Hi,
there is no magic in that.
It only happens that wikipedia has got a page Isere (
http://en.wikipedia.org/wiki/Isere) which is actually a mere redirect to
Isère (http://en.wikipedia.org/wiki/Is%C3%A8re).
Hence the framework links the two DBpedia entities together in a triple
- dbpedia:Isere dbpedia-owl:wikiPageRedirects dbpedia:Isère
-
- However, I think this is not always true for all the pages which
contain non-ASCII chars, that is wikipedia is not filled with redirects
from ASCII folded pages.
-
- This is why in my opinion you should enrich the data with additional
triples which link ASCII folded and other languages labels to the original
entity, e.g.
- dbpedia:Italy rdfs:label "Italy"@en
- dbpedia:Italy rdfs:label "Italia"@it
- and
- dbpedia:Isère rdfs:label "Isère"@en
- dbpedia:Isère rdfs:label "Isere"@en
-
- (this is just an example, I would not use rdfs:label for the ASCII
folded label but another property).
-
- Hope this helps.
-
- Cheers
- Andrea
