Input -> PTS is a component of a product for cleaning mowers.
Inference -> PTS is a product for gardening (i defined this in a  
hierarchical ontology, superclass).

These classes are too specific for Dbpedia (maybe bad example?) and  
you can imagine what difficult would be to government documents (with  
its particular idiosyncrasy).

I want that Stanbol "forgets" another source. I need that, in the  
plain text, Apache Stanbol choose tags only defined in my ontology.


I have a PTS but i don't have garden.



Apache Stanbol don't extract "garden" because it isn't defined like an  
entity (class) in my owl file or my own ontology.
