Continuous pressure on government budgets, rapid changes in business opportunities and quick technological improvements make today's geo-information market very dynamic. This forces organisations, such as National Mapping Agencies (NMA) and GIS companies, to change the way they generate services and to adopt new working strategies. In this transition,(More)
Organisations in Multi-Agent Systems (MAS) have proven to be successful in regulating agent societies. Nevertheless, changes in agents' behaviour or in the dynamics of the environment may lead to a poor fullment of the system's purposes, and so the entire organisation needs to be adapted. In this paper we focus on endowing the organisation with adaptation(More)
Humans have developed jurisprudence as a mechanism to solve conflictive situations by using past experiences. Following this principle, we propose an approach to enhance a multi-agent system by adding an authority which is able to generate new regulations whenever conflicts arise. Regulations are generated by learning from previous similar situations ,(More)
Normative systems (norms) have been widely proposed as a technique for coordinating multi-agent systems. The automated synthesis of norms for coordination remains an open and complex problem , which we tackle in this paper. We propose a novel mechanism called IRON (Intelligent Robust On-line Norm synthesis mechanism), for the on-line synthesis of norms.(More)
In this paper, we review our Multi-Agent System (MAS) architecture (2-LAMA) proposed to assist existing MAS. This architecture consists of two levels: the conventional MAS system and an additional meta-level in charge of assistance. We illustrate our approach in a Peer-to-Peer sharing network scenario and compare it with the commonly used BitTorrent(More)
The Microblaze is a processor designed by Xilinx that introduces an integrated single precision, IEEE-754 compatible Floating Point Unit (FPU). The MicroBlaze core is a 3-stage pipeline, 32-bit RISC Harvard architecture soft processor core with 32 general purpose registers, ALU, and an instruction set optimized for embedded applications. It supports both(More)
Much previous research has investigated explicit, machine-process-able norms as a means to facilitate coordination in open multi-agent systems. This research can typically be classified as considering either offline design (norms are synthesised at design time) or online design. Online synthesis techniques aim to construct norms for a system while that(More)
Peptides and proteins represent a promissory group of molecules used by the pharmaceutical industry for drug therapy with great potential for development. However, the administration of these molecules presents a series of difficulties, making necessary the exploration of new alternatives like the buccal route of administration to improve drug therapy(More)
In recent years, there has been much research on ontologies for geographic information (GI) services. But to date, focus has been on semantics of data and operations. Much less attention has been given to semantics of quality of GI services. In addressing this gap, this paper proposes an ontology framework for quality of GI services. The framework has an(More)
Adapting organisational structures to maintain an organisation effectiveness under varying circumstances is becoming a hot topic within the agent community. In this paper we present a simulator that we have developed for testing adaptation mechanisms in Peer to Peer scenarios. We regard this service as part of the new generation of services that should be(More)
