Query: Chiral Soliton Models and Nucleon Structure Functions   We outline and review the computations of polarized and unpolarized nucleon
structure functions within the bosonized Nambu-Jona-Lasinio chiral soliton
model. We focus on a consistent regularization prescription for the Dirac sea
contribution and present numerical results from that formulation. We also
reflect on previous calculations on quark distributions in chiral quark soliton
models and attempt to put them into perspective.
