22. The REVEAL approach
R&D dealing with, among others
Contributor
• Who contributed what?
• What did they do in the past?
• Who follows him/her? With whom do they interact? How? What’s their
reputation? Tustworthiness?
• How long did social accounts exist? What can be derived from it?
• Links to profile pages, affiliates, contact data?
• ...
23. The REVEAL approach
R&D dealing with, among others
Content
• Image analysis (checks, similarity search, manipulations, comparisons)
• Text analysis (stylometry, accuracy, comparisons)
• (Rudimentary video analysis > not in focus)
• ...
24. The REVEAL approach
R&D dealing with, among others
Context
• Who says what how about the same / related topic, and what is being
said how?
• Who are the people contributing? What did they do previously? How did
they act/react? Can patterns be detected?
• How can information be connected sensibly and beneficially with other
resources. (E.g.: correlate Social Media activities with information from
disaster management / relief agencies / natural catastrophe centres etc)
• ...
