Hi Richard,
I am familiar with the semantics of owl:equivalentProperty, just
unsure about its usage (more clearly, I do not know exactly how to add
a DBpedia mapping that uses that property, particularly for the case
where the namespace of the object is not defined on the DBpedia
ontology server). I do not know if namespaces are hardcoded (written
in Scala) inside the DEF (DBpedia Extraction Framework), or if there
is a way to define them on the wiki (mappings.dbpedia.org
<http://mappings.dbpedia.org>).
I hope the reduction of jargon per sentence makes the message clearer. :)
This helps a great deal. Would it be possible and advisable (i.e., not
too complicated) for my group to set up DEF locally and run it over
current Wikipedia? I see instructions for Ubuntu 10
(http://wiki.dbpedia.org/ExtractionOnUbuntu?v=fnb) and think that (so
long as things work on Ubuntu 12) it might be the most efficient way to
get an updated DrugBox data extraction that uses the new mappings.
Perhaps the DEF code could be grepd to find if and where namespaces are
defined in DEF. If it is feasible and advisable, would anyone on this
list know how to limit the extraction to just Drug pages?
kind regards,
-Rich
