    A Conviviality Measure for Early Requirement Phase

    In this paper, we consider the design of convivial multi-agent systems. Conviviality has recently been proposed as a social concept to develop multi-agent systems. In this paper we introduce temporal dependence networks to model the evolution of dependence networks and conviviality over time, we introduce epistemic dependence networks to combine the viewpoints of stakeholders, and we introduce normative dependence networks to model the transformation of social dependencies by hiding power relations and social structures to facilitate social interactions. We show how to use these visual languages in design, and we illustrate the design method using an example on virtual children adoptions

    In this paper we discuss the shift from a legal to an interactionist view on normative multiagent systems, examples, and ten new challenges in this more dynamic setting

    Contextual and Possibilistic Reasoning for Coalition Formation

    Get PDF
    In multiagent systems, agents often have to rely on other agents to reach their goals, for example when they lack a needed resource or do not have the capability to perform a required action. Agents therefore need to cooperate. Then, some of the questions raised are: Which agent(s) to cooperate with? What are the potential coalitions in which agents can achieve their goals? As the number of possibilities is potentially quite large, how to automate the process? And then, how to select the most appropriate coalition, taking into account the uncertainty in the agents' abilities to carry out certain tasks? In this article, we address the question of how to find and evaluate coalitions among agents in multiagent systems using MCS tools, while taking into consideration the uncertainty around the agents' actions. Our methodology is the following: We first compute the solution space for the formation of coalitions using a contextual reasoning approach. Second, we model agents as contexts in Multi-Context Systems (MCS), and dependence relations among agents seeking to achieve their goals, as bridge rules. Third, we systematically compute all potential coalitions using algorithms for MCS equilibria, and given a set of functional and non-functional requirements, we propose ways to select the best solutions. Finally, in order to handle the uncertainty in the agents' actions, we extend our approach with features of possibilistic reasoning. We illustrate our approach with an example from robotics

    Combining Norms, Roles, Dependence and Argumentation in Agreement Technologies

    Get PDF
    A major challenge for Agreement Technologies is the combination of existing technologies and rea- soning methods. In this paper we focus on the three core layers of the Agreement Technologies tower, called Norms, Organization and Argumentation. We present a framework for arguing about agreements based on norms, roles and dependence, together with a case study from the sharing economy

    Abstract. In this paper we present a new model for the requirements analysis of a system. We offer a conceptual model defined following a visual modeling language, called dependence networks. TROPO

    Convivial Making: Power in Public Library Creative Places

    Get PDF
    In 2011, public libraries began to provide access to collaborative creative places, frequently called “makerspaces.” The professional literature portrays these as beneficial for communities and individuals through their support of creativity, innovation, learning, and access to high-tech tools such as 3D printers. As in longstanding “library faith” narratives, which pin the library’s existence to widely held values, makerspace rhetoric describes access to tools and skills as instrumental for a stronger economy or democracy, social justice, and/or individual happiness. The rhetoric generally frames these places as empowering. Yet the concept of power has been neither well-theorized within the library makerspace literature nor explored in previous studies. This study fills the gap between the rhetoric and the reality of power, as described by the stakeholders, including staff, trustees, and users of the library. Potentially, library creative places could be what Ivan Illich calls convivial tools: tools that manifest social relations involving equitable distributions of power and decision-making. A convivial tool ensures that users may decide to which end they would like to apply the tool, and thus are constitutive of human capabilities and social justice. However, the characterization of library makerspaces in the literature evokes a technologically deterministic entrepreneurialism that marginalizes many types of making, and reduces the power of individuals to choose the ends to which they put this tool. This multi-site ethnographic study seeks to unravel the currents of power within three public library creative places. Through participant observation, document analysis, and interviews, the study traces the mechanisms and processes by which power is distributed, as enacted by institutional practices—the spaces, policies, tools, and programs—or through individual practices. The study finds seven key tensions that coalesce around the concept of conviviality, and also reveals seven capabilities of convivial tools that the users and providers of these spaces identify as crucial to their successful and satisfying implementation. As a user-centered exploration of the interactions of power in a public institution, this study can benefit a range of organizations that aim to further inclusion, equity, and social justice

    Computational Theory of Mind for Human-Agent Coordination

    Get PDF
    In everyday life, people often depend on their theory of mind, i.e., their ability to reason about unobservable mental content of others to understand, explain, and predict their behaviour. Many agent-based models have been designed to develop computational theory of mind and analyze its effectiveness in various tasks and settings. However, most existing models are not generic (e.g., only applied in a given setting), not feasible (e.g., require too much information to be processed), or not human-inspired (e.g., do not capture the behavioral heuristics of humans). This hinders their applicability in many settings. Accordingly, we propose a new computational theory of mind, which captures the human decision heuristics of reasoning by abstracting individual beliefs about others. We specifically study computational affinity and show how it can be used in tandem with theory of mind reasoning when designing agent models for human-agent negotiation. We perform two-agent simulations to analyze the role of affinity in getting to agreements when there is a bound on the time to be spent for negotiating. Our results suggest that modeling affinity can ease the negotiation process by decreasing the number of rounds needed for an agreement as well as yield a higher benefit for agents with theory of mind reasoning.</p
