Copying and sharing ConceptNet

ConceptNet 5 comes largely from the hard work of hundreds of thousands of people who gave their time and knowledge for free. So ConceptNet is free as well, released under a choice of two Creative Commons licenses.

ConceptNet 5 Core: Attribution

The core of ConceptNet, including all the data in previous versions of ConceptNet and data collected from games, is available under the CC BY 3.0 license. See the terms of the license.

The practical effect of this license is that you can use ConceptNet data for any purpose, including commercial ones, as long as you give credit to its creators. If you are creating a copy or fork of ConceptNet, retaining this documentation page is sufficient. Otherwise, include this text in a prominent location in your derived work:

This work includes data from the ConceptNet 5 Core, which was compiled by the Commonsense Computing Initiative. ConceptNet 5 Core is freely available under the Creative Commons Attribution license (CC BY 3.0) from http://conceptnet5.media.mit.edu.

ConceptNet 5 Full: Attribution-ShareAlike

The most powerful version of ConceptNet 5 includes data derived from Wikimedia resources, including Wikipedia and Wiktionary. These are "share-alike" resources: you must make your copies, modifications, or derived works available under the same license terms.

The full version of ConceptNet 5 is thus available under the CC BY-SA 3.0 license. To give credit, we suggest this text:
