A Prototype Knowledge Base for the Life Sciences(About) The prototype we describe is a biomedical knowledge base, constructed for a demonstration at Banff WWW2007 , that integrates 15 distinct data sources using currently available Semantic Web technologies such as the W3C standard Web Ontology Language [OWL] and Resource Description Framework [RDF]. This report outlines which resources were integrated, how the knowledge base was constructed using free and open source triple store technology, how it can be queried using the W3C Recommended RDF query language SPARQL [SPARQL], and what resources and inferences are involved in answering complex queries. While the utility of the knowledge base is illustrated by identifying a set of genes involved in Alzheimer's Disease, the approach described here can be applied to any use case that integrates data from multiple domains.
Managing URI Synonymity to Enable Consistent Reference on the Semantic Web(About) This paper sets out an architecture for managing URI equivalences on the Web of Data by using Consistent Reference Services.
The underlying philosophy of the CRS is to treat URIs as first-class entities and separate the
equivalences of a URI into a separate knowledge base that will be aware of both intra-
repository and inter-repository synonymity. Equivalent URIs are grouped into
bundles which are themselves given their own URI. When an application wishes to
find an equivalent URI, the CRS can be queried to retrieve the corresponding bundle.
