Processing ontology alignments with SPARQL
(IEEE, 2008)
Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which the data must be translated from one ...
Entailment for Domain-restricted RDF
(Springer, 2008)
We introduce domain-restricted RDF (dRDF) which allows to associate an RDF graph with a fixed, finite domain that interpretations for it may range over. We show that dRDF is a real extension of RDF and discuss impacts on ...
Scalable Authoritative OWL Reasoning on a Billion Triples
(2008)
In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
inContext: A Pervasive and Collaborative Working Environment for Emerging Team Forms
(2008)
Participants in current team collaborations belong to different organizations, work on multiple objectives at the same time, and frequently change locations. They use different devices and infrastructures in collaboration ...
Processing ontology alignments with SPARQL

Previewing Semantic Web Pipes
(Springer, 2008)
In this demo we present a first implementation of Semantic Web Pipes, a powerful tool to build RDF-based mashups. Semantic Web pipes are defined in XML and when executed they fetch RDF graphs on the Web, operate on them, ...
SAOR: Authoritative Reasoning for the Web
(Springer, 2008)
In this paper we discuss the challenges of performing reasoning on large scale RDF datasets from the Web. We discuss issues and practical solutions relating to reasoning over web data using a rule-based approach to ...
XSPARQL: Traveling between the XML and RDF worlds - and avoiding the XSLT pilgrimage
(Springer, 2008)
With currently available tools and languages, translating between an existing XML format and RDF is a tedious and error-prone task. The importance of this problem is acknowledged by the W3C GRDDL working group who faces ...
