The well-known result of E. C. Posner state that a prime ring, if the commutator of each element and its image under a nonzero derivation is central, then the ring is commutative. This result has played a fundamental role in the development of the theory of centralizing mappings on noncommutative rings. Our purpose of this paper is to show this result and its generalizations to symmetric bi-semiderivation in rings without imposing any conditions on the ring, only containing a semiprime ideal. Specifically, we investigate rings that contain a semiprime ideal and prove that centralizing or commuting conditions imposed on symmetric bi-semiderivations force strong structural constraints.
