Topological theory of intelligent agent networks provides crucial information about the structure of agent distribution over a network. Agent network topologies not only take agent distribution into consideration but also consider agent mobility and intelligence in a network. Current research in the agent network topology area adopts topological theory from(More)
Group awareness has become important in improving the usability of real-time, distributed, collaborative writing systems. However, the current set of implemented awareness mechanisms is insufficient in providing extensive and comprehensive awareness in collaborative authoring. Certainly, current mechanisms, such as telepointers and multiuser scrollbars,(More)
Performance analysis of agent network topologies helps multi-agent system developers to understand the impact of topology on system efficiency and effectiveness. Appropriate topology analysis enables the adoption of suitable frameworks for the specific multi-agent systems. In this paper, we propose a novel hybrid topology for distributed multi-agent(More)
Despite the critical need for an open architecture in decision support system (DSS) design, present DSS architectural design are unable to provide a fundamental solution to enhance the flexibility, connectivity, compatibility, and intelligence of a DSS. In this paper, we present a novel multi-agent-based architecture for DSS, called agent-based open(More)
Social recommendation methods, often taking only one kind of relationship in social network into consideration, still faces the data sparsity and cold-start user problems. This paper presents a novel recommendation method based on multi-relational analysis: first, combine different relation networks by applying optimal linear regression analysis, and then,(More)
