At CJVT, we are aware how important knowledge sharing is. Therefore, we strive for open access to language data: Our resources and databases are accessible under open licences and are available to anyone. Additionally, we find it important to include our products’ users in the development of a tool or resource. Thus, we offer them the chance to contribute directly: e.g. with our responsive dictionary concept, by adding accentuation and pronunciation recordings, through (mobile) games … This gives us an important insight into the actual use of our tools. It also allows us to adapt our products to realistic user needs.
