@AKSW Would you put an illustration in an Answer? I think I understand your advice, but would like to see your Answer so I too can test it. — Jay Gray, Jun 01 '16 at 12:58
@JayGray Instead of `?saket dbo:wikiPageID 57570.` do something like `?saket dbo:wikiPageID ?wikiPageId . filter (57570 <= ?wikiPageId && ?wikiPageId <= 57670)`. — Joshua Taylor, Jun 01 '16 at 13:18
