A new tool to visualise groups of Wikipedia articles, analyse and monitor them, support the work of volunteers, researchers and GLAMs, and create knowledge landscapes.

Wikipedia is a mainstream source of information accessible in 342 languages, with 65 million articles and over 25 billion views per month: it is the largest existing open collaborative peer-production platform, with 124 million registered users and over 600,000 contributors, actively involved in producing and disseminating open knowledge. Supporting those active communities of volunteers, researchers and GLAMs in evaluating and producing quality knowledge responds to a societal need and triggers research in design, boosting active citizenship and democratic processes.

The prototype we present will be available for Wikipedia articles in English, Spanish, French, and Italian. It will focus on climate change and sustainability articles to assess current coverage and test interventions. Once developed, the tool will be adaptable to any topic, starting from Wikidata and Wikipedia categories.

Through the tool:
* Volunteers can explore the most viewed and edited Wikipedia articles and assess which ones to improve, whether a quality version exists in another language, if images are missing, if the topics are controversial, or if there are specific issues.
* Researchers can analyse how a topic is presented on Wikipedia through multiple visualisations. They can assess the most viewed and edited articles, the evolution of content over time and the links among articles. They can also visualise which Wikidata items related to a specific topic lack an article.
* Institutions engaged in Wikimedia projects and initiatives can evaluate and monitor the quality of topics on Wikipedia and how they evolve. Use visualisations as a communication tool to explain the relevance and impact of initiatives contributing to Wikimedia projects.
* GLAMs can explore how topics central to their mission are documented on Wikipedia, contribute with their data and expertise to improve them, and monitor their impact in terms of knowledge production and visibility.

This participatory and visual analytics project and free and open software tool is developed in the framework of the international research project “Visual Analytics for Sustainability and Climate Change: Assessing online open content and supporting community engagement. The case of Wikipedia" (2025-2029), led by the University of Applied Sciences and Arts of Southern Switzerland (SUPSI), in collaboration with Wiki Education Foundation, Wikimedistas de Uruguay, Wiki in Africa and Open Climate Campaign, with the endorsement of Wikimedia Italia, the support of the Swiss National Science Foundation (SNSF, grant n. 10.003.183) and the engagement of many Wikipedia and Wikidata volunteers.
