We analyze the semileptonic weak decays of the octet baryons in a "model independent" approach, based on the algebraic structure of the Chiral Quark-Soliton Model. We argue that this analysis is in fact more general than the model itself. While the symmetry breaking for the semileptonic decays themselves is not strong, other quantities like Δs and ΔΣ are much more affected. We calculate ΔΣ and Δq for all octet baryons. Unfortunately, large experimental errors of Ξ- decays propagate in our analysis, in particular, in the case of ΔΣ and Δs. Only if the errors for these decays are reduced, the accurate theoretical predictions for ΔΣ and Δs will be possible.
