Semantic Web - EU perspectives

W3C Semantic Web Tour

Investing in ict research and development l.jpg
Investing in ICT research and development

“The computer age is everywhere except in the productivity statistics” (Solow, 1987)

  • Productivity growth in US since 1995 coincides with ICT growth. Not same growth rate in Europe:

    • the characteristics of European economy

    • the “dot.com” shake-outs

  • It is a long-term haul before ICT becomes a general utility comparable with energy or transport networks.


Longer term ict trends l.jpg
Longer-term ICT trends

“The world produces between one and two exabytes of unique information per year, which is roughly 250 megabytes for every man, woman, and child on earth”.(SIMS/ Berkeley, 2000)

  • ICT today

  • shrink-wrapped PC configs

  • Narrow bandwidth

  • Objects are just objects

  • Web “dumb, boring and isolated”

  • Applications “islands” eWork/eGov

  • Internet users “only” in millions

  • Tomorrow: Ambient Intelligence?

  • Self-aware devices, sensors, etc

  • Broadband, wireless multimedia

  • Billions of tagged objects

  • “adaptable, executable, X-Internet”

  • Seamless interoperability

  • Internet parallels mass media

Some market drivers l.jpg
Some market drivers

  • Technology:

    • broadband is taking off (incl. mobile)

    • more integration between digital devices - new forms of content processing

  • Markets

    • information value chain becoming less linear, more “just-in-time”, more distributed

    • increasing blur between content providers and users (e.g. P2P)

  • User pull

    • information overload now at individual level.

    • systems to be more user-centric / ambient.



Evolving from data and syntax to semantics l.jpg
Evolving from data and syntax to semantics

  • Semantic Web roadmap

  • Web services initiatives worldwide

  • advanced multimedia processing - e.g. scene analysis

  • knowledge lifecycle: creating knowledge bases, maintaining them, reasoning on them (in Web environment)

  • scaleable natural language processing / linguistic analysis to help in annotation

  • agents, multi-agent frameworks, etc

    Involves several scientific disciplines, developing new communities of interest.


Slide7 l.jpg

Main challenges

  • Help overcome information overload

    • better integrate content and services across different platforms

    • more advanced querying, searching etc

  • seek industrial / socio-economic benefits

    • help promising content technologies to mature: scaleable, robust, cost-effective etc

    • address issues like cost-benefits and usability

  • support ever-more complex work processes

    • be time-critical, collaborative, dynamic

    • add intelligence e.g. inferencing, reasoning


Slide8 l.jpg

eEurope 2005

  • Policy aims for 2005:

    • modern online public services

      • e-government, health, learning etc

    • a dynamic business environment

      enabled by

    • widespread availability of broadband access at competitive prices

    • a secure information infrastructure

      through e.g. :

    • policy measures (eg review legislation on e-business)

    • good practice, benchmarking.


Slide9 l.jpg

IST FP5 Semantic Web technologies (2001)

Objective:

Focus European RTD on Semantic Web, including on ontology best practice, semantic indexing and analysis, resource and services discovery, semantic-based interfaces / visualisation.

Today: over 30 projects involving over 250 research and industry organisations, including:

  • SWAD-Europe W3C-based outreach project

  • OntoWeb Thematic Network on ontologies with ca 130 members

  • pilot applications e.g. on hidden Web, web-based KM, scientific discovery, etc

  • “extensions” of SWT e.g. towards multimedia, P2P, GRID etc,


Fp6 semantic based knowledge systems 2002 l.jpg
FP6 - Semantic-based knowledge systems (2002)

Objective:

RTD should aim to :

  • develop semantic-based and context-aware systems which can acquire, organise, process, share and use the knowledgeembedded in multimedia content

  • maximise automation of the complete knowledge lifecycle

  • achieve semantic interoperability between Web resources and services.

    Also found in other IST areas such as cross-media content, networked businesses and governments, eLearning, digital culture, cognitive systems...

Guidelines support


Rtd approach l.jpg
RTD approach

  • Foundational research

    • mainly via Networks of Excellence

    • ontology methods, formal languages (eg OWL), models

  • Component research

    • mainly through STREPS

    • annotation, indexing, search engines, visualisation etc

    • performance, robustness, costs...

  • System-level research

    • integration of above, mainly via Integrated Projects

    • demonstrations and pilot applications

    • user / market acceptance / impact


Call 1 results preliminary l.jpg
Call 1 results - preliminary!

  • Over 120 proposals received for this sector alone, requesting over 450 Meuros

    • ca 40 Integrated Projects / Networks of Excellence,

    • involving some 1500 participants from 45 countries

    • NoEs 30-40 partners 2/3 persons each

    • on topics including:

      • Semantic Web technology and applications

      • advanced multimedia content annotation / data mining e.g. using machine learning

      • context-aware (mobile) services

      • semantic search engines (QA dialogue, multimedia)

      • agent technology, inferencing and reasoning methods.


Conclusion l.jpg
Conclusion

  • Certain number of ground conditions to be met before the vision can be realised

  • E.U. can support through:

    • policy actions e.g. e-Europe

    • RTD to explore applications, complement W3C

  • FP5 projects ongoing and FP6 in pipeline

  • Next steps:

    • Prepare for Call 2 - now open.

    • Prepare for 2004-2005 workprogramme.
