Let X be an initial universal set, P(X) the power set of X, and A a set of parameters. A pair (F,A), where F is a map from A to P(X), is called a soft set over X . A soft set (F,A) of a soft topological space (X,?,A) is said to be soft ?-open if (F,A)? ?cl(int(cl(F,A))). Then some related properties and characterizations of soft ? -open sets have been discussed. By using the notion of soft ? -open sets several classes of functions called soft ?-continuous, almost soft ?-continuous, weakly soft ? -continuous, contra soft ?-continuous and almost contra soft ? -continuous are studied. Also, several properties of these functions were studied and investigated
