Hello,

I am planning to train topic models to recognize text content and find
the most related skos:Concept from DBpedia.
However most of the time the dbpedia nodes for categories /
skos:Concept are less informative than the resource assiocated with
the main article of the afore mentionned category in wikipedia.

Let's take an example, the category "History" is available as a
skos:Concept in dbpedia as:

-  http://dbpedia.org/resource/Category:History

It matches the following category page in wikipedia:

  - http://en.wikipedia.org/wiki/Category:History

On that page you can see the text:

The main article for this category is History.

Which is a link to the following wikipedia page:

  - http://en.wikipedia.org/wiki/History

Which has the following RDF resource in DBpedia:

  - http://dbpedia.org/resource/History

However the relationship:

http://dbpedia.org/resource/History [is the main resource for concept]
http://dbpedia.org/resource/Category:History

is not directly available in the DBpedia graph.

So my questions are:

1- Is it safe to assume that for any
http://dbpedia.org/page/Category:XXX skos:Concept I can find more data
in the matching http://dbpedia.org/resource/XXX resource?

2- Is there a plan to make that relationship more explicit?

Regards,
