Dear all, we have launched the BabelNet ANnotation Group (BANG) initiative. You will be able to contribute to BabelNet by providing missing lemmas, definitions and example in your language and pictures for the synsets which do not have a visual representation! All the data will be made freely available with a CC0 license!

To join the group, enter the login area http://babelnet.org/login, go to account details and set "BANG" to yes, save, then go to the annotation tab and enjoy!
