Hi Dimitris, hi all,
Ive been quite busy the last few months, so now that Ive finally found
some spare time, Im taking another shot at DBpedia extraction for the
Serbian language.
Im making some progress with the latest version of the extraction
framework (I was pretty much stuck at the beginning with the previous
one). Ive successfully downloaded the latest Wikipedia dump, but Im
having problems extracting any triples from it. Heres what I have in my
extraction config file (comments removed for clarity):
-------------------------------------------------------------
base-dir=/home/uros/dbpedia/dumps
source=srwiki/20131009/srwiki-20131009-pages-articles.xml.bz2
languages=sr
extractors.sr=LabelExtractor
ontology=../ontology.xml
mappings=../mappings
uri-policy.uri=uri:en; generic:en; xml-safe-predicates:*
uri-policy.iri=generic:en; xml-safe-predicates:*
format.nt.gz=n-triples;uri-policy.uri
format.nq.gz=n-quads;uri-policy.uri
format.ttl.gz=turtle-triples;uri-policy.iri
format.tql.gz=turtle-quads;uri-policy.iri
--------------------------------------------------------------
The extraction framework is located in
/home/uros/dbpedia/extraction-framework.
The dump is inside /home/uros/dbpedia/dumps/srwiki/20131009.
As for the 'source' parameter, Ive tried including both the absolute path
and the one relative to the base-dir (but also leaving it out completely),
and Ive tried with and without the srwiki-yyyymmdd and sr: prefix, but
all to no avail. Also, Im trying a single extractor for starters, hoping
Ill get at least something (Ill fine tune it later).
When I run the extraction script with the above config file, I get the
following:

No changes in the target extraction dir, though. Any help would be much
appreciated!
