Sorry, but this is not possible. The stanbol enhancer will always include the Resource that defines the label and this is the Alias. As a workaround you could use the Entityhub to query for the Class of the returned Alias. Based on the provided excerpt of your Ontology parsing this JSON FieldQuery to the query service of the Entityhub (http://localhost:8080/entityhub/query) should provide the Class for the Alias. { "constraints": [{ "type": "reference", "field": "http://www.lornet.org/acm-ccs/proton#hasMainAlias";, "value": "http://www.lornet.org/acm-ccs/proton#Alias_794fe2e1-441b-4565-bb0e-4d6f0cabed1f";, }] } best Rupert > Best, > Srecko Joksimovic > On Mon, Aug 15, 2011 at 8:18 PM, Srecko Joksimovic > <[email protected]> wrote: >> >> Hi, >> I will have to try this, as soon as possible, but I am sure it will be >> alright. >> >> Thank you very much! >> >> Best, >> Srecko Joksimovic >> >> -----Original Message----- >> From: Rupert Westenthaler [mailto:[email protected]] >> Sent: Monday, August 15, 2011 16:43 >> To: srecko joksimovic; [email protected] >> Subject: Re: Apache Stanbol >> >> On Mon, Aug 15, 2011 at 3:06 PM, srecko joksimovic >> <[email protected]> wrote: >> > That was the problem!
