Open Agent System platform based on High Level Architecture is firstly proposed to support the application involving heterogeneous agents. The basic idea is to develop different wrappers for different agent systems, which are wrapped as federates to join a federation. The platform is based on High Level Architecture and the advantages for this open standard are naturally inherited, such as syst...

ACORN (Agent-based Community Oriented Routing Network) is a distributed multi-agent architecture for the search, distribution and management of information in networks. ACORN utilizes the concept of ‘information as agent’ together with an application of Stanley Milgram’s Small World Problem (the idea of Six Degrees of Separation) in order to route individual items of information around networks...

The computational needs of the Intelligent Room – while not unique – were not satisfied by any pre-existing software systems or programming environments. We wanted the Intelligent Room’s software infrastructure to be persistent, robust, and dynamically reconfigurable. We needed the ability to modify (or even introduce) individual components without bringing the whole system down, and we wanted ...

In this paper we investigate the model-checking problem of pushdown multi-agent systems for ATL specifications. To this aim, we introduce pushdown game structures over which ATL formulas are interpreted. We show an algorithm that solves the addressed model-checking problem in 3ExpTime. We also provide a 2ExpSpace lower bound by showing a reduction from the word acceptance problem for determinis...

The large amount of pages in Websites is a problem for users who waste time looking for the information they really want. Knowledge about users’ previous visits may provide patterns that allow the customization of the Website. This concept is known as Adaptive Website: a Website that adapts itself for the purpose of improving the user's experience. Some Web Mining algorithms have been proposed ...

Mobile Agents technology opens up new avenues in personalizing and customizing the web experience of users. It provides new possibilities for deploying distributed applications using existing web infrastructure. One of the reasons why mobile agents are not yet popular on the web is due to the lack of an easily deployable framework that would facilitate their existence. Existing mobile agent sys...

This paper presents a multi-agent system (MAS) that implements a recommender system, essentially using collaborative filtering techniques. The design of the MAS is flexible to support the implementation of different filtering strategies and to control the global behavior of the system and its users. It has been applied in the PSI3 project to implement a personalized information dissemination se...
