Thanks for the pointer; this is very cool! We would be happy to share

Hi,
I have to launch 2 million queries against a Wikidata instance.
I have loaded Wikidata in Virtuoso 7 (512 RAM, 32 cores, SSD disks with RAID 0).
The queries are simple, just 2 types.
select ?s ?p ?o {
?s ?p ?o.
filter (?s = ?param)
}
ata filtered by
sitelinks (perhaps also allowing other high-degree or high-PageRank
nodes to pass the filter). At least I know I would use such a dump.

Hey all,
Andra recently mentioned about finding laureates in Wikidata, and it

You agree with me that this query :

query, but throws an error in WDQS service [1].
It is a valid SPARQL query, but what you're essentially asking is to

This looks great Lydia, thanks!!
The descriptions look like enough for me to catch the idea and explain

If such a student is interested, we will let you know. :)

So at my university the undergraduate students must do a three-month

need to involve research but should result in a final demonstrable

Hi Stas,
I think in terms of the dump, /replacing/ the Turtle dump with the
N-Triples dump would be a good option. (Not sure if that's what you were
suggesting?)
As you already mentioned, N-Triples is easier to process with typical
unix command-line tools and scripts, etc. But also any (RDF
number of wiki subjects in all
languages).
I have no idea yet how to write the SQL/SPARQL for this, but rankable Q*
identifiers, new Q* identifiers and Google would be places I'd begin if
I did. What do you think?
Cheers, Scott

cking it for Wikidata was
the lack of load-balancing support in the open source version, not
the performance of a single instance.
