strange identifiers in

Are there any guidelines for the construction of identifiers in

The reason that I ask is that there are some rather strange identifers, or at 
least some rather strange uses of identifiers.

Consider, for example, the identifier Abdomen (  
One might think that this refers to a part of the bodies of some animals.   
However, Abdomen is instead an instance of PhysicalExam, along with 
Appearance, CardiovascularExam, Eye, Neuro, and VitalSign.

It seems to me that this is very bad design, particularly if 
identifiers are supposed to be used by people who might not have a background 
in the representation of knowledge.
