All data on inclusive and semi-inclusive spin asymmetries measured on nucleon targets were used. We present the results for the flavour dependence of polarized sea inside a nucleon. An excellent agreement between inclusive and semi-inclusive data on polarized structure functions was found in our model.12 pages, latex, 5 postscript figuresHigh Energy Physics - Phenomenologytext
