We introduce a method for learning query transformations that improves the ability to retrieve answers to questions from an information retrieval system. During the training stage...
Scientific data in the life sciences is distributed over various independent multi-format databases and is constantly expanding. We discuss a scenario where a life science research...
Networks of sensors are used in many different fields, from industrial applications to surveillance applications. A common feature of these applications is the necessity of a mo...
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...
Abstract. Membership queries are basic predicate operations that apply to datasets. Quantifications of such queries express global properties between datasets, including subset inc...
