„[…] 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.“http://whatisdigitalhumanities.com, Domenico Fiormonte, Université Roma Tre
Digital Humanities is the application of
computational methods and tools for the
humanities

Challenges
Detection and identification ofidentities/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 licenseinformation
Truth and provenance
24
CUbRIK Summer School 2014
Approach
Crowd-sourced verification of detected faces(false positives/negatives)
Verification of identities through/places/events intime social networks of experts
Visual knowledge discovery/exploration
Integrated rights aware crawling and storage
Integrated license and provenance management

Discursive interface
CUbRIK Presentation 26
Voting (ref. Stackoverflow) is supported
through source referencing and
explanations. Solutionspace
Shared visualization
Multipleperspectives
Problem space
CUbRIK Summer School 2014
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 rewardedthrough the system and through other users
Goal to motivate AND to capture reputation
27
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 (Socialgraph) and their original context (primarysources)
28
CUbRIK Summer School 2014
Next step: evaluation
4 week evaluation phase in July
kick-off with a physical workshop in Luxembourg
Closure with a virtual workshop
