Dear Alisha, You can use a consistency-preserving translation method from Goedel ALC ontology into its corresponding crisp ontology. The translation method can be done programmatically and then you do the crisp reasoning using Jena. The method is provided here: http://lat.inf.tu-dresden.de/teaching/ws2011-2012/FDL/FDL.pdf on page 15. Please be aware that there are some typos on the provided file.
