Cultural differences play a very important role in matching ICT in- teraction to the expectations of users from different national and cultural back- grounds. But to date, there has been few research as to the extent of such differ- ences, and how to produce software that takes into account these differences. Considering the third wave of HCI research on context, involving the intangible aspects of the interaction with users and ICT solutions, like culture, we are studying these issues using a unique resource: Common Sense knowledge bases in different languages. We have knowledge bases containing millions of sen- tences describing people and everyday activities, collected from volunteer Web contributors, in three different cultures: Brazil, Mexico and the USA. It is de- scribed the experiences with these knowledge bases. Though preliminary, we hope that our work will contribute to software that takes better account of such differences, and fosters inter-cultural collaboration
