Reconciling Inconsistent Data in Probabilistic XML Data Integrationation quality. Typically, in order to remove inconsistencies, i.e. conflicts between data, data cleaning (or repairing) procedures are applied. In this paper, we present a probabilistic XML data integration setting. A probability is assigned to each data source and its probability models the . of th

Load Shedding in MavStream: Analysis, Implementation, and Evaluationquirements throughout the life of a data stream, result characteristics need to be monitored at runtime and adjustments made continuously. It has been shown that in a DSMS, switching scheduling strategies at runtime can change tuple latency requirements. DSMSs also experience significant fluctuation

Virtual Forced Splitting, Demotion and the BV-Treeves, thereby guaranteeing that only one path from the root need be searched to find any point in the tree. This reduces occupancy of forcibly split pages, possibly down to single entries in pathological cases. Freeston introduced a novel approach to obtaining the benefits of forced splitting while a

Ranking for Approximated XQuery Full-Text Queries’s informational needs. Using an approximated semantics requires however a mechanism for calculating a score for each resulting tree, and an algorithm for efficiently finding the best results. Both these issues are explored in this paper. We present algorithms for query evaluation that uses a . appr

Role Based Access to Support Collaboration in Healthcarelted in the widespread creation of MultiDisciplinary care Teams (MDTs). These teams consist of practitioners with a variety of specialties often sited at different locations [1, 2]. This collaborative approach has led to a significant shift in information needs. However, existing information systems

A Peer-to-Peer Database Serverresponse time, and in the worst case the server may be unable to provide any service at all..In the domain of file-sharing, the problem of server overloading has been successfully addressed by the use of Peer-to-Peer (P2P) techniques in which clients (peers) supply files – or pieces of files – to ea
