    There are significant shifts, both at business and technology levels, toward services. Companies are deconstructing their functions and requirements in terms of explicit services, and then managing their value nets accordingly. Service-oriented architectures, supported by Web service standards and technologies, are rapidly becoming a standard approach for enterprise IT systems. The many functions ... View full abstract»

    As "traditional" Web service technologies are making their way into the mainstream distributed computing, service oriented architectures (SOA) gain more and more momentum in current and future IT infrastructures. In this talk, we give a motivation for doing such a transition from a market area point of view and present SAP's answer on the raising demand: The SAP enterprise services architecture (E...

  • Recommenders for commerce, content, and community

    Publication Year: 2005
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (32 KB) | HTML iconHTML

    Recommender systems are ubiquitous on the Internet for helping sell products - everything from automobiles to zebras (stuffed, anyway). Novel applications are emerging that use recommenders for non-Internet applications and that apply them to the problems of distributing content on the Internet and to developing online communities. Community-building is proving one of the most successful ways to c... View full abstract»

  • The power of business processes in e-commerce

    Publication Year: 2005
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (28 KB) | HTML iconHTML

    New trends are characterizing the e-commerce environment: the market is consolidating and good business concepts no longer suffice for sustainable success. Instead, maxims of the old economy like cost-efficiency, turn-over, and profit maximisation using known assets like business process management, innovation, and collaborations are being focused. E-commerce requires a good management of business... View full abstract»

  • Design of progressive auctions for procurement based on Lagrangian relaxation

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (192 KB) | HTML iconHTML

    Auction mechanisms have been found successful in implementing e-procurement, with the buyer as the auctioneer and the sellers as the bidders. Single round auctions are prevalently used in e-procurement, in which the suppliers submit sealed bids in response to the buyer's request-for-quote. The bid evaluation problem faced by the buyer is an optimization problem that selects the winning bids to min... View full abstract»

  • An auction mechanism for polynomial-time execution with combinatorial constraints

    Publication Year: 2005, Page(s):17 - 24
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (792 KB) | HTML iconHTML

    In this paper, we focus on the fact that even if we ignore the computational hardness of winner determination, a combinatorial auction is in many situations unlikely to produce the most efficient allocation. This is because each bidder has an exponential number of combinations to bid on, and basically only her own valuations as help when selecting combinations. This paper is based on the conjectur...

  • A framework for computing the outcome of proxied combinatorial auctions

    Publication Year: 2005, Page(s):25 - 32
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (544 KB) | HTML iconHTML

    Proxy bidding has been proposed for combinatorial auctions as a means to speed up the auctions, to simplify the user interface, and to limit strategic behavior. The only previously known solution method for proxy bidding in combinatorial auctions requires the auctioneer to run the auction with myopic bidders to determine the outcome. In this paper we present a radically different approach that com... View full abstract»

  • An adaptive bilateral negotiation model for e-commerce settings

    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (144 KB) | HTML iconHTML

    This paper studies adaptive bilateral negotiation between software agents in e-commerce environments. Specifically, we assume that the agents are self-interested, the environment is dynamic, and both agents have deadlines. Such dynamism means that the agents' negotiation parameters (such as deadlines and reservation prices) are functions of both the state of the encounter and the environment. Give...

    We describe the design and implementation of online bilateral negotiations. The negotiation middleware can be used in a stand-alone mode for electronic commerce and to provide support for other multilateral trading systems such as auctions and RFQ's, where it is integrated with bidding and bargaining processes. The negotiation engine design uses the state-machine formalism. It supports multi-attri... View full abstract»

  • A flexible model for tree-structured multi-commodity markets

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (696 KB) | HTML iconHTML

    In this paper we study tree-structured multicommodity, multi-unit markets. The concept is a way to handle dependencies between commodities on the market in a tractable way. The winner determination problem of a general combinatorial market is well known to be NP-hard. It has been shown that on single-unit single-sided combinatorial auctions with tree-structured bundles the problem can be computed ... View full abstract»

  • Truthful online auctions for pricing peer-to-peer services

    Publication Year: 2005, Page(s):59 - 66
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (168 KB) | HTML iconHTML

    We consider truthful online auctions that aim at optimizing sellers' revenues, representing service contributors' satisfactions, as a general model for pricing peer-to-peer services under the assumption of individual service consumer's rationality. For services that are in unlimited supply, we design a randomized truthful online auction with guaranteed revenue based on a randomized truthful offlin... View full abstract»

  • An auction for scheduling delivery of highly demanded products

    Publication Year: 2005, Page(s):67 - 74
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (168 KB) | HTML iconHTML

    We present a simple auction protocol for the sale of over-demanded goods with a delivery schedule. Under some reasonable assumptions, our mechanism is incentive compatible, collects only partial information about bidder's valuations, and empirical evidence suggests it converges to the efficient allocation.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (264 KB) | HTML iconHTML

    Many e-services are time-sensitive as the users request them for a specific time period. Such services need to be repeatedly offered to keep them constantly utilized. This paper studies winner selection strategies in a recurring auction for such time-sensitive e-services. We observe that because of uneven wealth distribution, the least wealthy bidders tend to drop out of recurring auction as they ... View full abstract»

    In recent years, clickstream-based collaborative filtering (CCF) recommendation models have received much attention mainly due to their scalability. The common CCF recommendation models are Markov models, sequential association rules, association rules, and clustering. The models have shown the trade-off relationship between precision and recall in performance. To address the trade-off relationshi... View full abstract»

    Recommender systems are a powerful tool for promoting sales in electronic commerce. An effective shopping recommender system can help boost the retailer's sales by reminding customers to purchase additional products originally not on their shopping lists. Existing recommender systems are designed to identify the top selling items, also called hot sellers, based on the store's sales data and custom... View full abstract»
