Social Mental Shaping: Modelling the Impact of Sociality on Autonomous Agents' Mental States
This paper presents a framework that captures how the social nature of agents that are situated in a multi-agent environment impacts upon their individual mental states. Roles and relationships provide an abstraction upon which we develop the notion of social mental shaping. This allows us to extend the standard Belief-Desire-Intention model to account for how common social phenomena (e.g. cooperation, collaborative problem-solving and negotiation) can be integrated into a unified theoretical perspective that reflects a fully explicated model of the autonomous agent's mental state

Embodied cognition and temporally extended agency
According to radical versions of embodied cognition, human cognition and agency should be explained without the ascription of representational mental states. According to a standard reply, accounts of embodied cognition can explain only instances of cognition and agency that are not ārepresentation-hungryā. Two main types of such representation-hungry phenomena have been discussed: cognition about āthe absentā and about āthe abstractā. Proponents of representationalism have maintained that a satisfactory account of such phenomena requires the ascription of mental representations. Opponents have denied this. I will argue that there is another important representation-hungry phenomenon that has been overlooked in this debate: temporally extended planning agency. In particular, I will argue that it is very difficult to see how planning agency can be explained without the ascription of mental representations, even if we grant, for the sake of argument, that cognition about the absent and abstract can. We will see that this is a serious challenge for the radical as well as the more modest anti-representationalist versions of embodied cognition, and we will see that modest anti-representationalism is an unstable position
A deliberative model for self-adaptation middleware using architectural dependency
A crucial prerequisite to externalized adaptation is an understanding of how components are interconnected, or more particularly how and why they depend on one another. Such dependencies can be used to provide an architectural model, which provides a reference point for externalized adaptation. In this paper, it is described how dependencies are used as a basis to systems' self-understanding and subsequent architectural reconfigurations. The approach is based on the combination of: instrumentation services, a dependency meta-model and a system controller. In particular, the latter uses self-healing repair rules (or conflict resolution strategies), based on extensible beliefs, desires and intention (EBDI) model, to reflect reconfiguration changes back to a target application under examination
Alert-BDI: BDI Model with Adaptive Alertness through Situational Awareness
In this paper, we address the problems faced by a group of agents that
possess situational awareness, but lack a security mechanism, by the
introduction of a adaptive risk management system. The Belief-Desire-Intention
(BDI) architecture lacks a framework that would facilitate an adaptive risk
management system that uses the situational awareness of the agents. We extend
the BDI architecture with the concept of adaptive alertness. Agents can modify
their level of alertness by monitoring the risks faced by them and by their
peers. Alert-BDI enables the agents to detect and assess the risks faced by
them in an efficient manner, thereby increasing operational efficiency and
resistance against attacks.Comment: 14 pages, 3 figures. Submitted to ICACCI 2013, Mysore, Indi
Acting Without Me: Corporate Agency and the First Person Perspective
In our book The Inessential Indexical we argue that the various theses of essential indexicality all fail. Indexicals are not essential, we conclude. One essentiality thesis we target in the third chapter is the claim that indexical attitudes are essential for action. Our strategy is to give examples of what we call impersonal action rationalizations , which explain actions without citing indexical attitudes. To defeat the claim that indexical attitudes are essential for action, it suffices that there could be even one successful impersonal action rationalization. In what follows we bolster our case against an essential connection between action and the de se (or indexicality), first by developing a range of new action models and secondly by responding to challenges from Dilip Ninan, Stephan Torre, and JosĆ© Luis BermĆŗdez
Character and theory of mind: an integrative approach
Traditionally, theories of mindreading have focused on the representation of beliefs and desires. However, decades of social psychology and social neuroscience have shown that, in addition to reasoning about beliefs and desires, human beings also use representations of character traits to predict and interpret behavior. While a few recent accounts have attempted to accommodate these findings, they have not succeeded in explaining the relation between trait attribution and belief-desire reasoning. On my account, character-trait attribution is part of a hierarchical system for action prediction, and serves to inform hypotheses about agentsā beliefs and desires, which are in turn used to predict and interpret behavior
An Analysis of the Notion of Need for the Representation of Public Services
Many Public Administrations structure their services around the notion
of usersā need. However, there is a gap between private, subjectively perceived
needs (self-attributed) and needs that are attributed by PA to citizens (heteroattributed).
Because of the gap, citizensā needs are often only partially satisfied by
PAs services. This gap is in part due to the fact that the meaning of the word āneedā
is ambiguous and full of antinomic nuances. The purpose of this paper is to formulate
a definition of āneedā suitable for citizensā needs management with respect to
PAās services offering, and to provide an accurate ontological analysis of the notion
of āneedā and the network of concepts that relate to it
From SMART to agent systems development
In order for agent-oriented software engineering to prove effective it must use principled notions of agents and enabling specification and reasoning, while still considering routes to practical implementation. This paper deals with the issue of individual agent specification and construction, departing from the conceptual basis provided by the SMART agent framework. SMART offers a descriptive specification of an agent architecture but omits consideration of issues relating to construction and control. In response, we introduce two new views to complement SMART: a behavioural specification and a structural specification which, together, determine the components that make up an agent, and how they operate. In this way, we move from abstract agent system specification to practical implementation. These three aspects are combined to create an agent construction model, actSMART, which is then used to define the AgentSpeak(L) architecture in order to illustrate the application of actSMART
