Sources of data uncertainty and imprecision are numerous. A way to handle this uncertainty is to associate probabilistic annotations to data. Many such probabilistic database mode...
Keyword search has traditionally focussed on retrieving documents in ranked order, given simple keyword queries. Similarly, work on keyword queries on structured data has focussed...
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...
