A new AI-powered quote-checker called All Quotes has been launched by opinion site Euronews.

The new digital vertical, the result of a partnership between Euronews and AI start-up Storyzy, aims to tackle the problem of fake quotes and their role in spreading fake news.

Using a "quote verifier", users can establish whether quotes are "authentic, incomplete or dubious". Storyzy's claims a database of more than 15 million authentic quotes since 2015 - plus 96,000 from notable, historical figures - and is adding more than 50,000 new ones daily. The automated system creates an average of 400 new people pages daily.

The AI programme extracts quotes from Euronews and other news articles "all around the web", which are organised by speaker and occupation. Available in English, the two plan to extend the initiative to other languages.

Euronews chief executive Michael Peters says the aim is to empower people so they can make up their own minds: "At Euronews we are convinced that in a world of infobesity, it is imperative to put pluralism back at the centre of international debate."

Storyzy's Stan Motte says it took five years working on automated fact-checking technology to develop a reliable AI solution to solve a part of the fake news problem.

Its technology, based on natural language processing, is able to understand news articles, and extract speech "in the same way as humans". Clients include Gannett and the Mondadori Group, and Storyzy sells data to other platforms such as online advertising companies, using its "FakeRank" algorithm.

European and global international news channel Euronews was the subject of a deal last month which will see NBC News take a quarter share in the company, which is to be co-branded EuronewsNBC.
