Thanks for your suggestions.
I do not know whether attachments are allowed, so I paste the
extraction.properties below. (apparantly I already tried adding the full
path:dbpedia.extraction.mappings.DisambiguationExtractor,
but without, the same error message follows).
extractors.nl<http://extractors.nl>=MappingExtractor,DisambiguationExtractor
and
extractors.nl<http://extractors.nl>=MappingExtractor,org.dbpedia.extraction.mappings.DisambiguationExtractor,HomepageExtractor
give the same error.
If I only have
extractors.nl<http://extractors.nl>=MappingExtractor
the extraction process takes about 30 minutes and seems to end without problems
(I haven't looked at generated outputfiles yet though).
(I started without commenting out the other extractors, but then despite having
languages=nl, other languages were being textracted)
Kind regards,
Lourens

Can you show us your extraction.properties? I suspect you forgot the line below?
languages=nl
I am also not sure if you should have fully qualified
(org.dbpedia.extraction.mappings.DisambiguationExtractor) or just the class
name (DisambiguationExtractor).
Cheers,

I am trying to set up dbpedia-spotlight for the Dutch language. There are some
datasets available for Dutch (nl),
but I expect to at least need the dbpedia "disambiguation" dataset, which is
not available for download.
After setting up extraction_framework for "nl" and doing :
editing extraction.properties: reoving all extractors.** except:
extractors.nl<http://extractors.nl/>=MappingExtractor,org.dbpedia.extraction.mappings.DisambiguationExtractor,HomepageExtractor,ImageExtractor,\
InterLanguageLinksExtractor)
$ cd dump;mvn scala:run

I assume this means that some classes have not been implemented for "nl"?
If so, I would like to know if such an effort is on the way or whether it would
be feasible for me to give it a try?
Is there some pointer/documentation on how to get started?
Thanks,
Lourens
==================
DETAILS OF WHAT I DID
I managed to install the extraction_framework. The documentation seems a bit
out of date though so it could be I
did things wrong.
I managed to download the "nl" wikipedia input by editing dump.properties and
doing
$ cd dump; mvn scala:run -Dlauncher=download
Extraction started when commenting out all
other "extraction.**=" entries in dump/extraction.properties leaving only
extractors.nl<http://extractors.nl/>=MappingExtractor
and running
$ mvn scala:run
The output indicates that extraction proceeds nicely.
But I expect that in the result the "disambiguation" result will be missing.
When I replace extractors.nl<http://extractors.nl/> (analoguous to other
languages):
extractors.nl<http://extractors.nl/>=MappingExtractor,org.dbpedia.extraction.mappings.DisambiguationExtractor,HomepageExtractor,ImageExtractor,\
InterLanguageLinksExtractor
I get error messages mentioned above.
