使用sparql查询在dbpedia中查找特定人员

Question

So I'm learning SPARQL and trying to get a specific person out of dbpedia using a SPARQL query. I'm using their endpoint at https://dbpedia.org/sparql to do this query. The person I'm trying to find is Albert Einstein . I found on his page that he has a property of dbp:name. So I wrote a query to find Albert Einstein by his name:

select ?person where {?person <http://dbpedia.org/property/name> "Albert Einstein"} LIMIT 100

Unfortunately, this gives me just an empty result set (I think) as i'm justing seeing an empty table with the header of 'Person'

What's going wrong?

Answer 1

I'm not sure why your query doesn't work, but this one does:

select ?person where {?person foaf:name "Albert Einstein"@en} LIMIT 100

Though this returns all entities named "Albert Einstein", which includes the scientist, but also an album of the same name. If you want just people, you can use:

select ?person
where {
  ?person foaf:name "Albert Einstein"@en.
  ?person a foaf:Person.
}
LIMIT 100
