Hi Luigi, Regarding extracting the text from XML files you might want to check if the TikaEngine can be used for that.
Note also that you can parse pre-existing annotations to the Stanbol Enhancer. You might want to have a look at this example [1]. Sorry I have not understood the part with "<entity_1> <owl:sameAs> <entity_2>" best Rupert [1] http://stanbol.apache.org/docs/trunk/components/enhancer/enhancerrest#example-4-parse-existing-free-text-annotations On Tue, Jun 11, 2013 at 4:27 PM, Luigi Selmi <luigise...@gmail.com> wrote: > Hi Rupert, > > thanks for your answers.
