Title: "Agents and E-commerce: Hype and Reality"
Abstract: Agents can be used in many ways in electronic commerce. In order to use them as mediators it is almost always necessary to create a context in which the trading of the agents takes place. nly when the procedures of the trading are well defined it is feasible to delegate the actual trading task to an agent. This context can be provided in the form of an institution. Institutions determine the way e-commerce transactions are conducted and the required infrastructures to implement them. They give a predefined structure for specifying the product and also facilitate the negotiation process (about the price of the product). The institutions should be flexible enough to provide different types of scenarios. Depending on the type of product and market situation a certain type of trading can be chosen. This means that gents should be able to select the proper (most efficient or profitable) trading procedure for the case in hand. If the chosen procedure allows some freedom within the interaction (e.g. negotiating in different ways) the agent should agree with the other party on a common acceptable way of interacting. One cannot expect all agents to have the same capabilities, therefore agents should be designed in such a way that they can deal with both simple and complex agents in the context of the same institution. A new challenge will be to design trading agents that function as intermediaries for the trading procedure. They have specialized knowledge on strategies and trading protocols, such that the agents of the trading parties only have to have product and market knowledge and can leave the burden of finding the suitable trading procedure to the trading agent. In this talk we want to discuss in a systematic way, which types of (electronic) commerce transactions can be distinguished and what is the role of agents for these types. Depending on the role of the agents they should meet certain requirements. Specifically we will look at the requirements on the ability of the agent to communicate with its environment. In the first part of the talk, we will take a look at some theory about markets and institutions. In the second part, we will look at the interactions of agents within these electronic markets and institutions. In the last part we will look at the future roles that agents can fulfil in electronic commerce transactions and which research questions are of interest in this context.

Title: "The Misguided Silver Bullet: What XML Will and Will NOT Do to Help Information Integration"
Abstract: The eXtensible Markup Language (XML) offers many important benefits and improvements over its predecessor, HTML. But, articles have appeared about XML with exaggerated claims of it being a "Rosetta Stone" with "miraculuous ways" to almost automatically provide information integration. These claims are actually being believed by some executives. It is almost surprising that no one has claimed that XML can cure cancer and provide world peace! In reality, XML must face many of the same challenges that plagued Electronic Data Interchange (EDI) and database integration efforts of the past. To a large extent, there are both managerial and technical challenges - much related to the difficulties of attaining universally accepted semantically-rich standards. In this presentation, these challenges will be discussed with specific emphasis on the issue of dealing with a real-world with multiple "contexts." Some promising research directions, overlapping with the "semantic web" effort, will be presented.

Title: "Implications of Convergence on Education"
Abstract: The predictions such as long before the year 2000, the entire antiquated structure of college degrees, majors and credit will be in shambles” have not come true as of now. These are in spite of all indications, and good reasoning by the best of minds. The radical developments of technology at times counter our deeply established beliefs and at time reinforce them. The expansion of connectivity, bandwidth and access, resulting in the intense interactions lead the processes of Computing, Communication and Content, into a convergence of some kind the description of which is yet to arrive. These are not just convergences of technologies, but along with the convergence, the pervasiveness brings in paradigm shifts. The paradigms that were once the considerations of academics, the philosophers and the thinkers, are with the pervasiveness of technology become the concerns of common people. Several problem solving examples show that the solution of a problem depends a great deal on the way the problem is posed and communicated, and on the efficiencies of these processes. A given education system puts in pressures to learn as well as, pressures to unlearn ways of representation and thus problem solving. These pressures, while existed all the same, would have different manifestations with the increased efficiency of knowledge generation and access. An education system is a social process and is founded on a social infrastructure, the fabric of which is profoundly affected by the way know the world and share that knowledge. Thus is a cyclic process. In this discussion we look at the issues from the first principles, and attempt to identify the basic novelties of our times in the history of technology, make comparisons with earlier technological waves to see if there are lessons to be learnt and outline possible scenario.

Title: "Applications of ORA-SS: An Object-Relationship-Attribute Data Model for Semistructured Data"
Abstract: Semistructured data is becoming increasingly important with the introduction of XML and related languages and technologies. The recent shift from DTDs (document type definitions), a schema definition language, to XML-Schema, a more expressive schema definition language, for XML data highlights the importance of a schema definition for semistructured data applications. At the same time, there is a move to extend semistructured data models to express richer semantics. In this talk we highlight the most important concepts in ORA-SS (Object-Relationship-Attribute model for Semistructured data), a semantically rich data model for semistructured data, and through examples demonstrate the importance of ORA-SS. ORA-SS not only reflects the nested structure of semistructured data, but it also distinguishes between object classes, relationship sets, and attributes. It is possible to specify the participation constraints of object classes in relationship sets, and distinguish between attributes of relationship sets and attributes of object classes. Such information is lacking in existing semistructured data models, and is essential information for many purposes, such as designing efficient and non-redundant storage organization for semistructured data, defining meaningful semistructured views, view updatability and maintenance.

