Hi,
I would like to ask if there is any way to query dbpedia (using SPARQL) in order to find out all the entities that are links to other wiki-articles within the wiki-article of a specific entity whose URI is known.

For example I know the resource URI of the entity :"President of the United States" : http://dbpedia.org/resource/President_of_the_United_States.

in the corresponding wiki-article some of the first links to other articles are : P.O.T.U.S. (Sirius XM) <http://en.wikipedia.org/wiki/P.O.T.U.S._%28Sirius_XM%29>., head of state <http://en.wikipedia.org/wiki/Head_of_state>, head of government <http://en.wikipedia.org/wiki/Head_of_government> , United States <http://en.wikipedia.org/wiki/United_States>. etc.

Is there any way to get the above mentioned entities in any form (eg URI) ?

Something like:
http://dbpedia.org/resource/P.O.T.U.S.
http://dbpedia.org/resource/Head_of_state
etc.

Is relevant information about links and backlinks stored in triplet form?

You can find the information you are looking for in the DBpedia dump titled "Wikipedia Pagelinks" which is available for download at [1].


Thank you!!
Chryssa
