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 is useful when the visitor has less of a preconceived notion about what he wants. The organization of a Web site is especially important in the latter case. Traditionally, Web site organization is done by hand. In this paper, we introduce the problem of automatic Web site construction and propose a solution for solving a major step of the problem based on decision tree algorithms. The solution is found to be useful in automatic construction of product catalogs.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

However, the difficulties during the exchange communication are the inconsistency in the represented value and how to make the data interchange meaningful. This paper presents the use of semantic value as the unit of exchange and a context-agent to facilitate the exchange during e-negotiation. An XML framework is used to declare the values of the properties of the semantic values. Rule-based representation is also provided to give context information for the semantic value. An ontology server specifies the concepts or terminology mapping. The explicit representation of semantic value reduces errors and frees applications from being concerned with conversions. It also makes it possible to understand the impact of semantic changes to the data among different heterogeneous information systems.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

SMIL is a simple and standard way to specify a timeline-based synchronized multimedia presentation over the Internet. It is a declarative authoring language based on the Extensible Markup Language (XML) to define language-specific data types and tags. Since it is based on XML, it can be included in XML-based catalogs and data interchange in order to provide multimedia presentations. Instead of using proprietary multimedia document types, SMIL elements are standard way to include them. We discuss different ways to include multimedia presentations in a Web-based catalog. We also describe a component-based SMIL player written in Java. Different components can be put together to create a multimedia player that can run on the major Web browsers as a Java applet.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information 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 the presence of network partitions. Thus, there is a fundamental tradeoff between consistency and availability in building replicated Internet services. We argue that Internet services can benefit from dynamically choosing availability/consistency tradeoffs. With three consistency metrics, Unseen Writes, Uncommitted Writes and Staleness, we show how consistency can be meaningfully quantified for many Internet services. We present the design of the TACT (Tunable Availability and Consistency Tradeoffs) toolkit that allows Internet services to flexibly and dynamically choose their own availability/consistency, tradeoffs, enabling differentiated availability/consistency quality of service. Further TACT makes it possible for Internet services to dynamically trade consistency for performance.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

Although XML documents can be accompanied by a document type definition (DTD) that defines the structure of the documents, the presence of a DTD is not mandatory. The difficulty in deriving the DTD for XML documents lies in the fact that DTDs are of a different syntax from XML and that prior knowledge of the structure of the documents is required. In this paper, we introduce DTD-Miner, an automatic structure mining tool for XML documents. Using a Web-based interface, the user is able to submit a set of similarly structured XML documents and the system automatically suggests a DTD. The user is also able to further refine the DTD generated to reduce the complexity by relaxing some the rules used in the system.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

Using analytical and simulation models, we show the potential performance gains obtained by e-commerce sites that distribute their services among e-representatives and contribute to reduce bandwidth consumption and network latency.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

Virtual market systems, however need elaborate schemes for keeping certain property values dynamically updated. Dynamic property updates can be supported by using the dynamic property concept of the CORBA trading service. Specifying, executing and managing the algorithms used to compute the values of the dynamic properties, however, is outside the scope of the related CORBA standard. This paper presents the concept and the implementation of a generic engine which can be used to create, edit, manage and execute dynamic property evaluation algorithms. This approach brings about a number of benefits: an improved development environment, a simulation test-bed, improved management and maintenance capability, and a structured way of linking the trading service to legacy systems. The resulting system has been used extensively as part of the ViMP (Virtual MarketPlace) set of development tools to create a number of dynamic virtual markets.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

In CapBasED, an activity consists of interdependent tasks (atomic activities) that are executed by an agent.

In this paper, we propose a multi-agent system model, introduce a measurement of speed-up/slow-down, and develop different scheduling policies that allow for faster executions based on user's requests. Our scheduling framework is developed under the assumption that there are no additional resources for speeding-up the activities and it is based on re-scheduling activities in agent's queues.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.
