    "abstract": "We study the possibility to constrain the hidden strangeness content of the\nnucleon by means of the polarization observables in phi meson\nelectroproduction. We consider the OZI evading direct knockout mechanism that\narises from the non-vanishing s\\bar{s} sea quark admixture of the nucleon as\nwell as the background of the dominant diffractive and the one-boson-exchange\nprocesses. Large sensitivity on the nucleon strangeness are found in several\nbeam-target and beam-recoil double polarization observables. The small \\sqrt{s}\nand W region, which is accesible at some of the current high-energy electron\nfacilities, is found to be the optimal energy region for extracting out the OZI\nevasion process.",
