Knowledge Discovery from XML Documents: First International Workshop, KDXD 2006, Singapore, April 9, 2006, Proceedings

The KDXD'06 (Knowledge Discovery from XML Documents) workshop is the first international workshop running this year in conjunction with the PAKDD'06 conference. The workshop provides an important forum for the dissemination and exchange of new ideas and, research related to XML data discovery and retrieval. The eXtensible Markup Language (XML) has become a standard language for data representation and exchange. With the continuous growth in XML data sources, the ability to manage collections of XML documents and discover knowledge from them for decision support becomes increasingly important. Due to the inherent flexibility of XML, in both structure and semantics, inferring important knowledge from XML data is faced with new challenges as well as benefits. The objective of the workshop is to bring together researchers and practitioners to discuss all aspects of the emerging XML data management challenges. Thus, the topics of interest included, but were not limited to: XML data mining methods; XML data mining applications; XML data management emerging issues and challenges; XML in improving knowledge discovery process; and Benchmarks and mining performance using XML databases. The workshop received 26 submissions. We would like to thank all those who submitted their work to the workshop under relatively pressuring time deadlines. We have selected 10 high quality full papers for the discussion and presentation in the workshop and for inclusion in the proceedings after peer-reviews by at least three members of the Program Committee. Accepted papers have been grouped in three sessions and allocated equal presentation time slots. The first session is on XML data mining methods of classification, clustering and association. The second session focuses on the XML data reasoning and querying methods. Query Optimization. And, the last session is on XML data applications of transportation and security . Special thanks go to the program committee members who shared their expertise and time to make KDXD'06 a success. The final quality of selected papers depends on their efforts. Last but least, we would like to thank the organizers of PAKDD 2006 for hosting KDXD'06
