  We present a quantitative assessment of the impact a future Electron-Ion
Collider would have in the determination of parton distribution functions in
the proton and parton-to-hadron fragmentation functions through semi-inclusive
deep-inelastic electron-proton scattering data. Specifically, we estimate the
kinematic configurations for which the forthcoming data are expected to have
the most significant impact in the precision of these distributions, computing
the respective correlation and sensitivity coefficients. Implementing the
reweighting technique over sets of simulated data with realistic uncertainties
for two different center-of-mass energies, we analyse the resulting upgraded
sets of PDFs and FFs, which have significantly reduced uncertainties.
