    1. Referenced by Graphs: shows how many times the URI is found as subject in the relevant graph(s):

      SPARQL
      SELECT ?g count (*)
      where
        {
          graph ?g { <URI> ?p ?o }
        }
      group by ?g
      order by desc 2
      limit 20

    2. Source Graphs: shows how many times the URI is found as object in the relevant graph(s):

      SPARQL
      SELECT ?g count (*)
      where
        {
          graph ?g { ?s ?p <URI>  }
        }
      group by ?g
      order by desc 2
      limit 20

    3. Direct co-references: shows results as subject and calculated rank, based on running transitive closure over owl:sameAs of the URI in subject or object:

      SPARQL
      SELECT ?syn ( sql:rnk_scale (<LONG::IRI_RANK> (?syn)))
      where
        {
          { SELECT ?s ?syn
            where
             {
               {?syn owl:sameAs ?s } union {?s owl:sameAs ?syn}
             }
          }
          option (transitive, t_distinct, t_min (0), T_in (?s), t_out (?syn)) . filter (!isliteral (?syn) &amp;&amp; ?s = <URI> )
        }
      order by desc 2
      limit 20

    4. Indirect co-references: shows expanded results for objects concur with the URI by IFP:

      SPARQL
      SELECT distinct ?syn ?p ?o (sql:rnk_scale (<LONG::IRI_RANK> (?syn)))
      where
        { <URI> ?p ?o .  filter (0 != (<LONG::bif:rdf_is_sub> ("b3sifp", ?p, lod:ifp_like, 3))) .
          ?syn ?p ?o .
      }
      order by desc 4
      limit 20
