Fast XML document filtering by sequencing twig patterns

Joonho Kwon, Praveen Rao, Bongki Moon, Sukho Lee
2009 ACM Transactions on Internet Technology  
. iFiST organizes the sequences into a dynamic hash-based index for efficient filtering, and exploits the commonality among user profiles to enable shared processing during the filtering phase.  ...  As the number of subscribed users and their profiles can grow very large, the scalability of the service is critical to the success of pub-sub systems.  ...  ACKNOWLEDGMENTS We would like to thank Yanlei Diao and her colleagues for providing the YFilter code for our experiments.  ...

Highly personalized information delivery to mobile clients

Bahattin Ozen, Ozgur Kilic, Mehmet Altinel, Asuman Dogac
2001 Proceedings of the 2nd ACM international workshop on Data engineering for wireless and mobile access - MobiDe '01  
Since the queries will be executed on the documents fetched over the Internet, it is natural to expect the documents to be XML documents.  ...  A critical issue for such systems is scalability, that is, the performance of the system should be in acceptable limits when the number of users increases dramatically.  ...  First phase of profile creation is resource selection. Users select the resource XML documents, stored in the repository, on which they want their queries to be executed.  ...

Securing XML-Based Multimedia Content [chapter]

Ernesto Damiani, Sabrina Capitani di Vimercati
2003 Security and Privacy in the Age of Uncertainty  
Also, the pervasiveness of XML as a data interchange format. has given rise to a number of standard formats for lIlultimedia, such as Sl\HL for multimedia presentations, SVG for vector graphics, VoiceXML  ...  Access control policies' syntax and enforcement is illustrated by applying the model to some of XML-based multimedia data formats for multimedia.  ...  For instance, XPath expression user _profile/ / [. / / group [@value = C Se-curityOfficer '] returns elements useLprof ile selected within profiles of users who belong to group Securi tyOfficer.  ...

Towards an Internet-Scale XML Dissemination Service [chapter]

Yanlei Diao, Shariq Rizvi, Michael J. Frnaklin
2004 Proceedings 2004 VLDB Conference  
On the other hand, the recent work on selective dissemination of XML data has made significant progress in moving from XML filtering to the richer functionality of transformation for result customization  ...  Publish/subscribe systems have demonstrated the ability to scale to large numbers of users and high data rates when providing content-based data dissemination services on the Internet.  ...  In the context of XML-based data dissemination, user profiles can involve constraints over both the structure and value of XML fragments, resulting in potentially more precise filtering of XML messages  ...

Access Control of SVG Documents [chapter]

E. Damiani, S. De Capitani di Vimercati, E. Fernández-Medina, P. Samarati
2003 IFIP Advances in Information and Communication Technology  
In this paper we exploit the XML-based data model of SVG to present a model and a syntax aimed at selectively controlling access to graphic infonnation on the Internet.  ...  The monolithic nature of traditional raster images makes controlled dissemination of their internal features a difficult task.  ...  Our approach allows to selectively transform SVG graphical data according to the user's profile, releasing only the features that the user is entitled to see.  ...
