The EC funded research project GEMINI (Generic Environment for Multilingual Interactive Natural Interfaces) has two main objectives: On the one hand the development and implementation of a platform able to produce user-friendly interactive multilingual and multimodal dialogue interfaces to databases with a minimum of human effort and on the other hand the demonstration of the platform's efficiency through the development of two different applications using this platform. The platform consists of different assistants that help the user to semi-automatically generate dialogue applications. Its open and modular architecture simplifies the adaptability of generated applications to different use cases.
