  3. INTRODUCTION

  4. Data mining & multiagent research group at UTS • Cross disciplinary researchers interacting at the group • Integrated research of data mining and multi-agent system • http://datamining.it.uts.edu.au • Real-world applications of the integration • Capital markets • F-Trade

  5. Agents as a new computing paradigm for complex problems • Strengths • Analyze and understand complex systems • Deal with nonfunctional requirements • Handle social complexity such as distribution, dynamics, interaction, evolution, self-organization • Build flexible infrastructure • Weaknesses • Lack machine learning capability • Lack in-depth analytics • Lack knowledge representation

  6. Data mining and knowledge discovery as an effective tool for in-depth analysis • Strengths • Deep data analysis • Deep knowledge discovery • Weaknesses • Nothing related to system infrastructure • Deal with social complexity such as distribution, dynamics

  7. Bilateral enhancement of agents and data mining by the integration • Agents can enrich data mining • Data mining can improve agents • Mutual enhancement: integration between data mining and multi-agent system
