The research of multimedia data mining in digital library

Data mining and knowledge discovery provides us a new way to resolve the problem that we can´t make the best of increasing huge data. Data mining is the key technology in digital library. People need not only to retrieve the information of text but also to manage and retrieve video information. It makes the multimedia data mining the hotspot of research.

And it can also provide us the ability of decision-supporting to resolve the problem. This paper discusses the basic theories of Data Mining and Knowledge Discovery and presents the process, methods and data representation of multimedia data mining. Then it analyze the feature of information retrieval and multimedia mining engine(MME).
