ClaimsKG - A Knowledge Graph of Fact-Checked Claims (September, 2026)
Listed in GESIS Data Archive
ClaimsKG is a knowledge graph of fact-checked claims collected from multiple fact-checking organisations, providing structured information about claims, their veracity assessments, sources, reviewers, and entities.
Description
In this work, we present the latest release of ClaimsKG, which substantially extends its coverage while improving data quality, annotation, and the underlying data-generation pipeline. The new release is provided in two complementary data formats.
The TSV data offer contains 104,334 fact-checked claims collected from participating fact-checking websites, covering their available content from website inception through July 2026 in raw data format. The TTL data offer, in contrast, provides the knowledge-graph representation and contains 32,148 claims published between January 2023 and July 2026, extending the RDF data beyond the coverage of the previous release. The release incorporates 10 fact-checking websites, including the newly added French version of Africa Check.

It also reflects changes in the availability and naming of sources: Polygraph has changed its name to Voice of America, while Fatabyyano, AFP Fact Check, and AFP Factuel were removed due to anti-scraping measures that prevented reliable data collection. To improve interoperability across fact-checking sources, we introduce an LLM-based normalisation of fact-checking ratings into four categories: true, false, mixed, and other.
As a newly added property of the schema, Fact-checkers are explicitly represented using the `schema:reviewer` property, defined as `schema:Person`. The release further adds entity disambiguation for French claims along with English ones using Entity Fishing and DBpedia references. We additionally improve the scraping, preprocessing, and entity-extraction pipelines and optimise the generation process to support more efficient dataset maintenance.
Together, the expanded source coverage makes this release a more comprehensive resource for research on fact-checking, misinformation, claim analysis, and knowledge graph applications.
