Adaptiveness and social-compliance in trust management within virtual communities

Abstract

The success of virtual communities (VCs) relies on collaboration and resource sharing principles, making trust a priority for each member. The work presented in this paper addresses the problem of trust management in open and decentralised virtual communities. We address this problem by proposing an Adaptive and Socially-Compliant Trust Management System (ASC-TMS) adopting a multi-agent based approach. Our proposal relies on the joint use of trust policies and meta-policies, which allow VC members to exhibit adaptive (i.e., in accordance with environment changes) and socially-compliant (i.e., in accordance with the collective policies specified by the community members) behaviour. The experiments reported in this paper focus on the socially-compliant aspect of ASC-TMS. They aim at evaluating different policy integration algorithms.

Enabling Trust Assessment In Clouds-of-Clouds

“…e above matrix is traditionally used by cloud providers to select the best candidate provider to collaborate with within a multi-cloud (cf., [20]). In our approach, we advocate the extension of it's use to customers as it contains accurate and valuable information about the e ective level of ful llment of each provider in their previous interactions [19].…”

“…Trust is a well established mechanism that supports cooperation and collaboration in open and decentralized systems [8,20]. Consequently, this concept has been extensively investigated in the last een years resulting in the emergence of numerous trust models [10].…”

“…Consequently, this concept has been extensively investigated in the last een years resulting in the emergence of numerous trust models [10]. Each model tried to represent the information a participant should collect about the others and proposed an evaluation schema to derive trust from that information [20]. e objective of this section is not to review the complete literature on this subject, there exist several surveys that provided more comprehensive studies (c.f.…”
