In this article, we describe an approach for computing the current trust level of individual users towards an online system and present initial validation results from a small-scale experiment. This trust computational model relies upon survey research for identifying the set of key trust attributes and grouping users into four segments of expected behaviors. Each user’s initial trust level is ...

Trust is an important tool in human life, as it enables people to cope with the uncertainty caused by the free will of others. Uncertainty and uncontrollability are also issues in computer-assisted collaboration and electronic commerce in particular. A computational model of trust and its implementation can alleviate this problem. This survey is directed to an audience wishing to familiarize th...

The World Wide Web encourages widely-distributed, open, decentralised systems that span multiple administrative domains. Recent research has turned to trust management [4] as a framework for decentralising security decisions in such systems. However, whilst traditional security measures such as cryptography and encryption are well-understood (theoretically and empirically), the same cannot be s...

Trust has attracted extensive attention in social science and computer science as a solution to enhance the security of the system. This paper proposes a trust evaluation model based on D-S evidence theory and sliding windows for cloud computing. The timeliness of the interaction evidence as the first-hand evidence is reflected by introducing sliding windows. The direct trust of entities is com...

The inherent weakness of the data on user ratings collected from web, such as sparsity and cold-start, has limited the data analysis capability and prediction accuracy in recommender systems (RS). To alleviate this problem, trust has been incorporated in collaborative filtering (CF) approaches with encouraging experimental results. In this paper, we propose a computational model for trust-based...

Automated support of design teams, consisting of both human and automated systems, requires an understanding of the role of trust in distributed design processes. By explicitating trust, an individual designer’s decisions become better understood and may be better supported. Each individual designer has his or her private goals in a co-operative design setting, in which requirement conflicts an...

A key-issue for the effectiveness of collaborative decision support systems is the problem of the trustworthiness of the entities involved in the process. Trust has been always used by humans as a form of collective intelligence to support effective decision making process. Computational trust models are becoming now a popular technique across many applications such as cloud computing, p2p netw...

Recent developments in the pervasiveness and mobility of computer systems in open computer net­ works have invalidated traditional assumptions about trust in computer communications security. In a fundamentally decentralised and open network such as the Internet, the responsibility for answer­ ing the question of whether one can trust another entity on the network now lies with the individual a...

We propose generic declarative definitions of individual and collective trust relations between interacting agents and agent collections, and trust domains of trust-related agents in distributed systems. Our definitions yield (1) (in)compatibility, implicational, and transitivity results for trust relationships, including a Datalog-implementability result for their logical structure; (2) comput...

the purpose of the present study is to investigate effective factors in making people willing to repurchase sports match tickets online with the approach of extending technology acceptance model. this research is considered applied regarding its purpose, descriptive- survey regarding its method, and is based on structural equation model (sem). the participants are iran's national volleybal...
