It has been a long standing puzzle how to establish the connection between the chiral solitonpicture of the baryon, which essentially views baryons as mesonic lumps, and the quark parton model, which regards baryons as composites of almost non-interacting, point-like quarks. While the former has been quite successful in describing static properties of the nucleon, the latter, being firmly established within the context of deep inelastic scattering (DIS), has been quite successful in predicting the spin average DIS *Supported in part by the Deutsche Forschungsgemeinscha (DFG) under contract Re 856/2-2 and by funds provided by the US Department of Energy (DOE) under cooperative agreement # DE-FC02-94ER4081 8.

N2 - Nucleon structure functions are studied within the chiral soliton approach to the bosonized Nambu-Jona-Lasinio model. The valence quark approximation is employed which is justified for moderate constituent quark masses (∼ 400 MeV) as the contribution of the valence quark level dominates the predictions of nucleon properties. As examples the unpolarized structure functions for the νp and ν̄p scattering and the structure functions entering the Gottfried sum rule are discussed. For the latter the model prediction is found to reasonably well agree with a corresponding low-scale parametrization of the empirical data.
