2. Summary
1. The
future
of
Seman2c
Technologies
does
not
belong
to
the
current
Seman2c
Web

stack
2. It
may
belong
to
the
principles
underlying
it
3. For
that
there
are
s2ll
many
relevant
and
exci2ng
topics

3. A

Seman2c
Technologies

2001

in

(and
at

6. Use
Case
1-­‐
Social
Seman2c
Tagging
&
Collabora2ve
Ontology
Engineering
• Nega2ve
Experience:
– Social
/
Quan2ta2ve
data
(it
maZers
whether
a
statement
has
been
made
once
or
ten
2mes)
not
well
representable.
– World
is
not
ternary
(e.g.
<user,tag,resource,2me>),
hence
o]en
awkward
to
represent
and
query
– Statement
metadata
(creator,
visibility,
2mestamp)
awkward
to
manage
– Open
World
schema
seman2cs
hard
to
grasp
for
users
(SKOS
rescued
as
here)
and
frequent
source
of
programming
errors

7. Use
Case
2
–
Seman2c
Context
Management
• Managing
a
complex
representa2on
of
a
device’s
or
user’s
context
– E.g.
for
Ambient
Assisted
Living
&
Adaptable
user
interfaces
– Challenge
is
to
integrate
data
from
many
sensors,
to
deduce
informa2on
from
that
and
to
detect
and
act
on
predefined
situa2ons
• Nega2ve
Experience:
– Missing
(classical)
schema
language
to
specify
contracts
between
different
components
involved
in
managing
the
context
informa2on
(and
between
triple
store
and
object
oriented
world)
– Awkward
to
deal
with
uncertainty
– OWL
not
well
suited
to
formalize
the
needed
reasoning

8. Use
Case
3
–
Enterprise
Informa2on
Integra2on
• Crea2ng
a
long
term
plan
to
tackle
an
enterprise’s
eternal
informa2on
integra2on
challenges
• Nega2ve
Experience:
– (Currently
SW
tools
&
concepts
not
mature
enough
to
seriously
propose
this
to
companies)
– Mapping
arbitrary
RDBs
and
XMLs
to
RDF
o]en
results
in
awkward
representa2ons
and
unclear
benefit
– OWL
does
not
help
in
any
way
I
can
see

9. Why

visions

11. ‚Underlying

/
Core
Ideas
• Complex
Databases:
pushing

boundaries
complex
informa2on
processing
in
databases
• (Partly)
Domain
Knowledge
Agnos:c
Systems:
Taking
domain
knowledge
out
of
code
and
db
schema
and
make
it
changeable
at
run2me
• Collabora:ve
Domain
Knowledge:
Make

models
editable,
shareable
and

• Using

to
