Two main parameters, which determine the radial velocity semi-amplitude of the host star in a star-planet system, are the planet mass and the orbital period. In order to examine the effect of planet mass on the radial velocity semi-amplitude, we firstly select sensitive data of spectroscopic orbital solutions of 737 systems, given in the database of exoplanet.org. The selected systems are then categorized into 31 groups according to their orbital periods. For each group, an empirical relation between the radial velocity semi amplitude and the planet mass is obtained. In order to check the accuracy of these empirical relations, the measured and expected values of planet masses are compared.
