TL;DR

This paper proposes a taxonomy of knowledge integrity risks in Wikipedia projects and introduces a preliminary set of indicators for assessing internal and external threats, including community demographics, content verifiability, and geopolitical factors. A key finding shows that low geographical diversity in editor contributions—particularly in Japanese and Egyptian Arabic Wikipedias—correlates with higher risk of misinformation, highlighting the need for a scalable, open-source Knowledge Integrity Risk Observatory to monitor and safeguard free knowledge platforms.

ABSTRACT

Wikipedia is one of the main repositories of free knowledge available today, with a central role in the Web ecosystem. For this reason, it can also be a battleground for actors trying to impose specific points of view or even spreading disinformation online. There is a growing need to monitor its "health" but this is not an easy task. Wikipedia exists in over 300 language editions and each project is maintained by a different community, with their own strengths, weaknesses and limitations. In this paper, we introduce a taxonomy of knowledge integrity risks across Wikipedia projects and a first set of indicators to assess internal risks related to community and content issues, as well as external threats such as the geopolitical and media landscape. On top of this taxonomy, we offer a preliminary analysis illustrating how the lack of editors' geographical diversity might represent a knowledge integrity risk. These are the first steps of a research project to build a Wikipedia Knowledge Integrity Risk Observatory.

Motivation & Objective

• To develop a systematic taxonomy of knowledge integrity risks across Wikipedia's 300+ language editions.
• To identify and operationalize measurable indicators for assessing internal (community/content) and external (geopolitical/media) threats to content reliability.
• To demonstrate the utility of these indicators through a case study on editor geographical diversity and its impact on knowledge integrity.
• To lay the foundation for a Wikipedia Knowledge Integrity Risk Observatory—a transparent, community-accessible dashboard for monitoring platform health.
• To support Wikimedia communities with data-driven tools to proactively detect and mitigate disinformation and systemic vulnerabilities.

Proposed method

• Developed a hierarchical taxonomy of knowledge integrity risks, differentiating between internal (community, content) and external (geopolitical, media) origins.
• Mapped existing literature and empirical studies to identify 10 risk categories, including community capacity, governance, demographics, and content verifiability.
• Proposed 14 core indicators across 7 categories, such as entropy of edit/view distributions by country, citation counts, and ORES scoring for article quality.
• Applied entropy-based metrics to analyze geographical diversity of editors and readers across large Wikipedia editions (e.g., English, Arabic, Japanese).
• Used longitudinal data (Nov 2018–Apr 2021) to compute and compare entropy values for edits and views by country of origin.
• Designed a framework for future expansion to include finer-grained metrics at page, category, or article levels, ensuring language-agnostic and interpretable indicators.

Experimental results

Research questions

• RQ1 How can knowledge integrity risks in multilingual Wikipedia projects be systematically categorized and measured?
• RQ2 To what extent does low geographical diversity in editor contributions correlate with increased risk of content bias or misinformation?
• RQ3 Which indicators are most informative for assessing the health of Wikipedia communities and content reliability across different language editions?
• RQ4 How can a scalable, open, and transparent monitoring system be designed to support Wikimedia communities in safeguarding knowledge integrity?
• RQ5 What role do external factors such as media coverage and democratic quality play in shaping knowledge integrity risks on Wikipedia?

Key findings

• The Arabic, English, and Spanish Wikipedias exhibit high geographical diversity in both edits and views, indicating global community participation.
• The Japanese Wikipedia shows extremely low entropy in view distribution, suggesting limited global readership and a higher risk of localized or nationalistic bias.
• The Egyptian Arabic Wikipedia displays a significant misalignment between high view entropy and low edit entropy, indicating potential foreign or bot-driven content consumption without local contribution.
• Cebuano and Waray-Waray Wikipedias show high edit entropy but low view entropy, likely due to globally distributed bot activity rather than organic community engagement.
• The Indonesian, Polish, Korean, and Vietnamese Wikipedias exhibit low geographical diversity in both edits and views, indicating potential systemic risks from limited global perspectives.
• The study demonstrates that entropy-based metrics of geographic distribution are effective early-warning indicators for knowledge integrity risks in large language editions.
