{{Short description|Artificial intelligence project}}

'''Open Mind Common Sense''' ('''OMCS''') is an [[artificial intelligence]] project based at the [[Massachusetts Institute of Technology]] (MIT) [[MIT Media Lab|Media Lab]] whose goal is to build and utilize a large [[commonsense knowledge (artificial intelligence)|commonsense knowledge base]] from the contributions of many thousands of people across the Web. It has been active from 1999 to 2016.

Since its founding, it has accumulated more than a million English facts from over 15,000 contributors in addition to knowledge bases in other languages. Much of OMCS's software is built on three interconnected representations: the natural language corpus that people interact with directly, a semantic network built from this corpus called '''ConceptNet''', and a matrix-based representation of ConceptNet called '''AnalogySpace''' that can infer new knowledge using [[dimensionality reduction]].<ref name="aaai" /> The knowledge collected by Open Mind Common Sense has enabled research projects at MIT and elsewhere.
