Welcome to Open Mind Common Sense!

Welcome! We've changed some things recently, so check out the site blog. You can finally flag statements with bad grammar; soon we'll let you fix them.

Computers don't currently know the basic things about the world that we consider "common sense." Here, you can help build a database of such knowledge in simple English sentences. The computer will analyze these sentences to connect concepts and draw new conclusions from the things you teach it.

Getting started

To browse, type a word or two into the "Search" box, click a link on the sidebar, or see the highest-rated statements.

The big picture

This site is the current implementation of Open Mind Common Sense, a project that enables computers to learn general knowledge from ordinary people over the Web. It is the product of ongoing research by the Commonsense Computing Initiative at the MIT Media Lab. You can find related projects that other groups are working on at OpenMind.org.

The information collected by this site becomes part of ConceptNet, an open-source, multilingual semantic network of general knowledge.

Languages

We currently have significant amounts of data in English and Portuguese, and working on expanding to other languages.
