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.}, keywords = {normative systems, Norms, on-line norm synthesis}, isbn = {978-1-4503-2738-1}, author = {Javier Morales and Iosu Mendizabal and David Sanchez-Pinsach and Maite L{\'o}pez-S{\'a}nchez and Michael Wooldridge and Wamberto W.

Occasionally, users{\textquoteright} 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{\textquoteright} 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.}, keywords = {norm synthesis, normative multi-agent systems, on-line communities}, author = {Javier Morales and Iosu Mendizabal and David Sanchez-Pinsach and Maite L{\'o}pez-S{\'a}nchez and Juan A.

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).}, isbn = {978-1-61499-319-3}, author = {Javier Morales and Iosu Mendizabal and David Sanchez-Pinsach and Maite L{\'o}pez-S{\'a}nchez and Juan A.
