Content related to "user-profiling"

(1) Personal content recommender based on a hierarchical user model for the selection of TV programmes

In this paper we present our approach to user modeling for a personalized selection of multimedia content tested on a corpus of TV programmes. The idea of this approach is to classify content (TV programmes) based on the calculation of similarities between the description of content and the user model for each descrip- tion attribute. Calculated similarities are then combined into a classi¯cation decision using the Support Vector Machines. The basis for the calculation of similarities is a hierarchical structure of the user model, overlaid upon a taxonomy of TV pro- gramme genres. Preliminary results show that it works well with a varying quality of content descriptions including incomplete genre classi¯cation and arbitrary number of description attributes. The evaluation of the system performance was based on content described using the TV-Anytime standard, but the approach can be adapted for search of other types of content with multi-attribute descriptions.

(1) D9.6 Report on requirement monitoring

As the final document of WP9 this report lists various revised issues that have been described in separate deliverables in former times. Chapter 3 depicts the relevant actors and roles within the LIVE system. The final usage scenarios that could be observed during the preparation, production and post-processing of the Olympic Trial are described in chapter 4. They were the precondition for the revision of the final requirements presented in chapter 5. The description of the final requirements is oriented towards the presentation of the revised requirements in [LIVE D9.4] and follows the same outline. They again served as a foundation for the revision of the final system architecture of the LIVE production support system. Chapter 6 picks up the already defined workflows from [LIVE D9.5] and adapts and amends them according to the final requirements from chapter 5. This is accomplished by providing a componentbased view on the one hand and more detailed inspections on components which have been subject to major changes on the other. The first part intends to give an overview on the performed adaptations of the architecture for each component. The latter part is meant to serve as a guideline for the developers of the various components and tools on which interfaces will be needed between which components and which data has to be exchanged.

(1) D8.6 Report on the integration of the second system prototype

This document reports on the process of integration, testing and operation of the second prototype version of the LIVE System. It presents the complexity of the system including the implemented internal and external interfaces. In order to verify the development of the required and agreed function set and to ensure a certain level of stability, scalability and performance, extensive system testing was performed. The chosen approach, its realisation and conclusion comprise a major part of the report. In contrast to the first system prototype this version was foreseen to come to operation during the Summer Olympics 2008. A production team at the ORF in Vienna should be supported in their task to produce a multichannel interactive live programme. The operation of the system during the Olympic field trial is summarised from an integration point of view.
