Thanks Sergio and Dileepa for your responses We haven't been able to resolve the issue. We therefore decided to keep just one class and one instance value "University of Salzburg" in our custom ontology and try to extract this entity and also link it but we could not get this running. I am sure we are missing some configurations.
I am sharing a google drive folder at below link https://drive.google.com/folderview?id=0B-vX9idwHlRtRFFOR000ZnBBOWM&usp=sharing This folder has 3 files: 1) A word document which shows felix snapshots of what all configurations we did while configuring Yard, yardsite, entiy linking engine and weighted chain 2) our custom ontology 3) the result of SPARQL against our graphuri using SPARQL endpoint May i request you all to please look at these files and let us know if we are missing something in configurations. We have referred to below web links in order to configure stanbol for using our custom ontology for entity extraction and linking http://stanbol.apache.org/docs/trunk/customvocabulary.html http://stanbol.apache.org/docs/trunk/components/entityhub/managedsite http://stanbol.apache.org/docs/trunk/components/enhancer/engines/entityhublinking http://stanbol.apache.org/docs/trunk/components/enhancer/chains/weightedchain.html Thanks in advance for your valuable help.
