Semantic Web services are self describing programs that can be searched, understood and used by other programs. Despite the advantages Semantic Web services provide, specially for building agent based systems, there is a need for mechanisms to enable agents to discover Semantic Web services. This paper describes an extension of the MoviLog agent platform for searching Web services taking into a...

This paper presents a conceptual model that adds mental states, capable of dealing with social elements, to BDI architectures. It has long been recognized that social elements enhance multi-agent performance. Ideas for extending BDI architectures to incorporate norms, values and obligations are presented. Norms and values endow multi-agent systems with social attributes thereby facilitating the...

A semantic enabled multi-agent architecture for solving non-linear equations systems by using a service oriented approach is proposed. The service oriented approach allows us to access already implemented methods for solving complex mathematical problems. The semantic descriptions of these services provide support for intelligent agents. The proposed architecture is a framework with two extensi...

Determination of the challenges extension agents are facing leads to increased efficiency and effectiveness services. This study assessed in Iraq facing. 100 were selecting, face-to-faces an interview with a pre-tested structured questionnaire was used collect data. The revealed that fifty-three respondents faced medium challenges. most important were; low farmer ratio, lack participation, disp...

This paper presents an agent-based model of disaggregated economic systems with endogenous growth features named Lagom GeneriC. This model is thought to represent a proof of concept that dynamically complete and highly disaggregated agent-based models allow to model economies as complex dynamical systems. It is used here for “theory generation”, investigating the extension to a framework with c...

Mobile agents gained immense attraction as a new programming concept for implementing distributed applications. However, up to now mobile agent programming has been mainly technology driven, with a focus on the implementation of mobile agent platforms and only small programming applications. In this work, we present an extension of the standard UML that provides language concepts for modeling m...

This paper describes an agent-based architecture designed to provide automation support for users who perform information processing tasks using a collection of distributed and disparate software tools and on-line resources. The architecture extends previous work on agent-based software interoperability. The unique features of the information processing domain compared to distributed informatio...

Anomaly detection, as performed by the COVER tool, has proven to be a useful method for verification of knowledge-based systems. The increasing development of distributed knowledge-based systems based upon the multi-agent architecture demands techniques for the verification of these systems. This paper describes the COVERAGE too1 -an extension of COVER designed to perform anomaly detection on m...

This paper reports progress in realizing human-agent argumentation, which we argue will be part of future Computer-Supported Collaborative Argumentation (CSCA) tools. With a particular interest in argument mapping, we present two investigations demonstrating how a particular agent-oriented language and architecture can augment CSCA: (i) the use of the IBIS formalism enabling Brahms agents to si...

Based on two intuitions – (i) event-driven systems and multi-agent systems are two computational paradigms that are amenable of a coherent interpretation within a unique conceptual framework; (ii) integrating the two simulation approaches can lead to a more expressive and powerful simulation framework – we propose a computational model integrating Discrete-Event Simulation (DES) and Multi-Agent...
