products and suitable contents. Utility, technology, design, price, and various killer contents development targeting every customer's need should be considered for a success in the wearable device market. Design/methodology/approach Prior studies on innovation technology of ICT field have mainly focused on the innovation diffusion theory, expectation confirmation theory, and technology acceptance model, this study suggested the innovation resistance factors of adopting the smart wearable devices based on the innovation resistance model and theory of perceived risk. The model comprises the following two characteristics factors: 1) innovation characteristics which include perceived relative advantages, perceived compatability, perceived complexity, and perceived risk, 2) consumer characteristics which include attitudes towards innovation and existing products (i.e., mobile devices and analog watches). This study developed an extended innovation resistance model to explain the intention to acceptance of wearable devices consumers and collected 284 online survey responses from the non-consumers of the wearable devices. Findings The findings of this study suggest that perceived relative advantage, perceived compatibility, perceived complexity, perceived risk, attitudes towards innovation and attitudes towards existing analog watches affected the innovation resistance which has negative influence on the intention to adoption of wearable devices.

In this paper, we propose a system for efficient customer management by linking the automatic dispenser and bank server computer to smart phone. The proposed background is as follows. The customer management system used by banks has been used by ordinary users. However, with the development of smartphones, the number of online banking users has increased and the number of bank branches has decreased, so that a long waiting time occurs when a bank is directly used offline. In addition, customer inefficiency time loss causes problems in customer service. In this paper, we propose a queue management system based on the number of customers by using the automatic dispenser that is used offline with the smartphone to improve customer service resulting from such a customer management problem.

With the pervasiveness of digital environment and expansion of new media, ICT (Information and Communication Technology) leads the role of consumer to change from a passive customer into an active co-producer. As customer participation in the fashion industry increases, this study attempts to explore the cases of customer participation as a co-producer in fashion industry through analyzing business models of companies, including Threadless, Blank label, Cut on Your Bias, Acustom Apparel, Thinkgivers. The results show that customer participation is mainly facilitated through design participation in fashion industry, with different level of participation and IT as well as different contribution target. Compared to the past, consumer’s preference is reflected through participation before the stage of production. Results indicate three main characteristics of customer participation in fashion industry. First, value co-creations using customer experiences and understanding customer needs are important. Second, active online communication among customers are critical. Third, it is important to ensure customer’s own item. From a customer perspective, participation enables them to purchase their own distinctive product and offers exciting experience and satisfaction over the production processes, and compensation can be used to increase customer participation. On the other hand, companies using customer participation can take advantage of cost reduction in product development, inventory, and marketing. Customer participation, as a win-win strategy for business and consumer, is expected to expand further in the future with the development of ICT.

Recently, the cosmetics industry considers male customers as a consumptive, active customer base who also have purchasing power with their stronger desire for their personal image enhancement. Male-preferred image brands have entered the era of unlimited competition through social media, thus increasing the acquisition of male beauty. Therefore, the information for designing favorable image strategies should be examined. This paper examines male awareness, determined by the degree of appearance management based on four categories (i.e., hair and skin care, makeup, foot and hand care, and plastic surgery). Based on the research, the paper proposes a data service to address the spatial and temporal separation problem between TV CF (the major media for recognizing information) and online $caf{\acute{e}}$/blog the major media for obtaining detailed information.

Similarity computation is very crucial to performance of memory-based collaborative filtering systems. These systems make use of user ratings to recommend products to customers in online commercial sites. For better recommendation, most similar users to the active user need to be selected for their references. There have been numerous similarity measures developed in literature, most of which suffer from data sparsity or cold start problems. This paper intends to extract preference information as much as possible from user ratings to compute more reliable similarity even in a sparse data condition, as compared to previous similarity measures. We propose a new similarity measure which relies not only on user ratings but also on movie genre information provided by the dataset. Performance experiments of the proposed measure and previous relevant measures are conducted to investigate their performance. As a result, it is found that the proposed measure yields better or comparable achievements in terms of major performance metrics.

The number of Chinese tourists visiting Korea has rapidly increased over the last decade. It is important to understand Chinese consumption patterns and shopping behavior because they have become major customers in the Korean fashion market. This study focuses on how Chinese tourists feel while shopping in Korea and how emotions influence their attitude towards purchased products. We examine how planned purchase and unplanned purchase impact shopping emotions and product usage satisfaction. A survey was conducted on 550 women between 20 and 60 years of age who have visited Seoul more than once with an online panel from an international survey firm. Data are analyzed using structural equation modeling by AMOS 20.0. Respondents were asked to recall most impressive fashion product that they bought in Korea during their recent visit and to answer if it was a planned or unplanned purchase. This study also measures emotions during product purchases and usage satisfaction. The respondents are categorized into heavy and light buyers according to purchasing power to determine the moderating effects of purchase amount. The results indicate that planned purchases tend to deliver positive emotions that enhance product usage satisfaction. In the case of unplanned purchases, without the mediating role of positive shopping emotions, it has a negative impact on product attitude and shows the importance of positive emotions during shopping. The influence of unplanned purchases on shopping emotions or product attitude in light buyers is not significant for the moderating effect of purchasing power. Only planned purchases trigger product usage satisfaction when it is mediated by positive emotions.

Objectives: The purpose of the study is to evaluate the dental website usability in Korea. The dental website included dental university hospital, network dental hospital and dental office. Methods: The study was carried out by three age groups including twenties, thirties, and forties. Each group consisted of ten customers and evaluated twelve websites of dental hospitals. Each was assigned to four hospitals and three tasks including easiness of online reservation, preventive information, and treatment information. They filled out the self-administered questionnaire. The questionnaire included the easiness of on-line reservation, satisfaction on the quality and quantity of preventive informations, satisfaction on the quality and quantity of treatment informations, predictiveness on the sub-menu, usefulness of site map, information on the main page of web site, usefulness of decision on visit to dentistry, and revisit intention. Results: The easiness of on-line reservation was the highest in the private dental office, and university dental hospital and network dental hospitals followed in conducting task(1). The anticipated value and measurement on the usefulness of web site were the lowest in network dental hospitals and the time interval between two values was 57 seconds. This discrepancy showed the largest difference. The satisfaction on treatment information in task(3) was higher than that of the satisfaction on preventive information in task (2). The revisit intention was the highest in dental university hospitals. Conclusions: This study showed the comparison in usefulness of web site of university dental hospitals, network dental hospitals and private dental office. The web site focused on the treatment information rather than preventive information. This study suggested that the most important function of dental web site would be the preventive information that was mainly operated by the role of dental hygienists rather than treatment information in the future.
