Automated synthesis of norms in social networks

We introduce a legislation mechanism, capable of automatically synthesise norms from a multi-agent domain, to synthesise norms in a participatory manner, namely desmon. Moreover, we have created an agent-based on-line community simulator to model the interactions within their users

Applying IRON to a Virtual Community Scenario

Normative systems (norms) have been widely proposed as a technique for coordinating multi-agent systems (MAS). The automated synthesis of norms is a complex problem that remains open. IRON (Intelligent Robust On-line Norm synthesis mechanism) is a novel mechanism for the on-line automated synthesis of norms for MASs. IRON produces conflict-free norms that characterise necessary conditions for coordination, without over-regulation. In the past, IRON successfully regulated a traffic scenario even in the presence of non-compliant agents. In this paper, we apply IRON to synthesise norms for a virtual community scenario, where agents are users that share contents within the community. As a result, IRON synthesises norms that prevent users from uploading undesirable contents (i.e., those that users complain about). © 2013 The authors and IOS Press.

Extending NormLab to Spur Research on Norm Synthesis

On-line norm synthesis is a widely used approach to facilitate coordination in MASs. In [2] we introduced NormLab, a computational framework to support research on on-line norm synthesis. That framework provides functionalities to model, simulate and analyse norm synthesis algorithms in an agent-based simulation environment. Here we present several extensions to that work, providing a benchmark for research on norm synthesis in MAS.Work funded by projects AT (CSD2007-0022), COR (TIN2012-38876-C02-01/02), and 2009-SGR-1434.

NormLab: A Framework to Support Research on Norm Synthesis (Demonstration)

MAS research has investigated norms as a means to coordinate open multi-agent systems (MAS). This has spurred a strand of research on on-line norm synthesis algorithms for MASs. However, to the best of our knowledge, currently there is no computational framework to support the development and study of on-line norm synthesis. Here we present NORMLAB, a novel framework to support norm synthesis research, highlighting its important features. We also outline the operation of two novel on-line norm synthesis strategies, which significantly outperform the state of the art

1Using IRON to Build Frictionless On-line Communities

On-line communities are virtual environments where users exchange contents. Occasionally, users ’ interactions lead to frictions, jeopardising the proper functioning of the community. Trying to avoid frictions, on-line communities typically incorporate a regulation mechanism based on (i) norms set by the owner of the community; and (ii) human moderators. In this paper we present a participatory legislation mechanism that automatically synthesises norms for an on-line community based on users ’ complaints about contents. With this aim, we present an agent-based simulator to model the interactions within on-line communities. We then exploit IRON, an automatic norm synthesis mechanism, to regulate simulated on-line communities. As a result, IRON synthesises norms that prevent a user from uploading contents that users regard as unacceptable by means of complaints, hence avoiding frictions
