CHORUS+ Project

Coordinated approacH to the EurOpean effoRt on aUdiovsual Search engines



25-26 September 2012: International Workshop on Search Computing (Brussels, Belgium)

Search has become an important and necessary component of many diverse ICT applications.  A large number of business and application areas depend on the efficiency and availability of search techniques that are capable to process and retrieve heterogeneous and dispersed data. Search techniques are directly related to a number of research topics and challenges ranging from multimodal analysis and indexing to affective computing and human aspects as well as to various socio-economic challenges including standardization, legal and social issues.
This workshop will be a platform for the discussion of the key research, business and socio-economic issues in search computing. It will consist of invited talks and panels from experts in the field, results from the CHORUS+ Network and the Media Search Cluster. The workshop will include keynote from Stefano Ceri, professor at the Dipartimento di Elettronica e Informazione (DEI), Politecnico di Milano and Masataka Goto, Leader of Media Interaction Group, National Institute of Advanced Industrial Science and Technology (AIST), Japan.

Starting date: January 2010
Duration: 36 months

Description and Objectives: CHORUS+ is a Coordination Action which objectives are to coordinate national and international projects and initiatives in the search-engine domain and to extend this Coordination to non-European countries. CHORUS+ is a continuation project of CHORUS. CHORUS+ aims at creating the conditions of mutual information exchange and cross fertilisation between the FP7 projects in the search-engines domain and the recently launched national and international initiatives in this area. A particular emphasis on setting concrete R&D and industrial objectives for multimedia search in Europe is planned through the implementation of discussion groups limited to selected representatives (industry and academia) and the organisation of and open participation in workshops, conferences and summer schools.


In CHORUS+ work will be done on the following key issues:

  • Support the integration and strengthening of a single European research area by stimulating interaction and co-ordination among research projects at the EU level in the area of audio-visual search engines.
  • Extend cooperation and coordination to Asian countries (Japan, Singapore and China) and to the USA, since the topic of multimedia search engine represents a global concern today which needs a wider cooperation scope than European frontiers. Emergent efforts from these countries will be watched and establishing connections will be investigated.
  • Support the creation of a multi-disciplinary approach for the implementation and setting-up of audio-visual search engines in the EU.
  • Support the dissemination of results and strategies developed within the ICT Programme.


Description of work

IPTS is the coordinator of the CHORUS+ work on the Socio-economic and Policy Analysis of the European search field, which aims to understand the current state of play in the European search landscape, to explore its future prospects, and to contribute to the effective strategies for the growth of the search market in Europe.

Such work will focus on the analysis of the mobile search and enterprise search segments, these two areas being considered particularly important for both European research and industry.

Research will be conducted according to a range of strategies including desk-research, information gathering throughout the AV-Search Consortia and forward-looking tools, like scenario building exercises or Delphi and aim to understand the larger picture of potential challenges and benefits in the area of multimedia search over the next 5 years or longer.

Briefings, background material on European policies or socio-economic issues as well as viable (and enforceable) policy options will be produced based on the assessment of current and future challenge and on the analysis of the current EU regulatory environment.

Techno-economic and socio-economic analysis of Mobile Search

The mobile base will reach nearly 5,000 million subscribers worldwide by 2012 (forecast as of early 2009). By the end of 2013, broadband mobile connections (3G, 3.5G+) will account for more than half of all connections and 40% of all subscribers will be using mobile internet. The widespread adoption of mobile communications will lead to an explosion of mobile content and applications, which in turn will require efficient and user-friendly ways to be accessed. Search functionalities are therefore expected to become the enabling platform for the growth of mobile services, thus becoming equally or even more critical in the mobile domain than they are in the wired environment. As a result, mobile search is becoming an attractive expansion market.

The current state of play (as of 2009) shows that search on mobiles is driven by different kinds of applications. The first ones are those adapting or emulating web search processes and services to the mobile environment. The second are leveraging on the specificity of handheld devices and their use in mobile environments. In particular they exploit that mobile devices can capture data about the user, and his/her surrounding, thus enabling context-aware and location-aware search services in current and future ambient intelligent environments (e.g. making use of wireless sensors and cognitive techniques).

The aim of this research is to gain insights of the techno-economic trends in mobile search and how it will impact the European Economy and Society, particularly with respect to the second set of applications.

The first activity designed to achieve the above objectives is the "Exploring the future of Mobile Search" expert workshop which was held in Ghent (Belgium) on the 9th of June 2010.

Techno-economic analysis of Enterprise Search Solutions

Europe has a number of active companies providing Enterprise Search solutions. Given the current market structure (as of 2009) of very few large players, some medium sized companies and many small but dynamic companies, Enterprise Search solutions providers are currently facing a critical phase in which mergers and acquisitions may arise before the sector reaches consolidation. One of the risks is that at the final consolidation stage, many of these companies may be acquired by non-European companies and their associated expertise may fade away.

In this respect, this work package aims at identifying and assessing the potential of future enterprise search solutions so as to make recommendations about how they will impact the European economy in terms of rate of innovation of industry, added value to the companies, increasing competitive advantage, etc.

For this undertaking the IPTS aims at describing the dominant techno-economic model of Enterprise Search solutions by providing evidence and supporting data with the long-term objective of identifying potential policy recommendations based upon an analysis of opportunities, challenges and threats for Europe.
