In open settings, the participants are autonomous and there is no central authority to ensure the felicity of their interactions. When agents interact in such settings, each relies upon being able to model the trustworthiness of the agents with whom it interacts. Fundamentally, such models must consider the past behavior of the other parties in order to predict their future behavior. Further, i...

On the Web, it is possible for anyone to publish linked open data as RDF. Whilst this has huge potential to benefit data integration efforts, it highlights challenges of assessing data quality and trust. Nanopublication is an approach to data and knowledge publication in which assertions are individually encoded in RDF along with details about provenance, context and attribution. Collectively t...

This article developed a framework for trust management in mobile ambient home network with a view to secure the home devices and channel against attacks. The framework was design using mobile ad hoc network and social networking concept. The trust management, global reputation aggregation which considered the direct and indirect communication of home devices and remote devices was employed to ...

We present a prototype of agent-based intrusion detection system designed for deployment on high-speed backbone networks. The main contribution of the system is the integration of several anomaly detection techniques by means of collective trust modeling within a group of collaborative detection agents, each featuring a specific detection algorithm. The anomalies are used as an input for the tr...

In Web-based social networks (WBSN), social trust relationships between users indicate the similarity of their needs and opinions. Trust can be used to make recommendations on the web because trust information enables the clustering of users based on their credibility which is an aggregation of expertise and trustworthiness. In this paper, we propose a new approach to making recommendations bas...

We study a general task allocation problem, involving multiple agents that collaboratively accomplish tasks and where agents may fail to successfully complete the tasks assigned to them (known as execution uncertainty). The goal is to choose an allocation that maximises social welfare while taking their execution uncertainty into account. We show that this can be achieved by using the post-exec...

WANG, YONGHONG. Evidence-Based Trust in Distributed Agent Systems. (Under the direction of Professor Munindar P. Singh). Trust is a crucial basis for interactions among parties in large, open distributed systems. Yet, the scale and dynamism of such systems make it infeasible for each party to have a direct basis for trusting another party. For this reason, the participants in an open system mus...

To mitigate the attacks by malicious peers and to motivate the peers to share the resources in peer-to-peer networks, several reputation systems have been proposed in the past. In most of them, the peers evaluate other peers based on their past interactions and then aggregate this information in the whole network. However such an aggregation process requires approximations in order to converge ...

Trust relation, as defined in Social Network Analysis (SNA), is one of the recent notions considered decision making. This inspired our integration trust relation constructing a similarity–trust network. Similarity experts' preferences analyzed inclusively with by defining new combination function both attributes. The agglomerative hierarchical clustering approach applied to group experts into ...
