Hi,
I have been trying to run Stanbol and it is throwing some exception at some
engine. I have attached a screenshot and a exception is below. I just need
to know if it is because of some problem from my side as it was fine
yesterday. Please do let me know if it is working for you all.
org.apache.stanbol.enhancer.servicesapi.ChainException: Enhancement
Chain failed because of required Engine 'dbpediaLinking' failed with
Message: Unable to process ContentItem
'<urn:content-item-sha1-65bff53b1bad98467308a5dcbe7fec3690430a79>'
with Enhancement Engine 'dbpediaLinking' because the engine was unable
to process the content (Engine class:
org.apache.stanbol.enhancer.engines.entitytagging.impl.NamedEntityTaggingEngine)(Reason:
Unable to initialize the Cache with Yard dbpediaIndex! This is usually
caused by Errors while reading the Cache Configuration from the
Yard.)!
