A system can only be called semiclassical if there are parts of the system that are described classically and parts decsribed quantum-mechanically. In this paradigm, physical quantites are described in a power series of ##\hbar##, with the zero order corresponding to classical physics and higher orders corresponding to quantum corrections.

Given the above, I do not see why the limit ##\hbar \rightarrow 0## called the semiclassical limit and not the classical limit. After all, in the limit that ##\hbar \rightarrow 0##, the system becomes classical and there are no quantum-mechanical corrections.
