‘YAGO – A High-Quality Knowledge Base is a computer studies project that has been underway for 15 years. It is one of the pioneers of the semantic Web and is viewed as a reference in the field. Its researchers have constructed a knowledge base based on Wikipedia and Wikidata which can be used by many tools to provide knowledge about the real world, particularly in the context of artificial intelligence applications. Methods have been integrated to process and clean the input data and thus provide a very highly interoperable quality service that is a core component of many Linked Open Data projects. The project involves a team of 3 people from Telecom Paris and the Max Planck Institute for Informatics in Germany led by Fabian Suchanek (Telecom Paris).
