This paper proposes an agent programming language called agentSpeak(l). This new language allows agent programs (1) to effectively perform while having incomplete knowledge of the environment. (2) to detect no-longer possible goals and re-plan these goals correspondingly. and (3) to behave reactively to changes of environment. Specifically, agentSpeak(l) uses default theory as agent belief theory, agent always act with preferred default extension at current time point (i.e. preference may changes over time). A belief change operator for default theory is also provided to assist agent program to update its belief theory. Like other BDI agent programming languages, agentSpeak(l) uses semantics of transitional system. It appears that the language is well suited for intelligent applications and high level control robots, which are required to perform in highly dynamic environment.

The Belief-Desire-Intention (BDI) model is well suited for describing an agent's mental state. To model human reasoning with uncertainty and imprecision, fuzzy logic have been employed to represent beliefs for BDI agents in our previous work. In order that the BDI agents are more and more suitable for modelling our real world, a BDI agent programming language with fuzzied-belief based on a existing BDI agent programming language is developed in this paper. The new language is more flexible and human-like compared to non-fuzzy based BDI agent language in the real world applications. Particularly, it provides a more reasonable planning selection mechanism. The reasoning capability of the previous BDI language is improved due to the work in this paper.

EXPERT SYSTEMS WITH APPLICATIONS 2016年 43卷 131-141页

Emotions are the integral part of human cognitive processes. To make an artificial agent more human-like, agent programming languages should be able to model the emotion based artificial agent. To address the need of incorporation of emotions in agent programming languages, recently, extension of 2APL with emotions is proposed by the researchers. However, they were unable to program complex emotion dynamics, due to integration complexities associated with advanced emotive models. They have modified 2APL by designing E-rules, coping rules, and an interface-Affect Engine. The Affect Engine establishes a link between the modified 2APL and a rather simpler emotion model, ALMA. Here, we propose the programming constructs for integrating an advanced yet rule based emotion model, EMIA, in line with the 2APL. The fusion of both has been carried out by redefining the syntax, semantics and deliberation cycle of the 2APL. These redefinitions lead to the required transformation in the dialect cycle;from the sense-interpret-act to percept-appraisal-elicitation-act. The proposed novel programming constructs and pragmatics enable flexible and adaptive emotional behavioral modeling for an expressive autonomous agent with domain independent emotion elicitation, emotion regulation and emotion transition processes. The simulation results show high believability in the emotions expressed by the agent while responding to the real life scenarios. (C) 2015 Elsevier Ltd. All rights reserved.

In this paper, we give an operational and denotational semantics for a meta-language of the 3APL agent programming language. With this meta-language, various 3APL interpreters can be programmed. We prove equivalence of the operational and denotational semantics. Furthermore, we give an operational semantics for object-level 3APL. Using this semantics, we relate the 3APL meta-language to object-level 3APL by providing a specific interpreter, the semantics of which will prove to be equivalent to object-level 3APL.

Normative systems offer a means to govern agent behaviour in dynamic open environments. Under the governance, agents themselves must be able to reason about compliance with state-or event-based norms (or both) depending upon the formalism used. This paper describes how norm awareness enables a BDI agent to exhibit norm compliant behaviour at run-time taking into account normative factors. To this end, we propose N-Jason, a run-time norm compliant BDI agent framework supporting norm-aware deliberation as well as run-time norm execution mechanism, through which new unknown norms are recognised and bring about the triggering of plans. To be able to process a norm such as an obligation, the agent architecture must be able to deal with deadlines and priorities, and choose among the plans triggered by a particular norm. Consequently, we extend the syntax and the scheduling algorithm of agentSpeak(RT) to operate in the context of Jason/agentSpeak(L) and provide 'real-time agency', which we explain through a detailed examination of the operational semantics of a single reasoning cycle.

Current BDI agent frameworks often lack necessary modularity, scalability and are hard to integrate with non-agent applications. This paper reports ongoing research on Light Jason, a multi-agent BDI framework based on agentSpeak(L), fine-tuned to concurrent plan execution in a distributed framework;LightJason aims at efficient and scalable integration with existing platforms. We state requirements for BDI agent languages and corresponding runtime systems, and present the key concepts and initial implementation of LightJason in the light of these requirements. Based on a set of requirements derived for scalable, modular BDI frameworks, the core contribution of this paper is the definition of a formal modular grammar for agentSpeak(L++), a modular extension of agentSpeak(L), and its underlying scalable runtime system. A preliminary validation of LightJason is given by means of an example evacuation scenario, an experimental analysis of the runtime performance, and a qualitative comparison with the Jason platform.

Normative systems offer a means to govern agent behaviour in dynamic open environments. Under the governance, individual agents themselves must reason about compliance with state-or event-based norms (or both) depending upon the formalism used. This paper describes how norm awareness enables a BDI agent to exhibit norm compliant behaviour at run-time taking into account normative factors. To this end, we propose N-Jason, a run-time norm compliant BDI agent framework which supports norm-aware deliberation as well as a run-time norm execution mechanism, through which previously unknown norms are recognized and bring about the triggering of plans.

作者： Miyashita, T NEC Corp Ltd Human Media Res Labs Tokyo Japan

The author gives an overview of intelligent and autonomous software, also called agents, from a technological viewpoint. In addition, he introduces several concrete agents that have been developed by NEC Corporation. agent technology is divided into three layers: agent programming languages, agent platforms and applications. Each layer possesses particular technical keywords, for example, distributed object programming in the language layer, agent communication protocols and architecture in the platform layer, and agent collaboration models in the application layer. NEC Corporation has been conducting research and development in every layer in order to produce convenient and high-level intelligent software for our customers. Our agents play the role of an office secretary, an intelligent communication controller, a certain kind of project manager or a software robot for Web exploration.
