Fragmentation corrections to the triple hadronic-energy correlations in high-energy e-e+ annihilation are studied by a Monte Carlo calculation using various fragmentation models. Dependences on the infrared-cutoff parameters are studied and the infrared-insensitive regions are determined. The rates of decreases of the fragmentation corrections to triple correlations with increasing energy and to the standard energy-energy correlation asymmetry are compared. In particular, fragmentation corrections at energies near the Z0 peak are calculated. It is demonstrated that a statistically reasonable determination of the triple hadronic-energy correlation from the already available experimental data is feasible and could serve as an independent way of determining s.
