This book constitutes the thoroughly refereed post-proceedings of the 4th International Workshop on Agent-Mediated Electronic Commerce, AMEC 2002, held in Bologna, Italy in July 2002 during the AAMAS 2002 conference. The 20 revised full papers presented together with an introductory survey by the volume editors were carefully selected and improved during two rounds of reviewing and revision. The book gives a unique overview of the state of the art of designing mechanisms and systems for agent-mediated e-commerce- The papers are organized in topical sections on electronic auctions, negotiations, and electronic markets.
This volume contains 13 thoroughly refereed and revised papers detailing recent advances in research on trading agents, negotiating agents, dynamic pricing, and auctions. They were originally presented at the 10th International Workshop on Agent-Mediated Electronic Commerce (AMEC 2008) collocated with AAMAS 2008 in Estoril, Portugal, or the 6th Workshop on Trading Agent Design and Analysis (TADA 2008) collocated with AAAI 2008 in Chicago, IL, USA. The papers originating from AMEC 2008 address agent modeling and multi-agent problems in the context of e-negotiations and e-commerce. The TADA papers stem from the effort to design scenarios where trading agents and market designers can be pitched against each other in applications from supply chain management and procurement. They are all characterized by interdisciplinary research combining fields such as artificial intelligence, distributed systems, game theory, and economics.
The Internet is spawning many new markets and electronic commerce is changing many market conventions. Not only are old commercial practices being adapted to the new conditions of immediacy brought forth by the global networks, but new products and services, as well as new practices, are beginning to appear. There is already ample evidence that agent-based technologies will be crucial for these - velopments. However many theoretical, technological, sociological, and legal - pects will need to be addressed before such opportunities become a significant reality. In addition to streamlining traditional transactions, agents enable new types of transactions. For example, the elusive one-to-one marketing becomes more of a - ality when consumer agents capture and share (or sell) consumer demographics. Prices and other transaction dimensions need no longer to be fixed; selling agents can dynamically tailor merchant offerings to each consumer. Economies of scale become feasible in new markets when agents negotiate on special arbitration c- tracts. Dynamic business relationships will give rise to more competitively agile organizations. It is these new opportunities combined with substantial reduction in transaction costs that will revolutionize electronic commerce.
This book constitutes the thoroughly refereed post-proceedings of the joint International Workshops on Trading Agent Design and Analysis, TADA 2006, and on Agent Mediated Electronic Commerce, AMEC VIII 2006, held in Hakodate, Japan. The papers address a mix of both theoretical and practical issues in trading agent design and technologies, theoretical and empirical evaluation of strategies in complex trading scenarios as well as mechanism design.
In this book we present a collection of papers around the topic of Agent-Mediated Electronic Commerce. Most of the papers originate from the third workshop on Agent{Mediated Electronic Commerce held in conjunction with the Autonomous Agents conference in June 2000. After two previous workshops, one during the Autonomous Agents conference in 1998 in Minneapolis and the second one in conjunction with the International Joint Conference On Arti cial Intelligence in 1999, this workshop continued the tradition of the previous ones by setting the scene for the assessment of the challenges that Agent-Mediated Electronic Commerce faces as well as the opportunities it creates. By focusing on age- mediated interactions, specialists from di erent disciplines were brought together who contribute theoretical and application perspectives in the narrowly focused topic that nevertheless involves wide ranging concerns such as: agent architec- res, institutionalization, economic theory, modeling, legal frameworks and policy guidelines. The main topics for the workshop were: { Electronic negotiation models for agents { Formal issues for agents that operate in electronic market places { Virtual trading institutions and platforms { Trading strategies for interrelated transactions (respectively auctions) The workshop received 12 submissions of which 7 were selected for publication in this volume. Although the number of submissions was less then expected for an important area like agent-mediated electronic commerce there is no reason to worry that this area does not get enough attention from the agent community.
This book constitutes the thoroughly refereed post-proceedings of the 7th International Workshop on Agent-Mediated Electronic Commerce, AMEC VII 2005, held in Utrecht, Netherlands in July 2005, as part of AAMAS 2005, and the third Workshop on Trading Agent Design and Analysis, TADA 2005, held in Edinburgh, UK in August 2005, in the course of the IJCAI 2005 conference meetings. The seven revised full AMEC 2005 papers presented were carefully selected.
Complex Automated Negotiations have been widely studied and are becoming an important, emerging area in the field of Autonomous Agents and Multi-Agent Systems. In general, automated negotiations can be complex, since there are a lot of factors that characterize such negotiations. These factors include the number of issues, dependency between issues, representation of utility, negotiation protocol, negotiation form (bilateral or multi-party), time constraints, etc. Software agents can support automation or simulation of such complex negotiations on the behalf of their owners, and can provide them with adequate bargaining strategies. In many multi-issue bargaining settings, negotiation becomes more than a zero-sum game, so bargaining agents have an incentive to cooperate in order to achieve efficient win-win agreements. Also, in a complex negotiation, there could be multiple issues that are interdependent. Thus, agent's utility will become more complex than simple utility functions. Further, negotiation forms and protocols could be different between bilateral situations and multi-party situations. To realize such a complex automated negotiation, we have to incorporate advanced Artificial Intelligence technologies includes search, CSP, graphical utility models, Bays nets, auctions, utility graphs, predicting and learning methods. Applications could include e-commerce tools, decision-making support tools, negotiation support tools, collaboration tools, etc. In this book, we solicit papers on all aspects of such complex automated negotiations in the field of Autonomous Agents and Multi-Agent Systems. In addition, this book includes papers on the ANAC 2010 (Automated Negotiating Agents Competition), in which automated agents who have different negotiation strategies and implemented by different developers are automatically negotiate in the several negotiation domains. ANAC is one of real testbeds in which strategies for automated negotiating agents are evaluated in a tournament style.
This book constitutes the refereed proceedings of the 7th International Conference on Electronic Commerce and Web Technologies, EC-Web 2006, held in conjunction with DEXA 2006. The book presents 24 revised full papers together with 1 invited talk, organized in topical sections on recommender systems, business process/design aspects, mobile commerce, security and e-payment, Web services computing/semantic Web, e-negotiation and agent mediated systems, and issues in Web advertising.
This book constitutes the thoroughly refereed post-conference proceedings of the 9th International Workshop on Agent-Mediated Electronic Commerce, AMEC IX, co-located with the Sixth International Joint Conference on Autonomous Agents and Multiagent Systems, AAMAS 2007, held in Honolulu, Hawai, in May 2007, and the 5th Workshop on Trading Agent Design and Analysis, TADA 2007, co-located with the Twenty-Second AAAI Conference on Artificial Intelligence, AAAI 2007, held in Vancouver, Canada, in July 2007. This volume presents 15 carefully revised and selected papers from these workshops. The primary and complementary goal of both workshops was to continue to bring together novel work from diverse fields on modeling, implementation and evaluation of computational trading institutions and/or agent strategies. The papers originating from AMEC focus on a large variety of issues on auctions, negotiation, and strategic behavior in electronic marketplaces. The papers originating from TADA reflect the effort of the community to design scenarios where trading agent designers and market designers can be pitched against one another.
