This class addresses the design and creation of multimedia databases (image, video, music and text databases), data mining and semantic associative processing. The most important objective of this lecture is to develop knowledge and skills for designing and creating multimedia databases and multimedia systems with experimental practice. It is essential to study how to analyze, store, retrieve and integrate media data (image, video, music and text) in a database system environment. An actual database system is used to create experimental multimedia databases and applied it to WWW system environments. We also design a meta-level multimedia system with data miniing processes for new-multimedia creation.
