  In this work we consider anomalous and linear holographic hard wall (HW)
models for light unflavored mesons inspired by the AdS/CFT correspondence. The
anomalous dimensions depend on the logarithm of the spin $S$ of the meson state
and come from a semiclassical analysis of gauge/string duality. The anomalous
HW model produces very good masses and good Regge trajectories for mesons
compared with PDG data. Inspired by this anomalous HW model we also propose a
phenomenological modification of the dimension of the boundary operators such
that the model produces asymptotic linear Regge trajectories.
