Data Commons

Data Commons is an open-source platform created by Google that provides an open knowledge graph, combining economic, scientific and other public datasets into a unified view. Ramanathan V. Guha, a creator of web standards including RDF, RSS, and Schema.org, founded the project, which is now led by Prem Ramaswami.

The Data Commons website was launched in May 2018 with an initial dataset consisting of fact-checking data published in Schema.org "ClaimReview" format by several fact checkers from the International Fact-Checking Network. Google has worked with partners such as the United Nations (UN) to populate the repository, which also includes data from the United States Census, the World Bank, the US Bureau of Labor Statistics, Wikipedia, the National Oceanic and Atmospheric Administration and the Federal Bureau of Investigation.

The service expanded during 2019 to include an RDF-style knowledge graph populated from a number of largely statistical open datasets. The service was announced to a wider audience in 2019. In 2020 the service improved its coverage of non-US datasets, while also increasing its coverage of bioinformatics and coronavirus. In 2023, the service relaunched with a natural-language front end powered by a large language model. It also launched as the back end to the UN data portal with Sustainable Development Goals data.
