These protocols ensure the confidentiality and integrity of information exchanged. In addition, researchers have identified other desirable properties, such as money atomicity, goods atomicity and validated receipt, that must be satisfied by e-commerce protocols. This paper shows how model checking can be used to obtain an assurance about the existence of these properties in an e-commerce protocol. It is essential that these desirable properties be satisfied even in the presence of site or communication failures. Using the model checker, we evaluate which failures cause the violation of one or more of the properties. The results of the analysis are then used to propose a mechanism that handles the failures to make the protocol failure-resilient.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

We present several heuristic algorithms that attempt to maximize the revenue earned by an e-commerce merchant providing such a service.

From the points of view of Internet advertisers, it will be very advantageous if Internet advertising can be automatically carried out. Software agent technology offers a new paradigm for advertising on the Internet. It can be used to automate several of the most time consuming stages of Internet advertising. This paper surveys the application trends of software agents in Internet advertising and proposes some solutions to these trends at the same time.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

The powerful architecture of the Internet makes conducting business possible. In e-commerce applications the number of goods and the exchange of information are increasing. In order to make full use of the Internet's potential, user-friendly access to information is needed for the optimal distribution of information and knowledge. User-friendliness means easy technical access and methods to enhance the user's comprehension of the information. This can be achieved with the support of information visualization. Therefore, we have developed the WWWW model, which demonstrates how e-commerce can benefit from visualization. The PROSECO system is designed as an open scalable framework architecture to easily provide and access any services needed for distributed visualization of abstract data. We demonstrate the capabilities of our concepts by providing user-friendly access to economic information.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

However, to realize this potential it is necessary to be able to extract structured data from XML documents and store it in a database, as well as to generate XML documents from data extracted from a database. Although many DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS- and platform-independent load/extract utility as well. In this paper, we describe such a utility that solves the following problems: (1) loading data from XML documents into relational tables with a known schema, (2) creating XML documents according to a known document type definition (DTD) from data extracted from a database, (3) generating relational schemas from XML DTDs for on-the-fly storage of XML documents, and (4) generating XML DTDs from relational schemas for on-the-fly extraction of relational data. We introduce a language to describe a mapping between an existing XML DTD and an existing relational schema and discuss some of the interesting issues arising from such a mapping.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

Some seasonal commodities and future contracts have to deal with uncontrollable factors such as the elasticity of the price and the constant variation of the demand. These trends present some new challenges in bid evaluations and business decisions. We have developed a system, which uses a hierarchical decision-criteria framework to handle complex constraint hierarchy with n-ary variables. In addition, the system provides the mechanism to analyze and forecast certain events based on the seasonal and historical data.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

However, developing efficient maintenance techniques for materialized views over dynamic Web data sources is more challenging than in the traditional database context. In this paper, given a Web view specified in XQL, we propose an aggregation path index structure to hold a collection of \"qualified\" objects with respect to the query pattern. By utilizing the pre-computed auxiliary information stored in such an index, our algorithms show that Web view maintenance can be done more efficiently. Cost analysis and experimental studies on the advantages of our incremental maintenance approach compared to state-of-art solutions illustrate the performance gains of APIX.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.

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 across auction sites and we identify critical communication and notification requirements of the next generation of Internet-scale trading systems. First, today's information systems are limited in their growth and interaction potential because the typical client-server and n-tier system architectures are solely based on a request/response interaction; second, the user-initiated query metaphor from the database domain is the primary means for information acquisition; and third, many assumptions about the meaning of data and notifications provided and exchanged through the Internet are left implicit. We argue that Internet-scale business applications require publish/subscribe as an additional interaction paradigm, should leverage proactive information dissemination and caching mechanisms, and that there is a compelling need for metadata-based infrastructures providing common vocabularies for semantically meaningful exchange of data and notifications. We illustrate these points through examples from the auction domain and the development of the meta-auction concept.","PeriodicalId":340737,"journal":{"name":"Proceedings Second International Workshop on Advanced Issues of E-Commerce and Web-Based Information Systems.
