public opinion
Wikipedia’s most visible side
Behind the scenes: talk pages (>10k comments, 32 archived pages)
Complete edit history log (>17k revisions)
Contropedia aims to:
● make this huge volume of information easily accessible
● unveil negotiations behind encyclopaedic content
● allow users to follow the development of individual topics
Layer view
● which are the most disputed concepts?
● where are controversies located in the article?
● wiki links as focal points○ the hotter the color, the more controversial
the element (wiki link)

Controversiality measure
● count edits to sentences including a wiki link
● only consider substantive disagreeing edits:○ substantive -> no vandalism or anti-vandalism○ disagreeing -> delete some content
● language agnostic approach○ based only on user activity
Dashboard view
● ranking of the most controversial elements within the article
● timeline shows when each element was most disputed
● elements that are not present (as wiki links) in the current version of the article are struck through
Detailed view
● all the edits involving a specific element○ edits in chronological order○ content added and deleted in each edit
● Optionally shown also related comments from the talk page
