Over the past few years, research and development in data mining has made great progress. Many successful applications have been reported in  journals and  conferences. In  general, data mining systems typically help businesses expose previously unknown patterns in their databases. 
It has now been recognized that mining for information and knowledge from large databases and documents will be the next revolution in database systems. It is considered  very  important  tomajor cost savings and potential revenue  increase  with immediate applications in business, decision systems, information management, communication, scientific research and technology development. Since data mining is still a relatively new research field, a great deal of research and applications are still in progress.

In recent years, advanced data mining techniques have been developed rapidly. More and more sophisticated techniques, such as association rules, fuzzy data mining, genetic algorithms applied to data mining, utility mining etc. have been proposed and many of them have already been deployed in many real-world applications. The  major goal of this special session is to bring together the researchers in  the  data mining field to illustrate  its  pressing  actual  needs, demonstrate challenging research issues, and  exchange the state-of-the-art research and development.
