    Summary form only given. Wikipedia is a goldmine of information; not just for its many readers, but also for the growing community of researchers who recognize it as a resource of exceptional scale and utility. It represents a vast investment of manual effort and judgment: a huge, constantly evolving tapestry of concepts and relations that is being applied to a host of tasks. This talk focuses on ...

    Security at major locations of economic or political importance or transportation or other infrastructure is a key concern around the world, particularly given the threat of terrorism. Limited security resources prevent full security coverage at all times; instead, these limited resources must be deployed intelligently taking into account differences in priorities of targets requiring security cov...

    Summary form only given. Classical information retrieval is based around a user having an information need, formulated as a query, and a system which matches the query against 'documents', retrieving those most likely to be relevant. In some applications there are challenges because the 'documents' are not discrete objects but highly inter-connected, and IR research has for decades developed model... View full abstract»

  • Issues on Preference-Modelling and Personalization in Information Retrieval

    Publication Year: 2010, Page(s): 4
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (223 KB)

    In recent years there has been a great deal of research about personalization in information access. The main issue is to improve the quality of search by producing user-tailored results related to specific user needs. In this context two key research problems concerns how to model user preferences, and how to exploit them in effective personalisation processes. This talk will address the above pr...

  • Why Robots are More Than Just Agents

    Publication Year: 2010, Page(s): 5
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (220 KB) | HTML iconHTML

    Summary form only given. Robots are more than just agents because they have a physical body and interact with the real world through their sensors and actuators. They also have limited power supply and often limited communications capabilities. In the talk we will explore how this affects the design of robot systems and address open challenges in design, validation, and performance evaluation of r... View full abstract»

  • An Agent-Based Modeling Approach to Investigate Emergent Patterns in Ecological Systems

    Publication Year: 2010, Page(s):6 - 13
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1654 KB) | HTML iconHTML

    Due to its suitability, agent-based modeling is more and more often being applied in the domain of Ecology. The development of an agent-based model for the Ecological domain is however very difficult. Usually, many parameters need to be set to appropriate values and such values are not always available through fieldwork or in literature. This paper presents a generic approach to develop agent-base... View full abstract»

  • Towards Efficient Equilibria of Combinations of Network-Formation and Interaction Strategies

    Agents in networks have two strategic choices: They can forward/process incoming service requests - or not, and they can establish additional contacts and maintain or terminate existing ones. In other words, an agent can choose both an action-selection and a link-selection strategy. So far, it is unclear which equilibria exist in such settings. We show that there are the following equilibria: Firs... View full abstract»

    Within service-oriented architectures, components need to discover and interact with suitable services, which in turn can be mapped to particular subtasks. Similarly, in online social communities users may wish to discover information related to a particular interest that matches their personal preferences. These tasks are difficult when the number of available resources to select from is large, a... View full abstract»

  • Nash Welfare Allocation Problems: Concrete Issues

    Publication Year: 2010, Page(s):32 - 39
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (588 KB) | HTML iconHTML

    The allocation of m resources between n agents is an AI problem with a great practical interest for automated trading. The general question is how to configure the behavior of bargaining agents to induce a socially optimal allocation. The literature contains many proposals for calculating a social welfare but the Nash welfare seems to be the one which has the most interesting properties for a fair... View full abstract»

    When its human operator cannot continuously supervise (much less teleoperate) an agent, the agent should be able to recognize its limitations and ask for help when it risks making autonomous decisions that could significantly surprise and disappoint the operator. Inspired by previous research on making exploration-exploitation tradeoff decisions and on inverse reinforcement learning, we develop Ex... View full abstract»

    Distributed Task Assignment is a convenient abstraction for load-balancing applications, workflow systems or supply-chain management. The topological features of such task networks are far from random but instead resemble that of small-worlds and scale-free networks. The agent's interaction is accordingly prescribed by this network structure. Simulating decentralised optimisation algorithms using ... View full abstract»

    In this paper, we present our analysis of trajectories for understanding the behaviour of reactive robots in a patrol task. Reactive robots are considered as one of the main applications of agent technologies and are hence one of the major resources of new challenges for the technologies. The task of our 4 real robots, each of which is equipped with 3 infrared sensors and an identical controller, ... View full abstract»

  • Particle Swarm Optimization Based Hierarchical Agglomerative Clustering

    Clustering- an important data mining task, which groups the data on the basis of similarities among the data, can be divided into two broad categories, partitional clustering and hierarchal. We combine these two methods and propose a novel clustering algorithm called Hierarchical Particle Swarm Optimization (HPSO) data clustering. The proposed algorithm exploits the swarm intelligence of cooperati... View full abstract»

  • Enhancing Cultural Learning under Environmental Variability Using Layered Heterogeneous Sociometry-Based Networks

    Our goal in this paper was to investigate the impact that the addition of a Heterogeneous layered Social network will have on problem solving ability of a Cultural system. The synergisms of the emergent swarms in the population and belief spaces are affected by training the social network on a dynamic but recurring pattern weaved by our social influence function. The cultural system has adjusted i... View full abstract»

  • A Multi-heuristic Cooperative Ant Colony System for Optimizing Elimination Ordering of Bayesian Networks

    To solve the problem of searching for an optimal elimination ordering of Bayesian networks, a novel effective heuristic, MinSum Weight, and an ACS approach incorporated with multi-heuristic mechanism are proposed. The ACS approach named MHC-ACS utilizes a set of heuristics to direct the ants moving in the search space. The cooperation of multiple heuristics helps ants explore more regions. Moreove...

    The performance of many emerging communication paradigms depend on high levels of cooperation amongst the peers in the network. Although an individual's best strategy may be to selfishly consume resources without reciprocation, the optimal social performance requires agents in the network to behave in an altruistic manner. This paper considers a P2P data dissemination scenario, and applies an auto... View full abstract»
