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
The dbpedia ntriples for the above page does not have the
<http://dbpedia.org/ontology/starring>
propertieshttp://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?
ThanksArun
