Preface

The understanding of data semantics in Web-based information systems is the object of intensive research efforts. The large volume of data on the Internet originates a need for accessing the semantic content of that information. Furthermore, it requires the personalizing of its search and integration to various types of users. Two approaches have been proposed in the research literature: integration of Web technologies with database technologies and use of meta-languages such as XML. These solutions offer highly structured or semi-structured data that allow users to perform queries at a higher semantic level. These also facilitate the dynamic personalization of Web-based applications. Therefore, it is now important to address the question of how one can efficiently query and search large collections of XML documents. And it is also necessary to find new solutions, 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 Systems (DNIS 2003) was he
