Hi Kata, Have you overwritten the old solr index in the datafiles folder or have you started from the scratch after fixing the encoding of the RDF files?
Just a hint: you can check if your entities have been indexed by querying then with the EntityHub API at Stanbol Web interface Hope that helps, Rafa On Mon, Jan 11, 2016 at 7:19 PM Lejtovicz, Katalin < katalin.lejtov...@oeaw.ac.at> wrote: > Dear All, > > I have some problem with using custom vocabularies to enhance my content. > I created an index with Stanbol from a vocabulary, deployed the .jar file > and copied the solr index file to the datafiles folder, and created an > EntityHub Linking Engine, plus a weighted chain, where the following > pipeline was configured: langdetect, opennlp-sentence, opennlp-token, > opennlp-pos, opennlp-chunker, and the an EntityHub Linking Engine for my > custom vocab. > > It worked fine, when text was pasted in this enhancement chain in the user > interface of Stanbol, entities were found.
