We report a beyond mean-field calculation of mass current and superfluidityfraction for a system of few bosons confined in a ring geometry in the presenceof a rotating weak link induced by a potential barrier. We apply theMulticonfiguration Hartree Method for bosons to compute the ground state of thesystem and show the average superfluidity fraction for a wide range ofinteraction strength and barrier height, highlighting the behavior of densitycorrelation functions. The decrease of superfluidity fraction due to theincrease of barrier height is found whereas the condensation fraction dependsexclusively on the interaction strength, showing the independence of bothphenomena.
