WHAT ARE THE DIGITAL
HUMANITIES?
1/10/2011 CUbRIK Presentation 7

9. CUbRIK Summer School 2014
What are the digital humanities?
Digital Humanities is the application of
computational methods and tools for the
humanities
but
„[…] the issue would be not how much
computing we need for getting the answers, but
how much computer science needs us to ask
the right questions.“

25. CUbRIK Summer School 2014
Challenges
 Detection and identification of
identities/places/events in time
 Verification of identities/places/events in time
 Analysis of relationships (e.g. co-occurrences)
 Rights aware crawling and storage
 Verification of provenance and license
information
 Truth and provenance
1/10/2011 CUbRIK Presentation 24

26. CUbRIK Summer School 2014
Approach
 Crowd-sourced verification of detected faces
(false positives/negatives)
 Verification of identities through/places/events in
time social networks of experts
 Visual knowledge discovery/exploration
 Integrated rights aware crawling and storage
 Integrated license and provenance management

Motivation, gamification and
reputation
 Different levels of motivation for different tasks
 Face position validation -> Monetary incentives
 Face validation -> reputation gain
 Actions in the application can be rewarded
through the system and through other users
 Goal to motivate AND to capture reputation
1/10/2011 CUbRIK Presentation 27

29. CUbRIK Summer School 2014
Lessons learned
 No one truth in history but interpretation,
context and discussion
 Therefore need to represent ambivalence,
contradictions and discussion
 Close ties between data representation (Social
graph) and their original context (primary
sources)

Next step: evaluation
 4 week evaluation phase in July
 kick-off with a physical workshop in Luxembourg
 Closure with a virtual workshop
