Hi,
It seems like important dbpedia ontology properties, such as starring,
director, budget etc (generated from the mapping of en Infobox : Film)
are not always present for several english films, although the
corresponding wikipedia pages do have these properties and are using
the Infobox : Film template.
For example, consider the following english wikipedia page (which is
using the Infobox : Film template)
http://en.wikipedia.org/wiki/Blade_Runner
<http://en.wikipedia.org/wiki/Blade_runner>
The dbpedia ntriples for the above page does not have the
<http://dbpedia.org/ontology/starring> properties
http://dbpedia.org/data/Blade_Runner.ntriples
This wikipedia page for Blade Runner is also one of the test pages at
the following url -
http://mappings.dbpedia.org/server/mappings/en/extractionSamples/Mapping_en:Infobox_film.
The test results generated on this page also do not have the
<http://dbpedia.org/ontology/starring> properties for this film.
The starring property is indeed present in the Infobox on the
wikipedia page for this film (http://en.wikipedia.org/wiki/Blade_Runner).
However, the same dbpedia ontology property for starring does get
extracted for some other films such as "Army of Darkness"
I saw several cases of the above behavior of dbpedia ontology
properties (starring, director, musicComposer, budget etc) missing for
some films, while being present for some other films. However, in each
case where the properties were missing in the dbpedia data set, the
same properties were present on the corresponding wikipedia page.
Is there a reason why the dbpedia ontology properties do not seem to
be getting extracted for some films, while the same properties are
getting extracted for some other films?
Please have a look on that thread [1].
Thanks
Arun
