Databases in networked information systems

by DNIS 2003 (2003 Aizu-han, Japan)

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 interna
