We address the problem of query rewriting for TSL, a language for querying semistructured data. We develop and present an algorithm that, given a semistructured query q and a set ...
Query optimization is a computationally intensive process, especially for complex queries. We present here a tool, called PLASTIC, that can be used by query optimizers to amortize...

The development of a distributed database systemrequires effective solutions to many complex and interrelated design problems. The cost dependenciesbetween query optimization and ...
— Finding the k nearest neighbors (kNN) of a query point, or a set of query points (kNN-Join) are fundamental problems in many application domains. Many previous efforts to solve...
An ontology is an explicit specification of shared conceptualization. The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies, a...
