    Auctions have been a popular trading paradigm for centuries but have gained new interest through world-wide trading on the Internet. Many B2C sites are embracing reverse auctions as an additional service to registered customers. In all these cases the efficient notification of the participants is essential. We develop the notion of a meta-auction that allows a potential buyer to roam automatically... View full abstract»

    Negotiation between buyer and supplier parties is an important part of commerce activities. Complex conditions are exchanged during a negotiation. It is important to realize a database of such conditions and provide querying facilities in an advanced electronic marketplace. We introduce the notion of dynamic constraints to model such complex negotiation conditions, and propose a new query language... View full abstract»

    An ultimate goal for modern Internet services is the development of scalable, high-performance, highly-available and fault-tolerant systems. Replication is an important approach to achieve this goal. However replication introduces the issue of consistency among replicas, which is further complicated by network partitions. Generally, higher consistency levels result in lower system availability in ... View full abstract»

    This paper presents a new Web-based technique for visualizing dynamically large hierarchies, tree or category structures in 3D worlds. The technique uses CGI-scripting, SQL queries and applet-based production systems to visualize in an efficient and versatile manner general category structures that are stored in relational databases. First, appropriate SQL queries extract the hierarchical category... View full abstract»

    This paper describes two architectures for building pay-per-run software systems: the download-once approach and the dynamic-download approach. These are systems that allow the user to pay for each execution of an application, instead of buying a more expensive user license. This is a new model for software distribution in which developers charge small fees for each execution in order to increase ... View full abstract»

    Organization of a Web site is important to help users get the most out of the site. A good Web site should help visitors find the information they want easily. Visitors typically find information by searching for selected terms of interest or by following links from one Web page to another. The first approach is more useful if the visitor knows exactly what he is seeking, while the second approach... View full abstract»

    Efficient means of electronic interaction are an essential requirement for the integration of different companies' business processes along the value chain. Until recently, this interaction relied on expensive, complex and inflexible solutions, mostly based on EDI or some proprietary means. The high set-up costs and time associated with this type of infrastructure prohibits the dynamic forging of ... View full abstract»

    We propose domain name service (DNS) server extensions to support global replicated services. The DNS server collects routing metrics from routers for cached replicated servers. Upon receiving a DNS request from a host in its domain, the DNS automatically returns the IP address of a server available from an IP address pool that has the best routing metrics preferred by the host. Possible extension... View full abstract»

    Recently, in Japanese convenience stores, kiosk terminals have started providing customers with travel and ticket sales services with operators by phone. However, these systems have many problems: customers often make mistakes in operating kiosk systems and in calling experts, and children often play with the terminal and make unnecessary calls to experts. We propose an information kiosk system wh... View full abstract»
