Estimating levels of user trust is important for maintaining continuous use of e-commerce systems because trust alleviates user concerns about the invisibility of service providers or their reputation. Conventional trust estimation approaches such as policy-and reputationbased reasoning have focused on the experience of e-commerce systems at an early stage. However, only a few trust reasoning methods have considered the mature stage, which is more related to continuance intention. We propose a trust reasoning method dedicated to the mature stage of using e-commerce systems. In particular, a new method of unobtrusively estimating the degree of user intimacy is developed, because intimacy has been highly associated with trust as well as reputation. Our experiments show that the proposed method is valid and can be used in conjunction with reputation-based trust reasoning.

With the development and popularization of Internet, the competition of SNS market is now getting fiercer and fiercer. SNS service providers need to keep updating their service to sustain their customers' continuance use. However, due to the homogenization of functions and services from different applications provided by different developers, there comes a new phenomenon that users shift from one SNS to another SNS. In line with this, the current study aims to explore factors affecting switching intention among SNS users by applying migration theory which explains people's migration behavior from one place to another. Findings from surveys of Korean and Chinese college students suggest that there was a difference of factors influencing switching intention among the two countries. For Korean college students, alternative attraction was the strongest factor leading to SNS switching intention. On the other hand, peer pressure was the strongest factor leading to SNS switching intention among Chinese college students.

Trust has been identified as crucial to intention to continue to use e-commerce systems. Although trust is inherent in relationship-based practices, most studies on trust have focused on influences on customer trust. From the viewpoint of mutual trust, few empirical studies have examined the effect of users' perceived trust from an e-commerce website on customer trust in that website, despite the obvious importance of this issue, particularly in the field of e-commerce. This paper empirically examines the role of customer perception of trust in the customer on the part of e-commerce websites. In addition, this study explores the ability of e-commerce websites' trusting actions to transfer positive impressions that encourage trust in those sites. The results indicate that in the e-commerce context, a website's trusting actions are important to customer perception of being trusted by and trusting in e-commerce websites.

Generally speaking, user behavior in the post-adoption period is different from that in the pre-adoption period. Users come to make on their experiences of IT use whether they will continue to use it or not. Most theories about the user behaviors in the pre-adoption period are limited in describing them after adoption since they do not consider user's experiences of using the adopted IT and the beliefs formed by those experiences. Therefore, in this study, we explore user's experiences and beliefs such as familiarity, satisfaction and habits in the post-adoption period and examine how they affect user's intention to continue in using Mobile Social Network Service. Through literature reviews, we proposed the conceptual model to explain the role of users' habits in continuance of IT post-adoption stage. Then, we examine the impact of the constructs to affect the intention to continue using the Mobile SNS. The results show that the intention to continue to use Mobile SNS is strongly influenced by users' habits, satisfaction and familiarity; users' habits is strongly influenced by satisfaction and familiarity; satisfaction is strongly influenced by familiarity.

This study focused on user trust in ChatGPT, a generative AI technology, and explored the factors that affect usage status and intention to continue using, and whether the influence of trust varies depending on the purpose. For this purpose, the survey was conducted targeting people in their 20s and 30s who use ChatGPT the most. The statistical analysis deploying IBM SPSS 27 and SmartPLS 4.0. A structural equation model was formulated on the foundation of Bhattacherjee's Expectation-Confirmation Model (ECM), employing path analysis and Multi-Group Analysis (MGA) for hypothesis validation. The main findings are as follows: Firstly, ChatGPT is mainly used for specific needs or objectives rather than as a daily tool. The majority of users are cognizant of its hallucination effects; however, this did not hinder its use. Secondly, the hypothesis testing indicated that independent variables such as expectation- confirmation, perceived usefulness, and user satisfaction all exert a positive influence on the dependent variable, the intention for continuance intention. Thirdly, the influence of trust varied depending on the user's purpose in utilizing ChatGPT. trust was significant when ChatGPT is used for information retrieval but not for creative purposes. This study will be used to solve reliability problems in the process of introducing generative AI in society and companies in the future and to establish policies and derive improvement measures for successful employment.
