Researchers at the Universities of G..ttingen and Frankfurt and the Jo..ef Stefan Institute in Ljubljana have developed an approach that can recognize fake news, even when the news contents are repeatedly adapted. The new approach can be used, for example, in market surveillance to temporarily suspend the trading of affected stocks. It is also possible that it could be used for criminal prosecutions in the future. The approach is already known in principle from its use by spam filters, but the key problem with the current methods is that fraudsters continuously adapt the content and avoid certain words that are used to identify the fake news.
