This month's presentations:
Citation Needed: A Taxonomy and Algorithmic Assessment of Wikipedia's Verifiability
By Miriam Redi, Research, Wikimedia Foundation
Among Wikipedia's core guiding principles, verifiability policies have a particularly important role. Verifiability requires that information included in a Wikipedia article be corroborated against reliable secondary sources. Because of the manual labor needed to curate and fact-check Wikipedia at scale, however, its contents do not always evenly comply with these policies. Citations (i.e. reference to external sources) may not conform to verifiability requirements or may be missing altogether, potentially weakening the reliability of specific topic areas of the free encyclopedia. In this project, we aimed to provide an empirical characterization of the reasons why and how Wikipedia cites external sources to comply with its own verifiability guidelines. First, we constructed a taxonomy of reasons why inline citations are required by collecting labeled data from editors of multiple Wikipedia language editions. We then collected a large-scale crowdsourced dataset of Wikipedia sentences annotated with categories derived from this taxonomy. Finally, we designed and evaluated algorithmic models to determine if a statement requires a citation, and to predict the citation reason based on our taxonomy. We evaluated the robustness of such models across different classes of Wikipedia articles of varying quality, as well as on an additional dataset of claims annotated for fact-checking purposes.

Patrolling on Wikipedia
By Jonathan T. Morgan, Research, Wikimedia Foundation
I will present initial findings from an ongoing research study of patrolling workflows on Wikimedia projects. Editors patrol recent pages and edits to ensure that Wikimedia projects maintains high quality as new content comes in. Patrollers revert vandalism and review newly-created articles and article drafts. Patrolling of new pages and edits is vital work. In addition to making sure that new content conforms to Wikipedia project policies, patrollers are the first line of defense against disinformation, copyright infringement, libel and slander, personal threats, and other forms of vandalism on Wikimedia projects. This research project is focused on understanding the needs, priorities, and workflows of editors who patrol new content on Wikimedia projects. The findings of this research can inform the development of better patrolling tools as well as non-technological interventions intended to support patrollers and the activity of patrolling.----
