Abstract

The TV sector is facing many drastic changes and is witnessing a rapid transformation. New technologies such as interactive TV, High Definition TV, very high capacity Personal Video Recorder (HD-DVB, Blu-Ray mobile storage), Home Theatre Systems, Video On Demand, Personal TV, etc. are entering the market. Television is moving from analogue TV to digital TV, from multi-channel TV to personal TV, from fixed TV to TV any-time any-where, from "provider centric" to "viewer centric", from TV watching to TV blogging and community TV. In the near future we can expect the viewer taking a more active control of the TV content, taking part in virtual TV communities and exchanging experiences, becoming creative and more participative. We will also see the TV content industry adding new interactivity dimensions to their content productions, offering the viewers the possibility to personalise their viewing of a TV production. We will see the TV channels and media providers mutating from TV content global push business models to users TV content individual pull models. This technological and TV business evolution is already taking place and will accelerate strongly in the coming years.

Abstract

The tutorial will address the various aspects of web information systems (WISs) such as purpose, usage, content, functionality, context, presentation. Starting from the strategic characterisation of a WIS, i.e. the very general question what the WIS is about, we first explore the kind of content that is to be presented in the WIS, and the kind of functionality, with which this content can be accessed, customised to the needs of particular WIS users, and updated. We then explore the modelling of users (or actors) of the WIS, their goals, and the tasks that have to be performed to reach these goals, and general rules for the formation of the WIS presentation.
On a lower level of abstraction the co-design approach emphasises content and functionality modelling. This level takes a deeper look into the scenes of the storyboard and links them with the necessary database support. Each scene will be supported by a view on some underlying database that will result in the content to be presented. With respect to functionality operations are added to the views. These operations have to be understood as detailed specifications of the actions that appear in the storyboard. In a last step we introduce three more extensions to the views. The first one is hierarchies, which enable more coarse or more detailed presentation of information. The second extension addresses adaptivity to technical restrictions such as channel bandwidth or end-devices. The third extension deals with presentation options using knowledge about cognitive models and facts from art to bring strategic considerations on ambience into the conceptual model.

Abstract

The need to extract knowledge from web data warehousing just 'in-time' for decision making has increased significantly. An efficient system that can generate up-to-date analysis and decision making of the ever changing web-based information will play a very important role in the current global market and society. The new era of business intelligence and web databases brings in new research and development issues whereby the efficient integration of various web data is needed and timely analysis of data resources are vital. Web Data Warehousing is a growing area that addresses the need for an efficient web data summary to support decision making and ensure the quality of web data analysis.
It is a common knowledge that the majority of web information structure is now represented in an XML based representation. As a result, many domain standard bodies have also started to introduce the use of XML encoding for their data specification standard, such as BPEL (Business Process Execution Language) which is XML-based representation for business processes, HL7 (Health Language 7) which includes XML-based representation for health informatics data exchange, AIXM (Aeronautical Inter Exchange Model) in aeronautical data exchange, and so on. It is then crucial that a data warehouse be built with an underpinning technology that supports global information interactions and management and this is the reason for the emergence of XML representation for web data warehousing.
The hierarchical nature of XML within an XML data warehouse and the fact that it represents a document warehouse rather than the traditional table based relational warehouse, have raised the need for new methodologies in dealing with warehousing issues.
In this tutorial, we will cover specific issues in XML data warehousing, including:

  • XML data warehouse design and construction
  • Temporal XML data warehouse
  • Right time XML data warehouse
  • Security and Privacy in XML data warehouse
  • Domain specific applications in XML warehousing: Health Informatics and Aviation (Air Traffic) Systems
