Query: Asymmetries from Semi-inclusive Polarized Deep Inelastic Scattering   The analysis of semi-inclusive data from deep inelastic scattering of
polarized muons off polarized protons and deuterons by the SMC is presented.
The resulting charged hadron asymmetries are used to determine polarized
valence and sea quark distributions and their contributions to the nucleon
spin. In addition, a new approach to derive inclusive asymmetries is discussed.
