Consuming RDF ontologies as dictionaries

[Spico Florin]

Hello!
  I'm newbie in UIMA. I would like to know if it is possible to create a
dictionary (vocabulary) from a RDF triplestore. I would like that UIMA to
be used to classify a words contained in a text by using a given ontology
stored in a triplestore.
How can I use UIMA in this particular use case?
  I look forward for your answers.
  Thank you.
  Regards,
  Florin
