This work introduces a new query inference model that can access data and communicate with a teacher by asking finitely many boolean queries in a language L. In this model the pa...
We demonstrate a system for querying probabilistic XML documents with simple XPath queries. A user chooses between a variety of query answering techniques, both exact and approxim...
We examine the power of incremental evaluation systems that use an SQL-like language for maintaining recursively-de ned views. We show that recursive queries such as transitive clo...
XQForms is the first generator of Web-based query forms and reports for XML data. XQForms takes as input (i) XML Schemas that model the data to be queried and presented, (ii) decl...
