hi all,
Hi there,
(version number?)
I don't see anything wrong in what your doing.
Presumably you've tried
PREFIX basekb: <http://rdf.basekb.com/>
SELECT * {
?s basekb:ns.mid ?object .
}
and
PREFIX basekb: <http://rdf.basekb.com/>
SELECT * {
?s basekb:ns.mid ?o .
FILTER (str(?o), "medic")
}
The other possibility is that the initial load was interrupted, a second
JVM accessed the database at some cocurent time or a use of database was
non transaction during an update (Fuseki is transactional).
I have loaded a part of basekbpro data into TDB by tdbloader command.
The size of the TDB store is about 26GB.
Number of triples or quads?
Then I use Jena fuseki server to publish the TDB store through a SPARQL
endpoint.
But when I run the following SPARQLs:
PREFIX basekb: <http://rdf.basekb.com/>
CONSTRUCT {?s ?p ?o .}
WHERE
{
?s basekb:ns.mid "/medicine/medical_trial_type/medical_trials" .
?s ?p ?o .
}
or
PREFIX basekb: <http://rdf.basekb.com/>
CONSTRUCT {?s ?p ?o .}
WHERE
{
?s basekb:ns.mid ?object .
FILTER regex(?object, "/medicine/medical_trial_type/medical_trials")
?s ?p ?o .
}
There is no any output. When I run the following SPARQL:
PREFIX basekb: <http://rdf.basekb.com/ns/>
CONSTRUCT {basekb:m.0dbzfg8 ?p ?o .}
WHERE
{
basekb:m.0dbzfg8 ?p ?o .
}
I can get the following output:

I have do another test. I have loaded m.0dbyyxn and m.0dbzfg8 related
triples into another TDB store by tdbloader command and then perform the
above SPARQLs, I can always get right output.
So I think whether the index of the first TDB load(26GB) has problems.
But I am not sure.
Any help or suggestions would be greatly appreciated.
Than you very much.
