Wiki systems typically display article history as a linear sequence of revisions in chronological order. This representation hides deeper relationships among the revisions, such as which earlier revision provided most of the content for a later revision, or when a revision effectively reverses the changes made by a prior revision. These relationships are valuable in understanding what happened between editors in conflict over article content. We present methods for detecting when a revision… 
What did they do? Deriving high-level edit histories in Wikis
TLDR
This paper proposes a method for categorizing and presenting edits in an intuitive way and with a flexible measure of significance of each individual editor's contributions, by taking edit types into account.
Revision graph extraction in Wikipedia based on supergram decomposition
TLDR
A revision graph extraction method based on supergram decomposition in the document collection of near-duplicates is proposed and it is shown that this method can effectively perform the task than existing methods.
Revision Graph Extraction in Wikipedia Based on Supergram Decomposition and Sliding Update
TLDR
This paper proposes a revision graph extraction method based on supergram decomposition in the document collection of near-duplicates and shows that this method can effectively perform the task than existing methods.
WikiReviz: An Edit History Visualization for Wiki Systems
TLDR
This demo describes the motivation and features of WikiReviz, a visualization system for analyzing edit history in Wikipedia and other Wiki systems that reconstructs the derivation relationships among revisions precisely and efficiently by revision graph extraction.
Contropedia - the analysis and visualization of controversies in Wikipedia articles
TLDR
The proposed platform, Contropedia, builds on state of the art techniques and extends current metrics for the analysis of both edit and discussion activity and visualizes these both as a layer on top of Wikipedia articles as well as a dashboard view presenting additional analytics, for a deeper understanding of the substance, composition, actor alignment, trajectory and liveliness of controversies on Wikipedia.
Recognizing contributions in wikis: Authorship categories, algorithms, and visualizations
TLDR
It is demonstrated that the proposed automated techniques can estimate fairly accurately the quantity of editors’ contributions across various authorship categories, and that the visualizations introduced can clearly convey this information to users.
Recognizing contributions in wikis: Authorship categories, algorithms, and visualizations
TLDR
It is demonstrated that the proposed automated techniques can estimate fairly accurately the quantity of editors' contributions across various authorship categories, and that the visualizations introduced can clearly convey this information to users.
Societal Controversies in Wikipedia Articles
TLDR
Contropedia is presented, a tool that augments Wikipedia articles and gives insight into the development of controversial topics and an efficient language agnostic measure based on the edit history that focuses on wiki links to easily identify which topics within a Wikipedia article have been most controversial and when.
Revisiting reverts: accurate revert detection in wikipedia
TLDR
An improved algorithm for the detection of reverts based on word tokens added or deleted based on MD5 hash values is introduced, showing considerable gains in accuracy and coverage and arguing for a positive trade-off, in certain research scenarios, between these improvements and the algorithm's increased runtime.
Modeling user reputation in wikis
TLDR
Pparse and mine the entire English Wikipedia history pages in order to extract detailed user edit patterns and statistics and derive three computational models of a user's reputation, which are validated using ground‐truth Wikipedia data associated with vandals and administrators.

Structuring wiki revision history
TLDR
The proposed revision history of a wiki page is represented as a tree of versions, with every edge in the tree given a weight, called adoption coefficient, indicating similarity between the two corresponding page versions.
A Nonlinear Representation of Page History in P2P Wiki System
TLDR
A non linear representation for the page history in P2P wiki systems is introduced; the user can explore the page versions that resulted under the user’s control or produced by the server in case of merging concurrent modifications.
Visual Analysis of Controversy in User-generated Encyclopedias
  • U. Brandes, J. Lerner
  • Computer Science
    2007 IEEE Symposium on Visual Analytics Science and Technology
  • 2007
TLDR
It is shown that a visual analysis of the "who revises whom"- network gives deep insight into controversies, and a set of analysis and visualization techniques are proposed that reveal the dominant authors of a page, the roles they play, and the alters they confront.
Studying cooperation and conflict between authors with history flow visualizations
TLDR
This paper investigates the dynamics of Wikipedia, a prominent, thriving wiki, and focuses on the relevance of authorship, the value of community surveillance in ameliorating antisocial behavior, and how authors with competing perspectives negotiate their differences.
Visualizing Co-Authorship Networks in Online Wikipedia
  • R. Biuk-Aghai
  • Computer Science
    2006 International Symposium on Communications and Information Technologies
  • 2006
TLDR
The notion of using co-authorship of articles to determine relationship between articles is introduced, and the WikiVis information visualization system is presented which visualizes this and other types of relationships in the Wikipedia database in 3D graph form.
Can you ever trust a wiki?: impacting perceived trustworthiness in wikipedia
TLDR
Examination of whether a visualization that exposes hidden article information can impact readers' perceptions of trustworthiness in a wiki environment suggests that surfacing information relevant to the stability of the article and the patterns of editor behavior can have a significant impact on users' trust across a variety of page types.
Lifting the veil: improving accountability and social transparency in Wikipedia with wikidashboard
TLDR
A social dynamic analysis tool called WikiDashboard is described which aims to improve social transparency and accountability on Wikipedia articles, and early reactions from users suggest that the increased transparency afforded by the tool can improve the interpretation, communication, and trustworthiness of Wikipedia articles.
Computing trust from revision history
TLDR
This paper explores ways of utilizing the revision history of an article to assess the trustworthiness of the article and uses this revision history-based trust model to assess a chain of successive versions of articles in Wikipedia and evaluated the assessments produced by the model.
A content-driven reputation system for the wikipedia
TLDR
The results show that the notion of reputation has good predictive value: changes performed by low-reputation authors have a significantly larger than average probability of having poor quality, as judged by human observers, and of being later undone, as measured by the algorithms.
He says, she says: conflict and coordination in Wikipedia
TLDR
The growth of non-direct work in Wikipedia is examined and the development of tools to characterize conflict and coordination costs in Wikipedia are described, which may inform the design of new collaborative knowledge systems.
