DERI Health Care and Life Science Knowledge Base

NOTE: THIS KB HAS BEEN DEPRECATED. THE INFORMATION HERE IS FOR HISTORIC PURPOSES. You can access the NEW HCLS KB at http://hcls.deri.org:8080/openrdf-sesame/repositories/hclskb We are no longer keeping this datasets updated but provided a catalogue of all linked life sciences dataset, described using the Vocabulary for Interlinked Dataset (VoiD) at http://hcls.deri.org/RoadMapEvaluation/ and queriable as a SPARQL endpoint at http://hcls.deri.org:8080/openrdf-sesame/repositories/roadmap

The knowledge base can be accessed through a SPARQL endpoint: http://hcls.deri.org/sparql The contents of the knowledge base can also be explored through a faceted searching / browsing interface: http://srvgal14.deri.ie:8081/fct/

The HCLS Knowledge Base at DERI is a Virtuoso-based triplestore containing information relevant to life science, medicine and health care. It contains RDF/OWL data that was generated by current and previous participants of the W3C Semantic Web for Health Care and Life Science Interest Group. A major part of the HCLS Knowledge Base is comprised of a mirror of the Neurocommons Knowledge Base maintained by Science Commons.

The HCLS Knowledge Base contains over 400 million RDF statements.

If you have suggestions for relevant RDF/OWL data that should be added to the KB, please propose them to the mailing list public-semweb-lifesci@w3.org (requires prior registration).

How to query named graphs contained in the knowledge base

The HCLS Knowledge Base is divided into subsections (named graphs) which are listed below. To query a graph such as `http://hcls.deri.org/resource/graph/drugbank` you can use a SPARQL query such as

 
SELECT * 
FROM <http://hcls.deri.org/resource/graph/drugbank> 
WHERE {?s ?p ?o} 
LIMIT 20

or, alternatively:

SELECT * 
WHERE {
  GRAPH <http://hcls.deri.org/resource/graph/drugbank> 
    {?s ?p ?o} 
}
LIMIT 20

The latter syntax allows you to direct subqueries to different graphs, for example:

PREFIX owl: <http://www.w3.org/2002/07/owl#>
PREFIX go: <http://purl.org/obo/owl/GO#>
PREFIX obo: <http://www.geneontology.org/formats/oboInOwl#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>

select  *
where {
  graph <http://purl.org/science/graph/inferred-relations> {
    ?class rdfs:subClassOf go:GO_0008150
  }
  graph <http://purl.org/science/graph/obo/GO> {
    ?class rdfs:label ?name.
    ?class obo:hasDefinition ?def.
    ?def rdfs:label ?definition .
  }
  filter(regex(str(?name),"[Dd]endrite"))
}

Note that clicking on the URIs of the named graphs will not necessarily lead you anywhere. They are just used inside the triplestore as names for graphs, and might not resolve via HTTP.

Please try to keep the server load of your queries low. This can easily be accomplished by 1) restricting you queries to the named graphs you need, instead of querying the entire triplestore or a multitude of graphs, 2) uinge the LIMIT clause in your queries.

DBpedia

A subset of DBpedia is contained within the HCLS Knowledge Base. This subset contains the english labels and short abstracts of all DBpedia entries, as well as the YAGO hierarchy. The rationale for including a subset of DBpedia is that it provides a huge taxonomy of entities that are relevant for the HCLS domain (among many other things).
