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:

It is a long

term haul before ICT becomes a general
utility comparable with energy or transport networks.

Tomorrow: Ambient Intelligence?

aware devices, sensors, etc



Broadband, wireless multimedia



Billions of tagged objects

Seamless interoperability



Internet parallels mass media

Narrow bandwidth



Objects are just objects



Web “dumb, boring and isolated”



Applications “islands” eWork/eGov



Internet users “only” in millions

“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)

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.

Content market dynamics

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.

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

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.

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)


Objective:



RTD should aim to :


develop
semantic
-
based

and
context
-
aware

systems which
can
acquire, organise, process, share and use the
knowledge

embedded in
multimedia content


maximise
automation

of the complete
knowledge lifecycle


achieve semantic
interoperability

between Web resources
and services.

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

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

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
