Hey Everyone, thanks so much for working on this awesome project! I just got started with Stanbol and find it very promising for some entity recognition tasks at hand.
Here's one issue that you might be able to help me with: I set up an EntityHub Linking Engine to detect entities defined in a custom vocabulary, as described at https://stanbol.apache.org/docs/trunk/components/enhancer/engines/entityhublinking. But in the enhancer list chain I added it to, the enhancer always shows as "currently not available". [image: Inline images 3] Even in DEBUG mode, this seems to be the only relevant entry in the logs: *INFO* [Thread-857] org.apache.stanbol.enhancer.jobmanager.event.impl. EnhancementJobHandler Error Message: Enhancement Chain failed because of required Engine 'testEntityExtraction' failed with Message: Unable to process ContentItem '<urn:content-item-sha1- 5b9e4c679944c06ed3bb3fe042e01839aa51c050>' with Enhancement Engine 'testEntityExtraction' because the engine is currently not active! A little bit more background: Because I could not get the EntityHub Linking Engine to run, I set up a (deprecated) Keyword Linking Engine instead, pointing to the same Referenced Site - a Managed Site holding my custom vocabulary. This works: I uploaded entities and they are correctly recognised by the enhancer chain. So, I'm rather sure the Managed Site / Solr index with the vocabulary are set up correctly. The configurations of the two engines are almost identical... just that the Keyword Linking Engine is active, and the EntityHub Linking Engine is not. Here's a screenshot of the latter: [image: Inline images 5] Any idea how to further debug this problem? Thanks, Manuel
