Note publique d'information : ThePaci?c-AsiaConferenceonKnowledgeDiscoveryandDataMining(PAKDD) has been held every
year since 1997. This year, the eighth in the series (PAKDD 2004) was held at Carlton
Crest Hotel, Sydney, Australia, 26–28 May 2004. PAKDD is a leading international conference
in the area of data mining. It p- vides an international forum for researchers and
industry practitioners to share their new ideas, original research results and practical
development experiences from all KDD-related areas including data mining, data warehousing,
machine learning, databases, statistics, knowledge acquisition and automatic scienti?c
discovery, data visualization, causal induction, and knowledge-based systems. The
selection process this year was extremely competitive. We received 238 researchpapersfrom23countries,whichisthehighestinthehistoryofPAKDD,
and re?ects the recognition of and interest in this conference. Each submitted research
paper was reviewed by three members of the program committee. F- lowing this independent
review, there were discussions among the reviewers, and when necessary, additional
reviews from other experts were requested. A total of 50 papers were selected as full
papers (21%), and another 31 were selected as short papers (13%), yielding a combined
acceptance rate of approximately 34%. The conference accommodated both research papers
presenting original - vestigation results and industrial papers reporting real data
mining applications andsystemdevelopmentexperience.Theconferencealsoincludedthreetutorials
on key technologies of knowledge discovery and data mining, and one workshop focusing
on speci?c new challenges and emerging issues of knowledge discovery anddatamining.ThePAKDD2004programwasfurtherenhancedwithkeynote
