The Eleventh International Workshop on

Agent Mediated Electronic Commerce

(AMEC 2009)

May 12, 2009

Budapest, Hungary

Organization & Location

The eleventh AMEC workshop is held in conjunction with AAMAS-2009 (the Eighth International Joint Conference on Autonomous Agents and Multiagent Systems), in Budapest, Hungary. It will take place on May 12, 2009, preceding AAMAS 2009.

Aims and Focus

The design and analysis of electronic commerce systems in which agents are deployed involves finding solutions to a large and diverse array of problems, concerning individual agent behaviors, interaction, and collective behavior. A wide variety of electronic commerce 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 both the level of the single agent and the level of the multi-agent system.

This workshop will address both the agent level and the system level, combining design and analysis aspects of electronic commerce. The primary goal of this workshop is to continue to bring together novel work from diverse fields as Computer Science, Game Theory, Economics, Artificial Intelligence and Distributed Systems that focus on modeling, implementation and evaluation of computational trading agents and institutions. We particularly encourage work that addresses the computational and practical aspects of agent-mediated electronic commerce along the following (non-limiting) topics:

·         Agency and contract theory in e-commerce

·         AI and autonomous agent systems in e-commerce

·         Algorithmic mechanism design

·         Auction and negotiation technology

·         Automated shopping, trading, and contract management

·         Computational aspects of economics, game theory, and voting

·         Experience with e-commerce systems and markets

·         Formation of supply chains, coalitions, and virtual enterprises

·         Languages for describing agents, goods, services, and contracts

·         Learning and Intelligence aspects of trading agents

·         Peer-to-peer, grid, and other open distributed systems

·         Prediction/information markets

·         Preferences and decision theory

·         Recommendation, reputation, and trust systems

·         Software and systems requirements, architectures, and performance

Furthermore, this workshop will also welcome position papers discussing central non-technical issues of agent-mediated electronic commerce. For instance:

·         Business models and markets for AMEC

·         Novel applications

·         Past and future of AMEC technologies

·         Technical, economic, social and policy opportunities and challenges of AMEC
