“…We claim that the notion of specialized role proposed in Hermoso et al (2013) might be used to establish performance standards and so facilitate the agreement on commitments among agents. We therefore envision the possibility of going from roles as expectations of behaviour (Winikoff and Cranefield 2009) or performance (Hermoso et al 2013) to the explicit handling of such expectations as de facto standards that may be committed to. Standards are therefore not imposed by the system, but promoted after they have been identified as current practice among a group of agents.…”

“…The rationale behind creating and maintaining performance standards relies on the concept of role proposed by Hermoso et al (2013). In this work, the authors claim that in open systems the evolution of the population should entail that organisational structures evolve as well.…”

“…Taking inspiration from social sciences, concepts such as (electronic) institutions (Esteva et al 2001;Dignum and Dignum 2001;Fornara et al 2008), norms (Boman 1999;López y López and Luck 2003;Boella et al 2006;García-Camino et al 2007;Lopes Cardoso and Oliveira 2008), commitments (Singh 1999;Fornara and Colombetti 2003;Fasli 2003), conventions (Walker and Wooldridge 1995;Conte and Castelfranchi 1999), and roles (Hubner et al 2002;Fasli 2006;Winikoff and Cranefield 2009;Hermoso et al 2013) have been introduced and exploited in the multi-agent systems domain.…”

“…Some of these approaches comprise situational trust models (Rehak et al 2006;Tavakolifard et al 2008;Hermoso et al 2013;Urbano et al 2011), in the sense that agents are evaluated regarding their performance in specific contexts, situations, or tasks. A typical assumption in these models is that the measured trustworthiness of an agent is updated as new experiences and evidence are collected from the environment.…”

“…Taking an organizational approach, and looking at the society from a role-specialization perspective, Hermoso et al proposed role evolution (Hermoso et al 2013) as a guideline to develop a coordination mechanism that enhances partner selection processes for task delegation purposes. This approach is based on examining the agent society and on identifying "run-time roles" -so building a role taxonomy -that clusters agents with similar skill patterns for a certain (set of) task(s).…”

From roles to standards: a dynamic maintenance approach using incentives

Social coordination has been addressed in multiagent systems, making use of concepts such as institutions, norms, commitments, conventions, roles, or trust. In this paper, we argue the need to tackle open and dynamic environments with yet another concept: the notion of a standard, seen as a measurable and non-committing expectation. Not much work has been done in the field of multi-agent systems addressing the evolving nature of roles, especially in open systems, in which changes in the population bring about changes in the expectations generated from roles. Using standards measured from roles as the focus of attention, we propose an incentive-based mechanism to maintain roles over time. This approach is put in contrast with reorganization, which is needed when incentives are not cost-effective. Different search algorithms are proposed to illustrate incentive-based maintenance. Some empirical results are shown based on the principal-agent model from economics.

Computational trust has been modelled for supporting agents in selecting partners in open and distributed multiagent systems. Most of current models are based on the experience of transactions in the past with a given partner or on reputation of a partner from other agents in the system. However, these models could not deal with the case, a new coming agent has no experience with partners or could not obtain the information about the reputation of partners. Then, agents in the system and the new one may encounter an obstacle in estimating trust on corresponding partners. In this paper, we introduce a novel mechanism for computing trust of a new coming partner by means of some similarity in a profile of the new agent and the ones of well-known agents. Experiments have been conducted to evaluate the proposed model in the scenario of an e-commerce environment. Our experimental results indicate that the combination model with similarity trust significantly improves computational results, in some particular situation, compared with some recent trust models.