Title: "Building an Web-based Open Source Tool to Enhance Project Management, Monitoring and Collaboration in Scientific Projects"
Abstract: Scientific Cooperation, especially when co-workers and teams are dislocated, requires support for project management to distribute information to all members of the team. Such a support should allow project monitoring for team leaders and the management of resources, communication and documentation. In early 2000 the Austrian Federal Ministry of Education, Research and Culture launched a project for the management and support work of bilateral scientific projects between Austria and partner countries. This paper will describe the architecture and results of this project. The Institute for Software Technology develops an open source web application to enhance these cooperative tasks. The "Scientific Workplace"-tool allows management of users and skills, projects, tasks, to-do lists, resources (e.g. documents) and access control, project monitoring and messaging. The software will be distributed as open source application and is built itself upon open source server tools (application server, database, web-server) and uses open communication protocols (SOAP) and XML file-formats. The server application as well as the administration application and the user front-end are implemented in a platform independent way. This increases the flexibility of use as well as the spread of the application as there are no hurdles in terms of license fees or option to make modifications/adaptations.

Title: "Trusted Electronic Commerce Transactions"
Abstract: the dramatic changes in telecommunications and computing technology as evidenced in the Internet and World Wide Web have sparked a revolution in electronic commerce (e-commerce) and e-commerce applications. But in spite of the well-publicised success stories, many businesses and consumers are still cautious about participating in e-commerce, and security concerns are often cited as being the single most important barrier. In this talk we focus on two main issues that might help in building trusted e-commerce transactions: 1. COPS, a technical infrastructure for building adaptable electronic markets with main focus on security and fairness, and 2. MOSS, a business process reengineering methodology for analysing and modelling the security semantics of electronic commerce transactions. Both, COPS and MOSS are helpful to control the risks involved in dealing (trading) with untrusted parties in an open electronic commerce environment.

Title: "XML Benchmarks Put to the Test"
Abstract: The effectiveness of existing XML query languages has been studied by many who focused on the comparison of linguistic features, implicitly reflecting the fact that most XML tools exist only on paper. In this paper, with a focus on efficiency and concreteness, we propose a pragmatic first step toward the systematic benchmarking of XML query processing platforms. We begin by identifying the necessary functionalities an XML data management system should support. We review existing approaches for managing XML data and the query processing capabilities of these approaches. We then compare three XML query benchmarks XMach­1, XMark and XOO7 and discuss the applicability, strengths and limitations of these benchmarks. We highlight the bias of these benchmarks towards the data centric view of XML and motivate our selection of XOO7 to extend with document centric queries. We complete XOO7 to capture the information retrieval capabilities of XML management systems. Finally we summarize our contributions and discuss future directions.

Title: "Logic Programming Languages for the Internet"
Abstract: We specify the major characteristics of the Internet under the headings: heterogeneity, service characteristics, dynamic nature, no global notions, and unreliability (i.e. security and partial failure). In the process, we identify five categories of Internet services: hosts, active entities, agents, semistructured data, and passive code. Logic Programming (LP) languages for the Internet are divided into six broad groups: shared variables, coordination, message passing, client-side execution, server-side execution, and integration of heterogeneous data sources. Within each group we attempt to highlight the advantages and disadvantages for Internet programming in terms of our Internet characteristics and services, and describe LP languages that typify the group.

Title: "Towards Integrating XML and Relational Database Systems"
Abstract: Relational databases get more and more employed in order to store the content of a web site. At the same time, XML is fast emerging as the dominant standard at the hypertext level of web site management describing pages and links between them. Thus, the integration of XML with relational database systems to enable the storage, retrieval, and update of XML documents is of major importance. Data model heterogeneity, however, and schema heterogeneity makes this a challenging task. This tutorial focusses on several heterogeneity aspects relevant for such an integration and discusses different approaches for integrating XML and relational database systems.

Title: "Data Warehousing"
Abstract: Information is one of the most valuable assets of an organization and when used properly can assist in intelligent decision making that can significantly improve the functioning of an organization. Data Warehousing is a recent information technology that allows information to be easily and efficiently accessed for decision making activities. The On-Line Analytical Processing (OLAP) tools are well-suited for complex data analysis, such as multidimensional data analysis, and decision support activities which access data from a separate repository, called a data warehouse, that selects data from many operational, legacy, and possibly heterogeneous data sources. In this part of tutorial, we review the current state of the art in the data warehousing technology. In particular, we start with the architecture of a data warehouse system, and then discuss the main steps in designing and maintaining a data warehouse. We further discuss the multidimensional model, multidimensional query languages, indexing, and implementation schemes. We also discuss the OLAP architecture, query operations and metadata repository. A number of technical issues for exploratory research are also discussed.
