§16§The annual international conference on Database and Expert Systems Applications (DEXA) is now well established as a reference scientific event. The reader will find in this volume a collection of scientific papers that represent the state of the art of research in the domain of data, information and knowledge management, intelligent systems, and their applications. The 17th instance of the series of DEXA conferences was held at the Andrzej Frycz Modrzewski Cracow College in Kraków, Poland, during September 4-8, 2006. Several collocated conferences and workshops covered specialized and complementary topics to the main conference topic. Four conferences ? the 8th International Conference on Data Warehousing and Knowledge Discovery (DaWaK), the 7th International Conference on Electronic Commerce and Web Technologies (EC-Web), the 5th International Conference on Electronic Government (EGOV), and the Third International Conference on Trust, Privacy, and Security in Digital Business (Tr §16§ustBus) ? and 14 workshops were collocated with DEXA. The whole forms a unique international event with a balanced depth and breadth of topics. Its much-appreciated conviviality fosters unmatched opportunities to meet, share the latest scientific results and discuss the latest technological advances in the area of information technologies with both young scientists and engineers and senior world-renown experts. This volume contains the papers selected for presentation at the conference. Each submitted paper was reviewed by three or four reviewers, members of the Program Committee or external reviewers appointed by members of the Program Committee. §04§XML I.- Data and Information I.- Invited Talk DEXA Conference.- XML II.- Data and Information II.- XML III.- Data and Information III.- Datamining and Data Warehouses.- Database Applications I.- XML IV.- Data and Information IV.- XML V.- Data and Information V.- Datamining and Data Warehouses.- Database Applications II.- WWW I.- Bioinformatics.- WWW II.- Process Automation and Workflow.- Knowledge Management and Expert Systems.- Database Theory I.- Query Processing I.- Database Theory II.- Query Processing II.- Database Theory III.- Knowledge Management and Expert Systems.- Database Theory IV.- Privacy and Security.- Database Theory V. §04§c Replication Scheme for Mobile-P2P Networks.- Datamining and Data Warehouses.- Lossless Reduction of Datacubes.- Multivariate Stream Data Classification Using Simple Text Classifiers.- Location-Based Service with Context Data for a Restaurant Recommendation.- Cascaded Star: A Hyper-Dimensional Model for a Data Warehouse.- Database Applications II.- Using JDOSecure to Introduce Role-Based Permissions to Java Data Objects-Based Applications.- A Forced Transplant Algorithm for Dynamic R-tree Implementation.- An Approach for a Personal Information Management System for Photos of a Lifetime by Exploiting Semantics.- Topic Distillation in Desktop Search.- WWW I.- Interactions Between Document Representation and Feature Selection in Text Categorization.- WebDriving: Web Browsing Based on a Driving Metaphor for Improved Children's e-Learning.- Semantic Wikis for Personal Knowledge Management.- Bioinformatics.- Integration of Protein Data Sources Through PO.- 3D Protein Structure Matching §04§ by Patch Signatures.- WWW II.- Segmented Document Classification: Problem and Solution.- User Preference Modeling Based on Interest and Impressions for News Portal Site Systems.- Cleaning Web Pages for Effective Web Content Mining.- Process Automation and Workflow.- An Applied Optimization Framework for Distributed Air Transportation Environments.- On the Completion of Workflows.- Concurrency Management in Transactional Web Services Coordination.- Acquisition of Process Descriptions from Surgical Interventions.- Knowledge Management and Expert Systems.- Adaptive Policies in Information Lifecycle Management.- Implementation and Experimentation of the Logic Language .- Converting a Naive Bayes Models with Multi-valued Domains into Sets of Rules.- Hypersphere Indexer.- Database Theory I.- Distributed Continuous Range Query Processing on Moving Objects.- Optimal Route Determination Technology Based on Trajectory Querying Moving Object Database.- Efficient Temporal Coalescing Quer
