And just in case you haven't found it, a load of these hard-won equivalences

Caveat emptor, some of these hard won equivalences will be hard
losses. The sameAs assertions are incorrect. They equate a description
of the values of an independent variable in a clinical study to one of
the drugs administered in the intervention, the drug Ramelteon.
"Subjects demonstrating low sleep efficiencies and prolonged sleep
latencies, will be randomly assigned to continue to receive SHI
accompanied by either placebo or Ramelteon (8 mg). Matching placebo
will be obtained and the medication pre-packaged and ordered based on
the randomization results"
Thanks for pointing this out. I agree that for this case, sameAs is an
incorrect type for the links to other drug sources since intervention
is not necessarily a drug, and has a description associated with it.
We should treat drug as an entity for the sameAs links to make more
sense. I'm working on this and will let you all know once I update the
data source.
Oktie,
All of us that are consuming the Linked Open Drug Data (LODD) really
need to be notified. I am a little shocked that this anomaly (as
identified by Alan) exists re. use of "owl:sameAs" in the current data
set release.

It is not straightforward to figure this out, either - there is no
obvious backlink that leads you back from
http://data.linkedct.org/resource/intervention/51572 to the source of
the information http://clinicaltrials.gov/ct2/show/NCT00576927
where the quote used as the value of linkedct:description is found.
I will look into this as well. There might be a problem with the
version of the data source I've used, although the HTML pages have the
association between the intervention and the trial now.
Thanks,
Oktie
While a person browsing this will be able to disambiguate, if you
depend on these equivalences for any sort of reasoning you will land
up dubious conclusions.

Hi all,
I am attempting to merge 3 databases: (i) Clinicaltrials.gov <http://clinicaltrials.gov/>
, (ii) Geonames <http://www.geonames.org/> , (iii) FDA
<http://www.fda.gov/Drugs/InformationOnDrugs/ucm135162.htm> based on ontologies.
There are RDF Triples already defined for (i) http://linkedct.org/index.html and there is
already an ontology present for (ii) http://www.geonames.org/ontology/ . However, there
is no ontology present for the FDA database. The field "Zip Code" is common
for all the three databases.
If the FDA datasets are not published as RDF yet, we can certainly take the
lead in publishing them as a part of the Linking Open Drug Data [1] project.
[1] http://esw.w3.org/topic/HCLSIG/LODD
LinkedCT already provides links to Geonames, but please let me know if you see
any missing links.
Regards,
Oktie
Could anyone suggest possibilities of how to merge the three databases, based
on ontologies?
Thanks,
