我正在尝试以下SPARQL查询:
SELECT ?uri ?label
WHERE {
?uri rdfs:label "Weblex"@en .
?uri rdfs:label ?label
}
但是,我收到一条神秘的错误消息:
ERROR: SPARQL-QUERY: queryStr=SELECT ?uri ?label
WHERE {
?uri rdfs:label "Weblex"@en .
?uri rdfs:label ?label
}
java.util.concurrent.ExecutionException:
java.util.concurrent.ExecutionException: java.lang.RuntimeException:
java.util.concurrent.ExecutionException:
java.lang.IllegalArgumentException: Unable to read data:
com.bigdata.rwstore.PhysicalAddressResolutionException: Address did not resolve to physical address: -118579
at java.util.concurrent.FutureTask.report(FutureTask.java:122)
查询看起来像是有效的,所以我在做什么错了?
