Sessions
AletheiaFact.org is developing a disinformation triage system that leverages Wikidata's structured knowledge to automatically process, prioritize, and organize fact-checking verification requests. Our work-in-progress research demonstrates how Wikidata entity recognition and topic classification can transform chaotic public submissions into structured, prioritized workflows.
This presentation showcases our workflow; from initial request receipt through vandalism detection, entity/topic processing, priority assessment, and intelligent grouping with existing requests. We'll demonstrate live prototypes of "passes" that use Wikidata to identify duplicate claims, cluster related topics, and automatically flag high-priority verification needs based on entity significance and public interest patterns.
The research addresses a critical bottleneck in fact-checking: efficiently processing thousands of public verification requests while maintaining quality and avoiding duplication. By using Wikidata as the backbone for content organization, we're creating scalable approaches that could benefit the entire fact-checking ecosystem.
Wikidata makes amazing applications possible. In this panel we will hear from different projects using Wikidata's data for social good. They range from citizen participation, to fact checking to understanding the non-profit landscape better.
