In fact, our project is just a digital library project. DRIS is its main part. Another part is Mylibrary@HUST, a intellitent search system, which will directly answer all your question in the future.

There has been some excellent systems in some libraries. But the main disadvantage of these systems lie that its knowledge database is too small and can only answer few questions.
