The {\\tt AAK24} QCD analysis incorporates SU(2) and SU(3) symmetry breaking, specifically $\\delta \\bar{u} \\neq \\delta \\bar{d} \\neq \\delta \\bar{s}$, while assuming $\\delta \\bar{s}$ and $\\delta s$ are equal. Emphasizing the significance of the semi-inclusive data, the study explores the determination of polarized sea quark distributions.
