2. Mo0va0on
and
Challenges
• Vast
of
scien0fic
publica0ons
available
online
– proprietary
interfaces
with
poor
context
overview
– costs
for
full
access
required
• Researchers
– use
Social
Media
to
communicate
about
their
work
–
have
interests
on
events,
persons
and
resources
from
research
related
to
them
• Digital
publica0on
archives
available
as
Linked
Data
• Lack
of
analy0c
services
and
adequate
visualiza0ons

3. Goals
Make
the
most
of
the
wealth
of
resources
for
research:
through
rela0ng
and
aligning
scholar
profiles
with
the
online
available
resources,
publica0ons,
and
other
scholar's
profiles.
Provide
a
interface
for
visual
explora0on
and
search
based
upon
commonali0es
derived
from
this
alignment

4. Alignment
Concept

6. Finding
Commonali0es
• Real-­‐0me
keyword
disambigua0on
of
entry
results
• Finding
rela0ons
between
the
entered
keywords
through
the
EiCE
• Addi0onally
enhancement
– social
media
profile
as
search
entry
point
– Expansion
of
results
over
radial
interface

7. ResXplorer
• “ResXplorer”
is
aggregated
interface
for
search
and
explora0on
of
the
underlying
Linked
Data
Knowledge
Base
• Radial
Interface
with
clickable
en00es
differing
through
color,
size
and
shape
• Resides
on
EiCE
Engine
(
our
prior
work
on
path
finding
between
resources
in
seman0c
en0ty
graphs)
• Interface
adapts
the
explora0on
state
and
focused
en0ty
is
always
central.
The
distance
and
posi0on
of
other
en00es
is
defined
by
affinity
ranking
algorithm.

Evalua0on

10. Measure
Links discovered along traversing path of algorithm which lead to scientific resources
(publications, persons and events) relevant for one of the both authors represent true
positives.

• Short

domain
• Likert

17. Conclusions
• ResXplorer
allows
researchers
to
interac0vely
explore
rela0ons
between
the
resources
and
en00es
like
events,
places,
publica0ons
or
persons
related
to
their
work
and
discover
commonali0es
between
them
• Finding
commonali0es
tends
to
reach
high
precision
which
does
not
depend
from
the
length
of
search
path,
and
the
count
of
found
commonality
links
• ResXplorer
interface
is
according
to
“percieved
usefullness”
survey
made
with
target
users
meant
primarily
to
explore
rela0on
between
research
en00es
