The main objective of this study is to investigate the determinants of consumer trust in e-business. It examines consumer perceptions trust in a Web site and address following research questions: What factors influence consumer trust in a Web site and what specific Web site cues are associated with trust and satisfaction? We test our hypothesis in a empirical data from 568 consumers across 4 Web sites. By factor analysis, the results show that Web site characteristics are such as product information and purchase process , system stability, navigation, privacy(security), design, information of seller, pay methods, and customer service. We also find that brand and Web site characteristics such as Web site design, navigation, privacy(security), and customer service can explain over 59% of the variance in Web site trust and 60% in satisfaction. The results offer important implication for Web site strategies that include the manipulation of factors influencing Web site trust. And the future directions of the present research are discussed.

We are sometimes interacting with people who we know nothing and facing with the difficult task of making decisions involving risk in social network. To reduce risk, the topic of building Web of trust is receiving considerable attention in social network. The easiest approach to build Web of trust will be to ask users to represent level of trust explicitly toward another users. However, there exists sparsity issue in Web of trust which is represented explicitly by users as well as it is difficult to urge users to express their level of trustworthiness. We propose a fuzzy-based inference model for Web of trust using user behavior information in social network. According to the experiment result which is applied in Epinions.com, the proposed model show improved connectivity in resulting Web of trust as well as reduced prediction error of trustworthiness compared to existing computational model.

본 연구는 벤처기업의 웹사이트에 대한 신뢰의 선행요인과 결과요인의 구조적 관계를 확인하고 웹사이트에 대한 신뢰, 만족도 및 행동의도에 영향을 주는 선행변수를 밝히고자 하였다. 이를 위해 대학생 123명을 대상으로 3개의 벤처기업의 웹사이트에 대한 과제 수행을 하도록 한 후 방문 웹사이트에 대한 지각을 측정하였다. 그 결과 첫째, 벤처기업의 웹사이트의 특성을 측정하기 위한 문항들에 대한 요인분석결과, 웹사이트의 디자인, 비즈니스 기능의 지원, 인터페이스, 기술, 커뮤니티, 콘텐츠의 6개 요인이 추출되었다. 둘째, 벤처기업의 웹사이트 특성 6개 요인을 선행변수로, 웹사이트의 신뢰도, 만족도 및 행동의도 의 3개 요인을 내생요인으로 한 모형을 구성하여 관계구조 모형에 대한 검증을 시도하였다. 공분산 구조분석 결과, 전반적 부합지수들은 비교적 양호하게 나타났으며, 경로도형에서는 웹사이트의 디자인, 인터페이스, 기술 및 커뮤니티의 요인들이 웹사이트의 만족도로 가는 경로가, 그리고 디자인과 콘텐츠가 웹사이트의 신뢰도로 가는 경로에서 유의하게 나타났다. 내생요인간의 경로는, 만족도는 행동의도에 영향을 주는 것으로 나타났으나 웹사이트의 신뢰도는 만족도의 매개역할을 통해 행동의도에 영향을 주는 것으로 나타났다. 이러한 결과를 기초로 쇼핑몰 운영에 있어서의 시사점을 논의하였다.

A lack of trust in the technical and institutional environments surrounding the web can hinder e-commerce adoption, because Internet social cues are minimal and trust is difficult th establish. Web vendors must act purposefully to overcome consumer perceptions of uncertainty and risk by building trust-both in their own web sites and in the broader Internet environments. Trust makes consumers comfortable by sharing personal information making purchases, and acting on web vendor advice-behaviors essential to wide-spread adoption of e-commerce. Understanding the nature and antecedents of trust is, therefore, a major issue for both Internet researchers and practitioners. Prior research on e-commerce trust has used diverse, incomplete, and inconsistent definitions of trust therefore, making it difficult to compare results across studies. This study tried to and the empirical relationships among the trust-related factors on the usage of Internet shooing mall. The model includes five high-level constructs-disposition to trust institution-based trust trusting beliefs, trusting intention and environmental factors. The results showed that the disposition to trust and the environmental factors had a significant effect on the web site trust however, their effect was not consistent Moreover, the model suggested in this study need to be extended including with the more sociological factors and results in this study required to be verified with those extended model.

In this paper, we suggested a model that reflects the role played by the consumer's regulatory focus (promotion focus and prevention focus) as determinant factors of trust in the Web site. Also, we considered the moderating effects of consumers' purchasing experience toward online shopping. We conducted a two-month survey of 230 individuals using online shopping sites for hypotheses testing. The study results are summarized as follows. Firstly, promotion focused consumers showed higher trust to a web site compared to prevention focused consumers. Secondly, the moderating effect of purchasing experience between regulatory focus and consumer trust to a web site is statistically significant. The effect of a prevention focused consumers on consumer trust to a web site is stronger when purchasing experience toward online shopping is high compared to low. Based on these findings, this study presents practical and academic implications of the research.

This paper is an exploratory study to investigate the influence of characteristics of local government web-sites on user satisfaction and trust. The objective of this research is to identify the characteristics of local government web-sites influencing on user satisfaction and trust, and determine how they affect user satisfaction and trust. From the literature review, we identify four characteristics which are expected to influence on user satisfaction: technical, information, customer-oriented, and work-performing characteristics. In addition, we develop research model that the four characteristics are expected to affect user satisfaction and trust via users' perceived values. The results of the research are as follows. The technical, customer-oriented, and work-performing characteristics significantly affects perceived values, which significantly affected user satisfaction and trust. Perceived value is partially mediated by user satisfaction in affecting user trust. The characteristics of local government web-sites affecting perceived values differed partially by the purpose of visitor. As for the personal goal, the technical, customer-oriented, and work-performing characteristics significantly affect perceived values, with the technical and customer-oriented characteristics having more significant effects. As for the business goal, the technical, information, work-performing characteristics significantly affected perceived values, with information characteristics having more significant effects.

Web services instances can be classified into two categories, namely trusted and untrusted from users. A web service with high throughput (TP) and low response time (RT) instance values is a trusted web service. Web services are not trustworthy due to the mismatch in the guaranteed instance values and the actual values achieved by users. To perform web services selection from users' attained TP and RT values, we need to verify the correct prediction of trusted and untrusted instances from invoked web services. This accurate prediction of web services instances is used to perform the selection of web services. We propose to construct fuzzy rules to label web services instances correctly. This paper presents web services selection using a well-known machine learning algorithm, namely REPTree, for the correct prediction of trusted and untrusted instances. Performance comparison of REPTree with five machine learning models is conducted on web services datasets. We have performed experiments on web services datasets using a ten k-fold cross-validation method. To evaluate the performance of the REPTree classifier, we used accuracy metrics (Sensitivity and Specificity). Experimental results showed that web service (WS1) gained top selection score with the (47.0588%) trusted instances, and web service (WS2) was selected the least with (25.00%) trusted instances. Evaluation results of the proposed web services selection approach were found as (asymptotic sig. = 0.019), demonstrating the relationship between final selection and recommended trust score of web services.
