  We prove local well-posedness for the initial-boundary value problem (IBVP)
associated to the Schr\"odinger-Korteweg de Vries system on right and left
half-lines. The results are obtained in the low regularity setting by using two
analytic families of boundary forcing operators, being one of these family
developed by Holmer to study the IBVP associated to the Korteweg-de Vries
equation (Communications in Partial Differential Equations, 31 (2006)) and the
other family one was recently introduced by Cavalcante (Differential and
Integral Equations (2017)) in the context of nonlinear Schr\"odinger with
quadratic nonlinearities.
