Apart from a short description of our Query Track contribution, this report is concerned with the Adaptive Filtering track only. There is a separate report in this volume [1] on the Microsoft Research Cambridge participation in QA track. A number of runs were submitted for the Adaptive Filtering track, on all tasks (adaptive filtering, batch filtering and routing; three separate query sets; two...

A Complex Adaptive System (CAS) is a network of communicating, intelligent agents where each agent adapts its behavior in order to collaborate with other agents to achieve overall system goals. Further, the overall system often exhibits emergent behavior that cannot be achieved by any proper subset of agents alone. A graphical simulation library called Operational Evaluation Modeling for Contex...

Digital Government Infrastructures provide generic functionalities that are used by large numbers of users. Typically, they have no central authority, are governed by networks and contain both emerging and purposefully designed parts. Their use varies over time, and a large number of individuals use them for different purposes. The basic digital government infrastructure has evolved over time a...

This thesis proposal aims to provide a new approach to the study of complex adaptive systems in social sciences through a methodological framework for modeling and simulating these systems like artificial societies. Agent based modeling (ABM) is well fitted for the study of social systems as it focuses on how local interactions among agents generate emergent larger and global social structures ...

An ant colony operates without central control. Each ant uses only local information, mostly odor, and no ant can make global assessments about what needs to be done. No ant gives instructions to another. Through the local decisions of individuals, colonies adjust their behavior to current conditions. An ant decides where to go and what to do based on its recent experience of brief interactions...

By considering definitions of complex adaptive systems, the fundamental features of them are determined. Furthermore, Capra Cognitive Framework for better understanding of living systems is introduced and described. Based on the Santiago Theory of Cognition, Capra Cognitive Framework and Complex Adaptive System features, a model for Biological Complex Adaptive System is proposed and explained. ...

Agent-based Methodology (ABM) is becoming indispensable for the interdisciplinary study of social and economic complex adaptive systems. The essence of ABM lies in the notion of autonomous agents whose behavior may evolve endogenously and can generate and mimic the corresponding complex system dynamics that the ABM is studying. Over the past decade, many Computational Intelligence (CI) methods ...
