    An Investigation of the Negotiation Domain for Electronic Commerce Information Systems

    Get PDF
    To support fully automatic business cycles, information systems for electronic commerce need to be able to conduct negotiation automatically. In recent years, a number of general frameworks for automated negotiation have been proposed. Application of such frameworks in a specific negotiation situation entails selecting the proper framework and adapting it to this situation. This selection and adaptation process is driven by the specific characteristics of the situation. This paper presents a systematic investigation of there characteristics and surveys a number of frameworks for automated negotiation

    Efficient Methods for Automated Multi-Issue Negotiation: Negotiating over a Two-Part Tariff

    No full text
    In this article, we consider the novel approach of a seller and customer negotiating bilaterally about a two-part tariff, using autonomous software agents. An advantage of this approach is that win-win opportunities can be generated while keeping the problem of preference elicitation as simple as possible. We develop bargaining strategies that software agents can use to conduct the actual bilateral negotiation on behalf of their owners. We present a decomposition of bargaining strategies into concession strategies and Pareto-efficient-search methods: Concession and Pareto-search strategies focus on the conceding and win-win aspect of bargaining, respectively. An important technical contribution of this article lies in the development of two Pareto-search methods. Computer experiments show, for various concession strategies, that the respective use of these two Pareto-search methods by the two negotiators results in very efficient bargaining outcomes while negotiators concede the amount specified by their concession strategy

    A Rule-driven Approach for Defining the Behavior of Negotiating Software Agents

    Get PDF
    One problem with existing agent-mediated negotiation systems is that they rely on ad hoc, static, non-adaptive, and hardcoded schemes to represent the behaviour of agents. This limitation is probably due to the complexity of the negotiation task itself. Indeed, while negotiating, software (human) agents face tough decisions. These decisions are based not only on the information made available by the negotiation server, but on the behaviour of the other participants in the negotiation process as well. The information and the behaviour in question are constantly changing and highly uncertain. In the first part of the paper, we propose a rule-driven approach to represent, manage and explore negotiation strategies and coordination information. For that, we divide the behaviour of negotiating agents into protocols, strategies and coordination. Among the many advantages of the proposed solution, we can cite the high level of abstraction, the closeness to human understanding, the versatility, and the possibility to modify the agents' behaviour during the negotiation process. To validate our solution, we ran many agent tournaments, and used the rule-driven approach to implement bidding strategies that are common in the English and Dutch auctions. We also implemented simple coordination schemes across several auctions. The ongoing validation work is detailed and discussed in the second part of the paper. Un des inconvĂ©nients qu'on retrouve frĂ©quemment dans les systĂšmes de nĂ©gociation par agents est qu'ils reposent sur des schĂ©mas ad-hoc, non adaptatifs et figĂ©s dans le code pour reprĂ©senter le comportement des agents. Cette limitation est probablement due Ă  la complexitĂ© de l'activitĂ© de nĂ©gociation elle-mĂȘme. En effet, au cours de la nĂ©gociation, les agents logiciels (humains) ont des dĂ©cisions difficiles Ă  prendre. Ces dĂ©cisions ne sont pas seulement basĂ©es sur l'information disponible sur le serveur de nĂ©gociation, mais aussi sur le comportement des autres participants durant le processus de nĂ©gociation. L'information et le comportement en question changent constamment et sont trĂšs incertains. Dans la premiĂšre partie de l'article, nous proposons une approche Ă  base de rĂšgles pour reprĂ©senter, gĂ©rer et explorer les stratĂ©gies de nĂ©gociation ainsi que l'information de coordination. Parmi les nombreux avantages de la solution proposĂ©e, on peut citer le haut niveau d'abstraction, la proximitĂ© avec la comprĂ©hension humaine, la souplesse d'utilisation et la possibilitĂ© de modifier le comportement des agents durant le processus de nĂ©gociation. Pour valider notre solution, nous avons effectuĂ© plusieurs tournois entre agents et utilisĂ© l'approche Ă  base de rĂšgles pour implĂ©menter des stratĂ©gies simples applicables Ă  l'enchĂšre anglaise et Ă  l'enchĂšre hollandaise. Nous avons aussi implĂ©mentĂ© des schĂ©mas simples de coordination impliquant plusieurs enchĂšres. Le travail de validation, en cours, est dĂ©taillĂ© et discutĂ© dans la seconde partie de l'article.e-negotiation, online auction, software agent, negotiation strategy, coordination, rule-based system, rule engine, NĂ©gociation Ă©lectronique, enchĂšres en ligne, agents logiciels, stratĂ©gie de nĂ©gociation, coordination, systĂšme Ă  base de rĂšgles, moteur de rĂšgles

