I'm having trouble contructing a basic query which selects a string so 
that it prefers one language, over others but always tries to return 

So I have names

:item schema:name "name"@en
:item schema:name "nimi"@fi
:item schema:name "namn"

I need query that returns the English name ("name"@en) , but if not 
found the name without language ("namn"), and as last resort name in 
Finnish ("nimi"@fi)

This query returns one random name:

(SAMPLE(?s_label_g) as ?s_label)
FROM <http://some_graph/>
     ?s a ?s_type .
     ?s <http://schema.org/name> ?s_label_g
GROUP BY ?s ?s_type

Anyone can help?
