Databases in Networked Information Systems Third International Workshop, DNIS 2003, Aizu, Japan, September 22-24, 2003, Proceedings

The understanding of data semantics in Web-based information systems is the object of intensive research e'orts. The large volume of data on the Internet originatesaneedforaccessingthesemanticcontentofthatinformation. Furth- more, it requires the personalizing of its search and integration to various types of users. Two approacheshave been proposed in the research literature: integ- tion of Web technologies with database technologies and use of meta-languages such as XML. These solutions o'er highly structured or semi-structured data that allow users to perform queries at a higher semantic level. These also faci- tate thedynamic personalizationof Web-basedapplications. Therefore, it is now important to address the question of how one can e'ciently query and search large collections of XML documents. And it is also necessary to ?nd new so- tions, both to support dynamic architectures for Web-based applications and to model users' search and result presentation criteria. The third international workshop on Databases in Networked Information S- tems (DNIS 2003) was held on September 22-24, 2003 at the University of Aizu in Japan on the occasion of its 10th anniversary. The workshop program included research contributions, and invited contributions. The session on Web IntelligenceincludedinvitedpapersbyProfessorJimingLiuandProfessorCyrus Shahabi. The session on Information Interchange and Management Systems - cluded invited papers by Professor Tosiyasu L. Kunii, Professor Elisa Bertino, and ProfessorMarc Sifer. The session on Information Interchange Among Cyber CommunitieshadinvitedpapersbyProfessorToyoakiNishida, ProfessorMasaru Kitsuregawa, and Dr. Umeshwar Dayal. Finally the session onKnowledge - - notation and Visualization included theinvited contributionby ProfessorDaniel Keim.
