We are developing many resources built around linguistic data, for languages around the world. At the Cultural Data hackathon, we are hoping for help with:
An application for translating museum exhibit information and signs in other public spaces (zoos, parks, etc) to multiple languages, so visitors can understand the exhibit no matter where they come from. We currently have a prototype for a similar application for restaurants.
Cultural datasets: we are looking for multilingual lexicons that we can incorporate into our db, to enhance the general vocabulary that we have for many languages.
UI design improvements. We have software, but it's not necessarily pretty. We need the eyes of designers to improve the user experience.
