We describe our method for benchmarking Semantic Web knowledge base systems with
respect to use in large OWL applications. We present the Lehigh University Benchmark …

Recently, the SPARQL query language for RDF has reached the W3C recommendation
status. In response to this emerging standard, the database community is currently exploring …

We study fundamental aspects related to the efficient processing of the SPARQL query
language for RDF, proposed by the W3C to encode machine-readable information in the …

In this paper we present FedBench, a comprehensive benchmark suite for testing and
analyzing the performance of federated query processing strategies on semantic data. The …

In the cultural heritage domain information systems are increasingly deployed, digital
representations of physical objects are produced in immense numbers and there is a strong …

In this paper, we present an evaluation of four knowledge base systems (KBS) with respect
to use in large OWL applications. To our knowledge, no experiment has been done with the …

Semantic Web languages are being used to represent, encode and exchange semantic data
in many contexts beyond the Web–in databases, multiagent systems, mobile computing, and …

We survey nearly 1300 OWL ontologies and RDFS schemas. The collection of statistical
data allows us to perform analysis and report some trends. Though most of the documents …

In this paper we benchmark three popular database representations of RDF/S schemata and
data:(a) a schema-aware (ie, one table per RDF/S class or property) with explicit (ISA) or …

The tutorial first addresses requirements and semantic problems to integrate digital
information into large scale, meaningful networks of knowledge that support not only access …