    Privacy-Preserving Trust Management Mechanisms from Private Matching Schemes

    Full text link
    Cryptographic primitives are essential for constructing privacy-preserving communication mechanisms. There are situations in which two parties that do not know each other need to exchange sensitive information on the Internet. Trust management mechanisms make use of digital credentials and certificates in order to establish trust among these strangers. We address the problem of choosing which credentials are exchanged. During this process, each party should learn no information about the preferences of the other party other than strictly required for trust establishment. We present a method to reach an agreement on the credentials to be exchanged that preserves the privacy of the parties. Our method is based on secure two-party computation protocols for set intersection. Namely, it is constructed from private matching schemes.Comment: The material in this paper will be presented in part at the 8th DPM International Workshop on Data Privacy Management (DPM 2013

    An Evolutionary Learning Approach for Adaptive Negotiation Agents

    Get PDF
    Developing effective and efficient negotiation mechanisms for real-world applications such as e-Business is challenging since negotiations in such a context are characterised by combinatorially complex negotiation spaces, tough deadlines, very limited information about the opponents, and volatile negotiator preferences. Accordingly, practical negotiation systems should be empowered by effective learning mechanisms to acquire dynamic domain knowledge from the possibly changing negotiation contexts. This paper illustrates our adaptive negotiation agents which are underpinned by robust evolutionary learning mechanisms to deal with complex and dynamic negotiation contexts. Our experimental results show that GA-based adaptive negotiation agents outperform a theoretically optimal negotiation mechanism which guarantees Pareto optimal. Our research work opens the door to the development of practical negotiation systems for real-world applications

Copyright @ 2012 Elsevier B.V.This paper proposes an agent based mobile negotiation framework for personalized pricing of last minutes theatre tickets whose values are dependent on the time remaining to the performance and the locations of potential customers. In particular, case based reasoning and fuzzy cognitive map techniques are adopted in the negotiation framework to identify the best initial offer zone and adopt multi criteria decision in the scoring function to evaluate offers. The proposed framework is tested via a computer simulation in which personalized pricing policy shows higher market performance than other policies therefore the validity of the proposed negotiation framework.The Ministry of Education, Science and Technology (Korea

    KEMNAD: A Knowledge Engineering Methodology for Negotiating Agent Development

    Get PDF
    Automated negotiation is widely applied in various domains. However, the development of such systems is a complex knowledge and software engineering task. So, a methodology there will be helpful. Unfortunately, none of existing methodologies can offer sufficient, detailed support for such system development. To remove this limitation, this paper develops a new methodology made up of: (1) a generic framework (architectural pattern) for the main task, and (2) a library of modular and reusable design pattern (templates) of subtasks. Thus, it is much easier to build a negotiating agent by assembling these standardised components rather than reinventing the wheel each time. Moreover, since these patterns are identified from a wide variety of existing negotiating agents(especially high impact ones), they can also improve the quality of the final systems developed. In addition, our methodology reveals what types of domain knowledge need to be input into the negotiating agents. This in turn provides a basis for developing techniques to acquire the domain knowledge from human users. This is important because negotiation agents act faithfully on the behalf of their human users and thus the relevant domain knowledge must be acquired from the human users. Finally, our methodology is validated with one high impact system

    Pre-empting protectionism in services - the WTO and outsourcing

    Get PDF
    Cross-border trade in services is growing rapidly, with both industrial and developing countries among the most dynamic exporters. Despite the substantial global benefits from such trade, the adjustment pressures created in importing countries could provoke a protectionist backlash-some signs of which are already visible in procurement and regulatory restrictions. The current negotiations under the Doha Development Agenda offer an opportunity to lock in current openness and preempt protectionism. This paper describes how a bold initiative under the General Agreement on Trade in Services can help secure openness.Decentralization,Enterprise Development&Reform,Payment Systems&Infrastructure,ICT Policy and Strategies,Banks&Banking Reform,ICT Policy and Strategies,Banks&Banking Reform,Governance Indicators,Health Economics&Finance,Knowledge Economy

    This paper provides a short overview on the trade facilitation provisions in the RTAs in the Asia-Pacific region with a view to identifying the characteristics of trade facilitation provisions in existing RTAs and finding out good practices in this area. With the evolution of the definition of trade facilitation, a broader range of trade facilitation provisions are integrated into RTAs, which cover nine major areas. 1. Customs procedures and cooperation; 2. technical regulations, standards and SPS measures; 3. NTB especially administrative fees and charges; 4. transparency of laws, regulations and administrative rulings; 5. use of information and communication technology and E-Commerce; 6. mobility of business people; 7. freedom of transit; 8. facilitation in transport and logistics; 9. facilitation in payment and trade finance. The data about RTAs mainly come from the Asia-Pacific Trade and Investment Agreements Database (APTIAD).trade facilitation, RTAs, NTB, SPS measures, customs procedures and cooperation, technical regulations, standards, transport and logistics, trade finance, e-commerce, transparency.
