Direct interaction and explicit communication are not always the best approaches for achieving coherent systemic behaviour in the context of Multi-Agent Systems (MAS). This is evident when taking into account recent approaches dealing with environment-based coordination such as stigmergy and, more generally, mediated interaction. In this paper we propose a(More)
This report documents the program and the outcomes of Dagstuhl Seminar 12111 “Normative Multi-Agent Systems”. Normative systems are systems in the behavior of which norms play a role and which need normative concepts in order to be described or specified. A normative multi-agent system combines models for normative systems (dealing for example with(More)
A new kind of smart space is emerging in which digital, physical, and social layers are strongly intertwined. These spaces extend the classic assistive functionality of ambient intelligence toward more proactive possibilities, where the smart environment not only monitors people as they perform tasks but also influences their plans and intentions. The(More)
concepts ("freedom") differ from concrete ones ("cat"), as they do not have a bounded, identifiable, and clearly perceivable referent. The way in which abstract concepts are represented has recently become a topic of intense debate, especially because of the spread of the embodied approach to cognition. Within this framework concepts derive their meaning(More)
The aim of this paper is to provide an analysis of institutional actions from the standpoint of cognitive science. The notion of constitutive rules have been proposed to describe the conceptual nature of institutions. In this paper it is extended to cover specific processes of ‘recognition’ that provide the agents with additional artificial powers. The(More)
While the role of mutual beliefs in coordination and collaboration has been extensively acknowledged, the cognitive processes supporting their establishment are left unexplained or simply assumed. Notions like “public event” or “public announcement” usually refer to events or speech acts that create such mutual information states. The goal of this paper is(More)
The goal of this paper is to show the normative component of a convention adopted by a population of cognitive agents. To address this aim we will defend two distinct thesis. The former is that even simple predictions developed to anticipate future state of affairs have an intrinsic tendency to evolve in full expectations and then in prescriptions. We(More)
The general goal of the paper is to show the normative/deontic nature of conventions. Conventions are traditionally defined as regularity of behavior based on expectations evolved to solve coordination problems [14]. The thesis we defend is that the cognitive attitude of expectations is not only characterized by an anticipatory representation (belief) of a(More)
In this chapter we provide an introductory presentation of normative multi-agent systems (nMAS).<lb>The key idea of the chapter is that any definition of nMAS should preliminarily clarify meaning,<lb>scope, and function of the concept of norm. On account of this idea, we focus on three definitions<lb>and some related requirements for nMAS. For each of such(More)
