We investigate the potential impact of forthcoming Jefferson Lab
semi-inclusive polarized deep inelastic scattering proton measurements in the
determination of the sea quark polarization in the nucleon by means of a next
to leading order global QCD analysis. Specifically, we estimate the resulting
improvement in the constraints on polarized parton densities for the different
flavors, which is found to be significant for up and strange quarks, and the
correlation between remaining uncertainty ranges for each of the parton
species.Comment: 7 pages, 4 figures. Version to be published in the European Physical
