Overview

Welcome to the Open Multilingual Wordnet (OMW) project. The goal of this project is to make it easy to use wordnets in multiple languages. We have been working for many years to make a shared format and link the wordnets together. OMW and its components are open: they can be freely used, modified, and shared by anyone for any purpose.

There is a new OMW browser available (🦢 Cygnet --- a Network of Signs). Currently there are 60 wordnets for 49 languages, we are adding more as they become available. You can see the full list of wordnets in Cygnet by clicking the wordnets tab.

If you use these wordnets, please cite the original projects who created them, if you got value from this aggregation/normalization, please cite Bond and Paik (2012).

There are two older versions of the OMW.

• OMW Version 1 links hand created wordnets and automatically created wordnets for over a 150 languages through the Princeton Wordnet of English.
• OMW Version 2, which provides a different interface. Both it and Cygnet use the Collaborative Interlingual Index to link the wordnets together (Bond etal., 2016) .
• There is a fuller list of wordnets at the Global Wordnet Association's Wordnets in the World page.
