This workshop will tackle misinformation and disinformation on Wikimedia platforms, especially Wikipedia, focusing on African content. Participants will learn fact-checking strategies, source verification, and misinformation detection through practical exercises. Techniques include reverse image search (Yandex, InVID WeVerify, Google Reverse Image Search) and using Hive for AI-generated content verification and ClaimBuster for claim detection. The session will also cover open-source intelligence (OSINT) tools for building threat-actor databases and reveal how extremist groups use digital strategies to evade detection, aiming to equip the African Wikimedia community with the skills to ensure content accuracy and integrity.
