We introduce the notion of views as a mechanism for securing and providing access control in the context of XML. Research in XML has explored several efficient querying mechanism...
Kennaway proved the remarkable result that every (almost) orthogonal term rewriting system admits a computable sequential normalizing reduction strategy. In this paper we present ...
Abstract. Access control for semi-structured data is nontrivial, as witnessed by the number of access control approaches in recent literature. Recently a case has been made for exp...
Techniques for efficiently evaluating future time Linear Temporal Logic (abbreviated LTL) formulae on finite execution traces are presented. While the standard models of LTL are i...
The Web has been rapidly “deepened” by myriad searchable databases online, where data are hidden behind query forms. Helping users query alternative “deep Web” sources in ...
