  The identification of problematic meson states as the members of the quark
model $q\bar{q}$ nonets by using a hadronic resonance spectrum is discussed.
The results favor the currently adopted $q\bar{q}$ assignments for the
axial-vector, tensor, and 1 $^3F_4$ $J^{PC}=4^{++}$ meson nonets, and suggest a
new $q\bar{q}$ assignment for the scalar meson nonet which favors the
interpretation of the $f_0(980)$ and $f_0(1710)$ mesons as non-$q\bar{q}$
objects. We also suggest that the 2 $^3S_1$ $\frac{1}{2}(1^{-})$ state should
be identified with the $K^\ast (1680)$ rather than $K^\ast (1410)$ meson.
