<div>Data analysis is experiencing two changes. Firstly, the data used in analysis is changing from mostly domain-specific data to data from multiple, often unfamiliar, sources; and secondly, data analysis practitioners are changing from only computer scientists or statisticians and other technical experts to experts in the application domains. It has therefore become increasingly important to provide tools that will help user to discover the useful data and make use of them in their analysis tasks. This talk will discuss the possibility in providing such tools that are collectively called "intelligent data analysis system”, and introduce several preliminary attempts.</div>
