Invalid DBpedia URI in dataset v1.6

[emilio....@gmail.com]

Dear chairs,

We have still found some invalid DBpedia URIs contained in the latest version of the dataset (1.6). These are the tweet_ids:

94960661582450690
91753088574164992
96229136179281920

and the corresponding DBpedia URIs are:

http://dbpedia.org/resource/Demonstration_(protest)
http://dbpedia.org/resource/Les_Brown_(speaker)
http://dbpedia.org/resource/Rolls-Royce_Group_PLC

Hi all,

The last one is a valid DBpedia. But I confirm that the first and second ones are not DBpedia URIs.

I can see that those URIs can be found at live.dbpedia.org, see for instance http://live.dbpedia.org/page/Demonstration_(protest)

@chairs: Do we have to rely on live DBpedia ?

Dear Emilio and Ugo,

Thanks for spotting these problems.
We can confirm that http://dbpedia.org/resource/Demonstration_(protest) and http://dbpedia.org/resource/Les_Brown_(speaker) are indeed not correct DBpedia URIs.
We are performing some consistency checks right now and should be sending an updated version later today.

Regarding dbpedia live, we have validated the entity URIs using http://dbpedia.org/sparql that corresponds to the DBpedia v3.9 snapshot.
Our URI validation script performs the following SPARQL ("PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> SELECT ?label  WHERE {  <http://dbpedia.org/resource/Rolls-Royce_Group_PLC> rdfs:label ?label. }")

Hope it helps.
Best regards,
