Bio2RDF 1 - Drugbank: a source of drugs and drug targets.
2 - SIDER: a source of drug indications and drug effects.
3 - OMIM: a source of diseases and disease genes.
4 - ChEBI: an ontology for chemicals
5 - DO: an ontology of diseases

Methods
The RDF data were generated using the open source scripts from the Bio2RDF project [1]. In particular, we used the Release 3 candidate scripts from the latest development in Michel Dumontier's github repo [2]. The resulting files were loaded into a pre-compiled Virtuoso 7.1.0 [3]. We used the bulk RDF loader [4] to load these files into their specified graphs. We updated the facet browser by initializing the tables and updating the index [5]. The server is available via its facet interface [6] and sparql endpoint [7].

BioGateway The shortage of attractive interfaces, for end users (e.g. physicians), to exploit LOD is leaving much of those efforts shaded out. In order to overcome such a problem, the QA community and the LOD community should combine efforts to close the aforementioned gap. Ideally, we expect to come up with an interface in which users could write down questions (in natural language, see examples below) which in turn will be sent a knowledge base (e.g. federated) and return a correct answer. Disclaimer: This is not a comprehensive list of resources but a list used within the OKBQA hackathon in 2014. The list below provides a set of LOD resources within the Bio-community: List of NL questions for those LOD resources:
