I'm busy - new Java project

I'm quite busy now, while setting up new project. It will be Medical Diagnostic Expert System using machine learning algorithms. I've got legacy applications preceding that project, that could be used for their core algorithms implementation. Besides that, the whole application must be build from scratch, to meet new requirements. I'm working now on data gathering services and user interface for experts modules. It is designed as web application, implemented in Java and using Spring framework.
