The conversion of SIDER to aTags is now available, see

A small excerpt of the aTags:
http://hcls.deri.org/atag/data/SIDER_atags_excerpt.html
The aTags re-use URIs from DBpedia, OBO disease ontology and OBO
symptom ontology. Most statements link a DBpedia URI (a drug) to an
OBO URI (a disease/symptom).
As a simple example, the following query shows statements in SIDER
that deal with some kind of CNS disease:
SELECT ?atag_content ?some_cns_disease
WHERE {
?atag sioc:content ?atag_content .
?atag sioc:topic ?some_cns_disease .
?some_cns_disease rdfs:subClassOf disease_ontology:DOID_331 .
}
LIMIT 500
Results: http://tinyurl.com/SIDER-about-CNS
Some of the results look funny, for example, Memantine has
'Alzheimer's' listed as a side-effect. However, Memantine is actually
used as a treatment for Alzheimer's. I have to look into that -- maybe
SIDER should just be seen as providing associations between drugs and
diseases/symptoms, without specifying whether they cause or cure the
disease? This is also the case with the TCM datasets that Jun
converted to RDF recently.
Note that the SPARQL endpoint currently only contains a part of the
data, possibly the Virtuoso Sponger has problems with parsing large
RDFa files. Also note that others also have recently converted SIDER
into RDF as well (Anja Jentsch, Peter Ansell).

Matthias,
We'll take a look at what's happening with the RDFa cartridge. This
should be a none issue re. using the Virtuoso Crawler + RDFa Sponger
Cartridge to put the extracted triples in a designated Named Graph.
