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 triplestores, each publicly available through both SPARQL endpoints and resolvable URIs. To realise(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)
There has been lately an increased activity of publishing structured data in RDF due to the activity of the Linked Data community. The presence on the Web of such a huge information cloud, ranging from academic to geographic to gene related information, poses a great challenge when it comes to reconcile heterogeneous schemas adopted by data publishers. For(More)
The Linked Data initiative has given rise to an increasing number of RDF datasets, many of which are freely accessible online. These resources often arise as a result of database exports; however sufficient consideration may not be given to the unseen implications caused when they are used in the wider context of the Semantic Web. This paper investigates(More)
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)
RKB Explorer is a Semantic Web application that is able to present unified views of a significant number of heterogeneous data sources regarding a given domain. We have developed an underlying information infrastructure which is mediated by ontologies and consists of many independent triplestores. Our current dataset totals many tens of millions of triples,(More)
Detection of intracellular antigens by flow cytometry requires effective fixation and permeabilization of the cell membrane. This study compares three fixation/permeabilization techniques: two commercial chemical reagents, the ORTHOPermeaFix (OPF) and the FIX&PERM Cell Permeabilization Kit (F&P), and a novel method based on microwave heating (MWH). They(More)
Linked Data has provided the means for a large number of considerable knowledge resources to be published and interlinked utilising Semantic Web technologies. However it remains difficult to make use of this ‘Web of Data’ fully, due to its inherently distributed and often inconsistent nature. In this paper we introduce core challenges faced when consuming(More)
