Emerging Technologies in Knowledge Discovery and Data Mining
The techniques of knowledge discovery and data mining (KDD) have rapidly developed along the signi?cant progress of the computer and its network te- nologies in the last two decades. The attention and the number of researchers in this domain continue to grow in both international academia and industry. The Paci?c-Asia Conference on Knowledge Discovery and Data Mining (PAKDD) is a worldwide representative international conference on the research areas of KDD. Under the currentspreadof KDD techniquesin our society,PAKDD 2007 invited the organizers to an industrial track on KDD techniques and, moreover, called for enterprising proposals of workshops on novel and emerging topics in KDD studies. The PAKDD industrial track and the PAKDD workshops both attracted more than 350 paper submissions from 22 countries in total, of which only 81 high-quality papers were accepted after strict reviews. The conference provided many informal and vibrant opportunities for researchers and industry practitionersto sharetheir researchpositions, originalresearchresultsand pr- tical development experiences on speci?c new challenges, emerging issues, new technology trends and solutions to real-world problems.

Sixty-twoo- standing papers in the industrial track and the workshops were further selected, among the 81 paper presentations, under even more rigorous reviews by the - ganizers, and these papers were carefully brushed up and included in this po- proceedings volume. The ?rst part of this volume contains ten outstanding papers presented in the industrial track.
