Hi Rupert and all,

With logging I managed to get the SPARQL query which resulted in error.
On the Marmotta ui this specific query gives an unknown exception while
evaluating SPARQL query

The SPARQL generated from Stanbol Sesame yard is as below;

SELECT DISTINCT ?id ?v_4 ?v_2 ?v_3
WHERE {
  {
    SELECT ?id
    WHERE {
      ?id <http://www.w3.org/2000/01/rdf-schema#label> ?v_3
        FILTER((regex(str(?v_3),"\\bCMP\\b","i") ||
regex(str(?v_3),"\\bProducts\\b","i")) && ((lang(?v_3) = "") || (lang(?v_3)
= "en"))) .
    }
    LIMIT 12
          }
  OPTIONAL { ?id <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> ?v_2 . }
  OPTIONAL { ?id <
http://stanbol.apache.org/ontology/entityhub/entityhub#entityRank> ?v_4 . }
  OPTIONAL { ?id <http://www.w3.org/2000/01/rdf-schema#label> ?v_3 . }
}

I would also like to know your opinion in using Sesame Yard with Marmotta
kiwi for entity linking.
I'm trying this to horizontally scale Stanbol instances with a single
entityhub(the Sesame yard + Marmotta kiwi)


Thanks,
Dileepa
