  We calculate the polarization of Lambda and Anti-Lambda particles produced in
deep inelastic polarized lepton scattering. We use two models: the naive quark
model and a model in which SU(3)$_F$ symmetry is used to deduce the spin
structure of SU(3) octet hyperons from that of the proton. We perform the
calculations for Lambda and Anti-Lambda produced directly or as decay products
of $\Sigma^0$ and $\Sigma^*$.
