This class addresses the design and creation of multimedia knowledge bases (image, video, music and text knowledge-bases), data mining and semantic associative processing. The most important objective of this lecture is to develop knowledge and skills for designing and creating multimedia knowledge-bases 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 knowledge-base system environment. An actual knowledge-base system is used to create experimental multimedia knowledge-bases and applied it to WWW system environments. We also design a meta-level multimedia system with data mining processes for new-multimedia creation.
