Thanks for your answer but I still have problems.I actually need to built an application that will directly connect to the server of dbpedia without the need to download any dumps. But when I try to query dbpedia to get possible Wikipagelinks (that I have already check they exist in the dumps) I get no valid answers.For example the query: SELECT distinct ?Plinks WHERE { <http://dbpedia.org/resource/Anarchism> <http://dbpedia.org/ontology/wikiPageWikiLink> ?Plinks . } will return nothing, not even when I enter the query on theVirtuoso SPARQL Query Editor online.
This is because the dump titled "Wikipedia Pagelinks" is not loaded to the official endpoint. So, I would suggest you to establish your own endpoint, i.e. you can download all DBpedia dumps and load them onto one of your machines and direct your queries against it.

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!!
