As web-based online communities are rapidly growing, the agents in the communities need to know their measurable belief of trust for safe and successful interactions. In this paper, we propose a computational model of trust resulting from available feedbacks in online communities. The notion of trust can be defined as an aggregation of consensus given a set of past interactions. The average trust of an agent further represents the center of gravity of the distribution of its trustworthiness and untrustworthiness. Furthermore, we precisely describe the relationships among reputation, trust and average trust through concrete examples showing their computations. We apply our trust model to online social networks in order to show how trust mechanisms are involved in the rational purchasing decision-making of buyers and sellers, and we summarize our simulation results.

소셜 네트워크를 통해 생산 유통되는 정보들은 신뢰할 수 없는 불분명한 정보들이 많고 그런 정보들이 무분별하게 확산되기 때문에 사용자들은 정보에 대한 신뢰성 여부를 판단하기가 힘들다. 특히 정보의 신뢰성에 대한 평가가 전적으로 사용자들의 판단에 맡겨지고 있는 상황에서, 온라인 정보의 신뢰도에 대한 체계적인 평가 방안의 마련이 절실하다. 본 논문에서는 소셜네트워크서비스의 신뢰도 평가 지표로서 KTI (Korean Trust Index for SNS)를 설계하여, 서비스 사용자들이 정보의 신뢰성을 판단할 수 있는 기준을 제시하였으며, 이를 통해 사회적 신뢰 수준을 분석할 수 있도록 하였다. SNS의 서비스 특성을 고려하여, 신뢰도에 영향을 주는 요인을 정의하였고 이를 바탕으로 온라인에서 유통되는 정보에 대한 신뢰도를 평가할 수 있는 신뢰모델을 설계하고 신뢰지수 KTI를 제시하였다. 신뢰지수 KTI의 개발은 SNS에 대한 신뢰 수준을 측정하여 이를 정량화함으로써, SNS 연결망을 효율적으로 활용하기 위한 신뢰 확보가 가능할 것으로 기대한다.

The purpose of this study was to empirically investigate the relationship between hospital employeesʼ perceptions of organizational politics, organizational effectiveness such as job satisfaction, organizational commitment, and turnover intention. We also evaluated the moderating effect of organizational trust on the relationships between POPs and organizational effectiveness. By analyzing 726 employeesʼ data including physicians, nurses, medical technicians, and administrators from one private hospital, POPs was found to have had a highly negative relationship with job satisfaction and organizational commitment while a highly positive relationship with turnover intention. Furthermore, organizational trust moderated the relationship between POPs and job satisfaction, and also POPs and turnover intention, while no moderating effect appeared between POPs and organizational commitment. Within the organization, employees who are in a group with high organizational trust have low job satisfaction and high turnover intention when they have high POPs rather than a group with low organizational trust. Further the implications of these results and future directions of the study have been discussed.

A blockchain is an underlying technology and basic infrastructure of the Bitcoin system. At present, blockchains and their applications are developing rapidly. However, the basic research of blockchain technology is still in the early stages. The efficiency and reliability of blockchain communication is one of the research problems that urgently need to be studied and addressed. Existing algorithms may be less feasible for blockchain-based communication because they only consider a single communication factor (node communication capability or node trust degree) and only focus on a single communication performance parameter(communication time or communication reliability). In this paper, to shorten the validation time of blockchain transactions and improve the reliability of blockchain-based communication, we first establish a multi-link concurrent communication model based on trust degree, and then we propose a novel integrated factor communication tree algorithm (IFT). This algorithm comprehensively considers the node communication link number and the node trust degree and selects several nodes with powerful communication capacity and high trust as the communication sources to improve the concurrency and communication efficiency. Simulation results indicate that the IFT algorithm outperforms existing algorithms. A blockchain communication routing scheme based on the IFT algorithm can increase communication efficiency by ensuring communication reliability.

Purpose: Trust plays an important role in e-commerce because consumers perceive more risk involved with this type of shopping than traditional way of shopping. Trust is defined as complex and multidimensional issue. This paper argues that trust should be considered to have two important components as trust belief and trust intention, in which trust belief has three components as competence, integrity and benevolence. Research design, data and methodology: This study examines the relationship between retailer website quality (web design, navigation, information), reputation and risk toward trust. In addition, trust and risk toward buying behavior are also considered, leading to customer satisfaction. The paper is conducted on a sample of 594 customers with direct experience of online shopping in Vietnam. Both confirmatory factor analysis (CFA) and a structural equation model (SEM) were utilised. Results: Empirical findings from this paper indicate that trust is high order construct. Website quality and reputation have positive impacts on customers' trust. Trust has a positive relationship to buying behavior and customers' satisfaction while perceived risk has negative relationship to buying behavior. In contrast, a relationship between perceived risk and trust is not supported in this study. Conclusions: Improving reputation and website quality (especially information) may increase customers' trust and eventually lead to purchase decision.

Trust management is one of the most challenging issues for the highly heterogeneous Internet of Things (IoT). In the context of the IoT, it is difficult to evaluate the node's trustworthiness in the same trust model when a node provides different services. Guaranteeing the availability of the trust management service is another significant challenge because of the dynamic nature of IoT environments. With these issues in mind, this paper propose a robust and adaptive trust management system for the IoT that is able to measure the trustworthiness of nodes based on feedbacks collected from participants in a specific context and ensure the availability of trust management services. The main contributions of our system are: 1) Proposing a partly decentralized trust management framework, which improves the resiliency of the trust mechanism; 2) Proposing an adaptive trust evaluation scheme and a three-dimensional context representation makes trust evaluation more accurate and specific; 3) Enhancing the adaptive trust evaluation scheme by incorporating a bad behavior factor in trust estimation, which efficiently distinguishes misleading feedbacks from On-Off attacks. Simulation results show the good performance of the proposed system and especially show effectiveness against On-Off attacks compared to other trust mechanisms.

Trust as one of important social relations has attracted much attention from researchers in the field of social network-based recommender systems. In trust network-based recommender systems, there exist normally two roles for users, truster and trustee. Most of trust-based methods generally utilize explicit links between truster and trustee to find similar neighbors for recommendation. However, there possibly exist implicit correlations between users, especially for users with the same role (truster or trustee). In this paper, we propose a novel Collaborative Filtering method called CF-TC, which exploits Trust Context to discover implicit correlation between users with the same role for recommendation. In this method, each user is first represented by the same-role users who are co-occurring with the user. Then, similarities between users with the same role are measured based on obtained user representation. Finally, two variants of our method are proposed to fuse these computed similarities into traditional collaborative filtering for rating prediction. Using two publicly available real-world Epinions and Ciao datasets, we conduct comprehensive experiments to compare the performance of our proposed method with some existing benchmark methods. The results show that CF-TC outperforms other baseline methods in terms of RMSE, MAE, and recall.
