Hi Francesco,
I think an information it's missing here: what are you trying to do
concretely? "Using Solr as semantic search engine" means at the same
time everything and nothing :) and (I guess) it involves something more
than a thesaurus.
Keeping things simple, and assuming your only concern is the thesaurus,
what is your search requirement / scenario / expectation? I mean, let's
assume you can index / manage the thesaurus hierarchy, something like
BT
---> T
------> NT1
------> NT2
------> NT3
What do you want to do with such data?
When the user search T you want a query expansion to T,BT?
Or you want to store that information at index time?
Or you want to reduce all T to BT?
What about the narrower terms? How do you imagine their role within the
search context?
In any case, there's nothing (AFAIK) in Solr that understands SKOS /
RDF. In the links you posted it seems someone already went in that
direction but I don't know those add-ons and (see above) I don't know
your needs.
Ciao,
Andrea

Hi Andrea,
Thanks very much for your helpful link!
Is there a way to contact Hoss?
About that link, I have two doubts:
-) I'm using Solr (5.4.1) in schemaless mode, and I can't manage the
schema.xml in order to customize the SynonymFilterFactory;
-) If I copy my thesaurus in the synonyms.txt file, I lose all the hierarchy
terms;
According to your experience, these two plugins can be helpful for my
purpose?
