sparql endpoint

[Soheila Dehghanzadeh]

Hi All,

I run this query last week at http://sparql.sindice.com/ and get 5000 results:

PREFIX an: <http://vocab.sindice.net/analytics#>
PREFIX any23: <http://vocab.sindice.net/dataset#>
SELECT DISTINCT ?node
WHERE {
    ?node any23:domain_uri ?domain .
    ?node an:source ?edge.
}
and now when i run it again, i get no result :-/
Does anyone know what is the problem ?

Hi Soheila D

We are currently reloading the analytics graph to have the fresh data
about all datasets
I will let you know when the process is done
Then your query should work fine again

Sorry for inconvenience
Szymon

Hi Soheila D

The analytics graph was reloaded
but I think your initial query war slightly wrong
I rewrote it a little

PREFIX an: <http://vocab.sindice.net/analytics#>
PREFIX any23: <http://vocab.sindice.net/>

SELECT ?node
FROM <http://sindice.com/analytics>
WHERE {
?node any23:domain_uri ?Source_domain .
?edge an:source ?node
}
LIMIT 10

1) the any23 namespace was wrong
2) the distinct is no needed as nodes in analytics graph are unique
3) it is good practice to put the limit at the end

Hope this helps

Cheers
Szymon

Hi Szydan,
thanks for correction but I run ur query and the 3 first nodes are the same :-/

[Soheila Dehghanzadeh]

and the other 7 are also the same :-/

[Soheila Dehghanzadeh]

and when i add the DISTINCT keyword i get the different nodes :-/

[Stéphane Campinas]

Hi Soheila,

you get the same nodes because you are querying for the edges, and one node possibly has multiple edges: the node foaf:Person has several properties, e.g., name, age, .... Therefore, you will have mutiple rows with that same node name.

Look at this query

PREFIX an: <http://vocab.sindice.net/analytics#>
PREFIX any23: <http://vocab.sindice.net/>

SELECT  ?node ?predicate ?target

FROM <http://sindice.com/analytics>
WHERE {
    ?node any23:domain_uri ?Source_domain .

    ?edge an:source ?node .
    ?edge an:label ?predicate .
    ?edge an:target ?target
}
LIMIT 10
