An Analysis Architecture for Communications in Multi-agent Systems

Evaluation tools are significant from the Agent Oriented Software Engineering (AOSE) point of view. Defective designs of communications in Multi-agent Systems (MAS) may overload one or several agents, causing a bullying effect on them. Bullying communications have avoidable consequences, as high response times and low quality of service (QoS). Architectures that perform evaluation functionality must include features to measure the bullying activity and QoS, but it is also recommendable that they have reusability and scalability features. Evaluation tools with these features can be applied to a wide range of MAS, while minimizing designer’s effort. This work describes the design of an architecture for communication analysis, and its evolution to a modular version, that can be applied to different types of MAS. Experimentation of both versions shows differences between its executions

Realizing networks of proactive smart products

The sheer complexity and number of functionalities embedded in many everyday devices already exceed the ability of most users to learn how to use them effectively. An approach to tackle this problem is to introduce ‘smart’ capabilities in technical products, to enable them to proactively assist and co-operate with humans and other products. In this paper we provide an overview of our approach to realizing networks of proactive and co-operating smart products, starting from the requirements imposed by real-world scenarios. In particular, we present an ontology-based approach to modeling proactive problem solving, which builds on and extends earlier work in the knowledge acquisition community on problem solving methods. We then move on to the technical design aspects of our work and illustrate the solutions, to do with semantic data management and co-operative problem solving, which are needed to realize our functional architecture for proactive problem solving in concrete networks of physical and resource-constrained devices. Finally, we evaluate our solution by showing that it satisfies the quality attributes and architectural design patterns, which are desirable in collaborative multi-agents systems

An experimental investigation of profiler and recommender agent in the context of knowledge sharing facilitation

This article aims to collect user satisfaction to prove whether user profiling and recommendation is significant in knowledge sharing facilitation framework. A four-factor evaluation metric to measure the overall performance of the agent based system is used.The evaluation metric consists of three types of analysis which are overlap analysis, weighted responds analysis and responds analysis. The four-factor metric covers the efficiency of user profile built by the agent, the relevance of recommendation, the staff directory and the document repository.The main discussion is on the setting of the experiment and the results of KSFaci performance in the proposed experiment setting.It is concluded that user profiling and recommendation plays a role in knowledge sharing system framework
