When we do a search on the Internet, the search engine very often suggests the site of the community encyclopedia Wikipedia. It contains about 6.5 million articles by volunteer contributors, but how can we know if these are reliable, even though the sources of the articles are cited? Meta relied on Meta AI's research and advances to develop SPHERE, an open source model capable of automatically analyzing hundreds of thousands of citations at a time to check whether they actually support the corresponding claims, it recently published it on the Github platform. Meta said it is not partnering with Wikimedia, the foundation that runs Wikipedia, on this project. Its goal is to create a platform to help Wikipedia editors systematically spot citation problems and quickly correct the citation or the corresponding article content.
