RKB Explorer is a Semantic Web application that is able to present unified views of a significant number of heterogeneous data sources. We have developed an underlying information infrastructure which is mediated by ontologies and consists of many independent triple-stores, each publicly available through both SPARQL endpoints and re-solvable URIs.

The Semantic Web vision involves the production and use of large amounts of RDF data. There have been recent initiatives amongst the Semantic Web community, in particular the Linking Open Data activity and our own ReSIST project, to publish large amounts of RDF that are both interlinked and dereferenceable. The proliferation of such data gives rise to(More)
The Web of Data is growing at an ever increasing rate, with RDF datasets being produced in the order of billions of triples. The effect of this increase has meant that many entities for which knowledge is being published have developed a number of URI synonyms. Managing URI synonymity plays an important part in establishing a solid foundation for data(More)
Facilitating knowledge acquisition is a task that usually requires special purpose interfaces with which users are not familiar. Providing effective acquisition through a familiar interface, such as a wiki, can provide a route to acquiring knowledge for low user investment. We present an architecture that is being used in the ReSIST project based on a(More)
Much of the Semantic Web relies upon open and unhindered interoperability between diverse systems; the successful convergence of multiple ontologies and referencing schemes is key. However, this is hampered by the difficult problem of coreference, which is the occurrence of multiple or inconsistent identifiers for a single resource. This paper investigates(More)
The move towards a semantic web has been in progress for many years and more recently there have been applications that make use of semantic web technology. One of the features that made the Web so easy to use is the ability to search web pages in a matter of seconds through the use of search en­ gines. Now that the use of OWL and RDF as a knowledge(More)
