Just to say that use of Thesaurus for geographic concepts is very valuable 
in context of local government and community projects where a particular 
geographical location can have many alternative names and spellings.

AW: [Dbpedia-discussion] Using DBpedia resources as skos:Concepts?
Sent by:

Hi Richard,
In my eyes, it's completely  ok to use skos:exactMatch or skos:closeMatch 
in a situation like this (I did it  myself for the STW Thesaurus for 
Economics mapping to dbpedia).
Thesauri and classifications  are not restricted to abstract concepts. 
Some thesauri deal explicitly with  individual things, e.g. the widely 
used Getty "Thesaurus of Geographic Names" or  "Union List of Artist 
Names". Other thesauri (like STW) have sections (or  facets, as Leonard 
put it) on geografic names along with others containing  "pure" concepts. 
SKOS, as I understand it, is intended to cover all this and to  be used 
beyond strict class hierarchies or class/individual  dichotomies.
By the way, some of the SKOS  properties (especially the 
prefLabel/altLabel/hiddenLabel semantics) can be  useful in a broad range 
of applications. Eg. dbpedia itself could be used as a  great source for 
synonym candidates by mapping the resources to skos:Concept and  the 
labels for dbpedia:redirect resources to skos:altLabel. 
Cheers,  Joachim

Betreff: [Dbpedia-discussion] Using DBpedia resources as  skos:Concepts?


I want to get some broader feedback and opinion on  this question.

There is a use case where an external dataset is modelled  in SKOS, and 
we want to map it to DBpedia. Something  like:

      a skos:Concept;
     owl:sameAs <http://dbpedia.org/resource/Michelle_Obama>;

I've used owl:sameAs here. Now the problem is that my:433256 is  a 
skos:Concept, while dbp:Michelle_Obama is a foaf:Person. I  wonder 
wether that's a problem. I can't see any immediate  contradiction 
arising from that, but I'm uncertain.

Another  option would be to use skos:closeMatch or skos:exactMatch, but 
these  are intended for use between skos:Concepts, while I'm trying to 
connect  a skos:Concept to a foaf:Person.

The main question, I guess, is wether  people in the DBpedia project 
would consider the  assertion

     <http://dbpedia.org/resource/Michelle_Obama>  a skos:Concept .

to be acceptable or erroneous, or wether SKOS folks tell  me that 
skos:Concept is obviously disjoint from foaf:Person.

I  know that this is a complex issue, so I'm not really looking for  a 
"right" or "wrong" answer. I'm more interested in getting all the  pros 
and cons and pitfalls and caveats on the table, so please, if you  have 
any opinion on the issue, I want to hear it.

I'm cc'ing Pat  Hayes, because he said he's interested in that kind  of 

All the best and thanks for your  time,
