I'm assuming you are asking about ATerm's and Pellet KnowledgeBase 
class. The class expressions are created through various functions 
provided in the utils.ATermUtils class. For example, a someValuesFrom 
restriction is created with makeSomeValues function. The properties (as 
all other named entities) are created with the makeTermAppl(String name) 
function. Then you add a restriction by calling KnowledBase.addSubClass 
function where subclass is the class you want to add restrictions to and 
the super class is the restriction.
