What is "bisimulation invariance of ALC "?
Prove the theorem of "bisimulation invariance of ALC "?
Prove that no ALUE-concept description is equivalent to (<=3R).
Consider the role composition construct ( 0 ) whose semantics is defined as follows :
(R@S)^(J)={((x,y)|EEz),((x,z)inR^(J)):} and {:(z,y)inS^(J)}, with R,S role names.
Do the language ALC simulate the construct o?
