Hello Christopher,
A similar error was reported for other query by dy developer of
different application and the bug has been fixed. The fix should appear
quite soon in Virtuoso Open Source release and in dbpedia.org and
related installations.

Hello Matt,
Aggregating by grouped expression is formally senseless and should
signal an error, The problem is that the error is not signaled, the
error diagnostics should be improved. The compiler go crazy and result
from one grouping is used for all groups.
This works:
SELECT
?label ?uri
Hello,
The output of
select distinct * where {
?city a http://dbpedia.org/ontology/City .
?city http://dbpedia.org/property/capital ?capital } limit 100
on dbpedia.org demonstrates some problem, probably with data extraction.

Try the new software tools for yourself. Speed
for graphs so it will better support this
particular case without losing the speed in worst case.

http://dbpedia.org/sparql?default-graph-uri=query=select+*+where+%7B+%3Fs+a+%3Fo+%7D
in such a
way that it seems that the graph keyword is a part of the object. So the
actual search is for graph keyword for http://dbpedia.org; AND
person, this does not matter if almost all data are in one graph but
helps in other cases.

Is there a way
from some graph if it is known
WHERE
{ ?s a ?t . FILTER ( ?s IN (resource1, resource2,
resource3 ...)) }
A single triple pattern with IN operator would be much cheaper.

Anyway the original query is wrong, esp. if many resources have more than one
type or if at least one resource has no type at all.
