I am sorry, but I have to disagree: this is easily possible in OWL  
itself: simple retrieve all instances of ONCOGENEs: any DL reasoner  
(eg Pellet) will retrieve exactly all instances of oncogene, whether  
they have been declared as such or whether they are genes that are  
associated with a disease of type cancer....
