Let $G$ be a simple reductive group over the complex numbers. Let $W$ be the Weyl group of $G$. We propose a description of the Springer representations of $W$ associated to various unipotent classes of $G$ by a purely algebraic method involving the families of various reflection subgroups of $W$ and which is suitable to computer calculations.
