Audio/Visual and Non-traditional Objects

Stavros Christodoulakis describes the principal aims and activities for this cluster.

Introduction

Digital libraries will capture, organize, store and manage the access to large amounts of digital information regarding human knowledge, culture, and history in various, possibly interconnected, presentation forms like video, audio, images, etc. These types of non-traditional content will often be highly structured into segments and/or semantic units (objects) which will be indexed and interconnected with other objects in a variety of ways allowing flexible access, transcoding, browsing, semantic integration, presentation, and personalization according to the application functionality, the domain of knowledge described, the presentation device and the user's preferences and goals. The WP3 cluster entitled "Audio-visual and non-traditional objects" will focus on metadata capture for audio-visual content, universal access and interaction with audio-visual libraries, together with the management of audio-visual content in digital libraries.

Aims and Objectives

The overall objectives of this cluster are to establish a common ground of knowledge for European researchers about the state of the art, to identify the direction that research will take and realise important new applications for digital libraries with audio-visual and non-traditional objects. In particular, the cluster aims at:

  • Establishing common functionalities and advancing the state of the art in the area of metadata capture from audio-visual content, including the investigation of issues related to multimodal information extraction, and the use of domain-specific, context-specific and historical information in the extraction process.
  • Establishing common foundations and advancing the state of the art in the area of information access and interactions with audio-visual digital libraries exploring multimedia content standards, domain- and context-specific knowledge as well as investigating advanced interactions and interfaces to multimedia content.
  • Establishing common foundations and improving performance in the area of management of audio-visual content, including new database models and data structures for storage, retrieval, and dissemination of multimedia data in emerging architectures and applications.

Cluster Activities

For the first 18 months period of the project, the foreseen activities are organized in 6 distinct tasks:

  • Cluster Management including the setting up and maintenance of cluster website and the organization of cluster workshops for the dissemination of cluster results and the discussion and development on new proposals, solutions and achievements for audio-visual digital libraries. (Task leaders: Technical University of Crete, Università di Firenze)
  • Establishment of a Forum on Audio-Visual Digital Libraries to enable international networking, communication between the cluster participants, bilateral collaboration and prototype evaluation as well as the organization of overviews and surveys of developments and activities in the area of audio-visual content. (Task leader: University of Amsterdam)
  • Assembly of Demonstrators and Testbeds to demonstrate innovative solutions and applications for audio-visual digital libraries, to create domain- and context-specific testbeds and to demonstrate multi-channel delivery scenarios for audio-visual content. (Task leaders: Technical University of Crete, Università di Firenze)
  • Common Foundation and Joint Research on Metadata Extraction to investigate the state of the art in the automatic extraction of audio-visual metadata and produce new models and experiments with prototype systems for automatic and semi-automatic extraction models in domain-specific and context-specific audio-visual application environments. (Task leader: Università di Firenze)
  • Common Foundation and Joint Research on Information Access and Interaction to investigate the state of the art in audio-visual information access and interaction. In particular, it will explore models based on the integration of existing frameworks of multimedia content (e.g. MPEG-7, TV_Anytime) and domain-specific extensions of those models to enhance the effectiveness of retrieval and provide value-added services. It will also explore models of user interaction based on the concept of context and context-based retrieval in audio-visual digital library applications. Moreover, this task will study models and interfaces for advanced applications of audio-visual digital libraries, develop new solutions and make experiments with prototype systems for processing, semantic transcoding, interaction and presentation of audio-visual content for different delivery media and interaction devices so as to adapt the users' preferences about content to the specific characteristics of the delivery media and the users' terminals. (Task leader: Technical University of Crete)
  • Common Foundation and Joint Research on Management of Audio-visual Content to study the management aspects of audio-visual data. In particular this task will investigate the state-of-the-art database models and data structures for the storage, retrieval and dissemination of audio-visual metadata and will conduct experiments with prototype systems. It will also investigate the state-of-the-art models for profiling and stereotyping the users of the most important multimedia applications and current dissemination strategies. (Task leader: Consiglio Nazionale delle Ricerche)

Work in the cluster was launched by the kick-off meeting held in Paris at INRIA on 16 January 2004. During this meeting the work scheduled was specified in detail and the cluster steering committee was nominated. The cluster also nominated colleagues to be responsible for liaison with the other DELOS II clusters in order to facilitate integration within the network. We also decided that the first cluster workshop would be held in Chania, Crete during September 2004.

The A/V-NTO Cluster website http://delos.music.tuc.gr/

and the Cluster mailing list

have been established to facilitate communication between the partners and the dissemination of cluster results.

The complete list of A/V-NTO partners is also available.

The cluster is currently working on the preparation of three state of the art reports on metadata extraction, information access and interaction as well as on management of audio-visual content.
