The TADA/AMEC joint workshop at AAMAS 2006
Trading Agent Design and Analysis & Agent Mediated Electronic Commerce VIII

Hakodate Japan, May 9 2006

A workshop held in conjunction with the Fifth International Joint Conference on Autonomous Agents and Multi-Agent Systems


The design and analysis of trading agents and electronic trading systems in which they are deployed involves finding solutions to a diverse set of problems, involving individual behaviors, interaction, and colective behavior in the context of trade. A wide variety of trading scenarios and systems, and agent approaches to these, have been studied in recent years. These studies suggest models that support the design and the analysis at the level of the single trading agent and at the level of the multi-agent system.

This workshop will address both the agent level and the system level, combining desing and analysis aspects of electronic trade. The primary goal of this workshop is to continue to bring together novel work from diverse fields as Computer Science, Operations Research, Artificial Intelligence and Distributed Systems that focus on modeling, implementation and evaluation of computational trading agents and institutions.

TADA/AMEC VIII was co-located with the Fifth International Joint Conference on Autonomous Agents and Multiagent Systems (AAMAS'06) and it built on the success of previous workshops of the AMEC and TADA series. 

Topics of interest

All topics related to agents and e-business are welcome. Topics of interest include, but are not restricted to:

  • Distributed (scalable) algorithmic mechanism design

  • Mechanisms for unreliable, dynamic and asynchronous environments

  • Mechanisms for incomplete and/or imperfect information environments

  • Mechanisms for information goods and services

  • Mechanisms for security, privacy, accounting, verification and auditing

  • Distributed (agent and mechanism) learning models

  • Agents strategies in multi-institutional environments

  • Economic and game theoretic specification, design and analysis

  • Bargaining, voting and auction mechanisms

  • Distributed reputation and trusted mechanisms

  • User-Agent interface design

  • Agents that support bidding and negotiation

  • Empirical evaluation of human-agent trading

  • Eliciting human preferences and requirements

  • Simulation and evaluation of properties of novel and complex mechanisms

  • Goods, services, and contract description languages

  • Mechanism description, verification and testing languages

  • Agent mediated electronic system architectures and design principles

  • Implemented agent-mediated electronic-commerce systems

  • Mechanisms for business (supply chains, coalitions, and virtual enterprises)

  • Mechanisms for Internet (Congestion, Routing, Overlay, Peer-to-Peer, ad-hoc networks)

  • Mechanisms for novel applications 


A collection of selected and revised papers from the workshop are available as Springer Verlag LNAI Volume 4452.
