In particular, we pay attention to the performance issues on ITWS data transmission and compression. Since SOAP message is a textual document, we can improve the data transmission time by compressing data on transmission. In our experiment, compressing data before or after SOAP serialization both can reduce the size of transmitted message down to as little as 2% and cut the response time to a quarter of the original message.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

The aim is to create modularized services supporting the business processes within their organization and also those external entities participating in these same business processes. Current Web service frameworks do not include the functionality required for Web service execution performance measurement from an organization perspective. As such, a shift to this paradigm is at the expense of the organization's performance knowledge, as this knowledge will become buried within the internal processing of the Web service platform. This research introduces an approach to reclaim and improve this knowledge for the organization establishing a framework that enables the definition of Web services from a performance measurement perspective, together with the logging and analysis of the enactment of Web services. This framework utilizes Web service concepts, DSS principles, and agent technologies, to enable feedback on the organization's performance measures through the analysis of the Web services. A key benefit of this work is that the data is stored once but provides information both to the customer and the supplier of a Web service, removing the need for development of internal Web service performance monitoring.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

As representative models, we consider a single seller market and a two seller market, and formulate the dynamic pricing problem in a setting that easily generalizes to markets with more than two sellers. We first formulate the single seller dynamic pricing problem in the RL framework and solve the problem using the Q-learning algorithm through simulation. Next we model the two seller dynamic pricing problem as a Markovian game and formulate the problem in the RL framework. We solve this problem using actor-critic algorithms through simulation. We believe our approach to solving these problems is a promising way of setting dynamic prices in multi-agent environments. We illustrate the methodology with two illustrative examples of typical retail markets.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

This problem has been recognized as central to enhance the contribution of the computer science community to the field. We put forward the notions of structure and budget as main guidelines towards the generation of succinct and realistic input data. We describe a computational framework for the analysis of existing algorithms against realistic benchmarks, and use it in the context of two real world scenarios, i.e., real estate and railroad track auctions. The results of this analysis suggest that the obstacles to using (one round) combinatorial auctions in real world applications might be of an economic nature rather than a computational one.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

An application area of high interest is day-ahead power markets. If these are to be opened for consumer side bidders and local production bidders, the number of actors on the market grows dramatically, and new market mechanisms and algorithms are needed. Another interesting application area with many similarities is bandwidth markets. The design of large flexible markets with time dependent goods is a computational challenge. We present a computationally tractable mechanism for time dependent markets. By a number of predefined bid types, it offers useful flexibility to the bidders. We present the market mechanism and the corresponding matching algorithm together with some analysis of its behavior.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.

Depending on the negotiation mechanism such search space can be dynamic wherein agents may be cooperative or non-cooperative. In a realistic negotiation, agents are unwilling to reveal their utility functions to their opponents or collaborators. These important characteristics of negotiation increase the complexity of the design of efficient and effective negotiation agents. We propose an approach that combines a co-evolutionary mechanism with the notion of degree of satisfaction. The former effectively searches the space, while the latter improves negotiation efficiency. Agents under the proposed scheme can carry out cooperative, or non-cooperative, without revealing their utility functions. The proposed approach is implemented as a prototype system and evaluated through a number of experiments. The evaluation shows the effectiveness of the proposed approach in cooperation and non-cooperation.","PeriodicalId":375124,"journal":{"name":"EEE International Conference on E-Commerce, 2003.
