While there are several specific protocols currently being discussed to address the coordination of Web services-enabled business transactions, we consider the tentative hold protocol (THP) that allows the placement of tentative holds on business resources prior to actual transactions in order to provide increased flexibility in coordination. We present a framework for applying THP in conjunction with 2PC to the problem in which service providers independently manage resources and clients seek to acquire the resources from multiple providers as a single atomic transaction. The proposed framework also facilitates the performance optimization of THP through effective parameterization with the notion of overhold size and hold duration. Accordingly, a detailed analysis is carried out to obtain an efficient method that can optimize the performance by adaptively determining the hold duration. The simulation results show that the proposed adaptive approach yields a significant improvement over other non-adaptive policies.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

One way to minimize threats in such an open community is to use community-based reputations to help evaluating the trustworthiness and predicting the future behavior of peers. We present PeerTrust - a coherent adaptive trust model for quantifying and comparing the trustworthiness of peers based on a transaction-based feedback system. There are two main features of our model. First, we introduce three basic trust parameters in computing trustworthiness of peers. In addition to feedback a peer receives through its transactions with other peers, we incorporate the total number of transactions a peer performs, and the credibility of the feedback sources into the model for evaluating the trustworthiness of peers. We argue that the trust models based solely on feedback from other peers in the community are inaccurate and ineffective. Second, we introduce two adaptive trust factors, the transaction context factor and the community context factor, to allow the basic trust metric to incorporate different contexts (situations) and to address common problems encountered in a variety of online e-commerce communities. We present a concrete method to validate the proposed trust model and report the set of simulation-based experiments, showing the feasibility and benefit of the PeerTrust model.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

Although much research focus has been placed on achieving the lowest possible cost for the goods/services purchased we concern ourselves here with the operational procurement costs of the organization. The AutONA (automated one-to-one negotiation agent) system was conceived as a means of reducing these operational procurement costs enabling procurement departments to automate as much price negotiation as possible thus creating the option of reducing direct costs and/or redeployment of operational effort into strategic procurement requiring high human involvement. The problem domain has been limited to the automation of multiple 1:1 negotiations over price for quantities of a substitutable good subject to the organizations procurement constraints of target quantity, price ceiling and deadline. We present the design of the core reasoning system and preliminary results obtained from a number of experiments conducted in HP's Experimental Economics Lab. Our main conclusion is that AutONA could reasonably be deployed for automated negotiation having shown no evidence for being identified as an automated system by suppliers.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.
