The aim of this paper is to initiate and investigate new soft sets over semihypergroups, named special soft sets and transitive soft sets and denoted by S_{H} and  T_{H}, respectively. It is shown that T_{H}=S_{H} if and only if \beta=\beta^{*}. We also introduce the derived semihypergroup from a special soft set and study some properties of this class of semihypergroups.
