REVEAL THIS
Retrieval of Video and Language for The Home user in an Information Society
REVEAL THIS developed content programming technology able to capture, semantically index, categorise and cross-link multimedia and multilingual digital content coming from different sources, such as television, radio and the web. Users of the system could satisfy their information needs through personalized semantic search and retrieval, summaries of content and translation of them into their desired language.
Impact
REVEAL THIS addresses a basic need underlying content organisation, filtering, consumption and enjoyment by developing systems that will help European citizens and content providers keep up with the explosion of digital content scattered over different platforms, like radio, TV, World Wide Web, different media, such as speech, text, image and video, as well as different languages. The project's application domains currently include EU politics and travel information.
REVEAL THIS main innovation
The development of methods and tools for content-based organization and filtering of the large amount of multimedia information that reaches the user through many and different channels is a key issue for its effective consumption and enjoyment. In fact, despite recent technological progress in the new media and the Internet, the key issue remains 'how digital technology will add value to present information channels and systems'.
REVEAL THIS aims at answering this question by tackling the following scientific and technological challenges:
- enrichment of multilingual multimedia content with semantic information like topic of a multimedia document, speakers, actors, facts and events mentioned, as well as keyframes relevant to user profiles
- semantically linking multimedia information presented in different media and languages
- development of cross-media categorization and summarization engines
- deployment of cross-language information retrieval and machine translation technologies in order to allow the user search for and retrieve information according to his language preferences
REVEAL THIS results so far
In the initial phase, REVEAL THIS established precise user requirements, modes and scenaria of system use, and it conducted a survey of the relevant market sector and associated technological solutions. Based on these and development considerations, EU politics and travel have been chosen as the project's main applicative domains.
During the second year, REVEAL THIS has completed the development and integration of all subsystems, the Cross-media Content Analysis & Indexing Subsystem, Cross-media Categorisation, Cross-media Summarisation, Cross-lingual Translation Subsystem, and the Cross-media Content Access and Retrieval Subsystem.
The final prototype consists of two major components: The Multimedia Indexer and the Media Server. The Multimedia Indexer integrates the medium-specific subsystems, like the speech, video, image and text processors, and higher-level subsystems, like the cross-media categoriser, cross-media indexer, textual and visual summariser and cross-lingual translator. The Media Server stores uploaded XML metadata together with the original media, multimedia summaries and selected keyframe images, and makes its content accessible to users in various forms. It supports searching for content or filtering content based on the metadata. It provides multi-lingual search, multi-media presentation of retrieved content, personalisation, summarisation, and delivery to different devices.
The information the user can access consists of European politics issues, sourced from European Parliament related data, associated national news tv & radio programmes, web text data, and travel information, sourced from travel documentaries, national tv programmes and web texts. Information is sourced in English and Greek. Two information access scenarios have been implemented: a pull scenario by which a user retrieves multimedia information through a web based user interface, and a push scenario by which a user receives information filtered by the preferences he has declared to the system. User acceptance tests are currently under way and will continue in the last stage of the project.
