  First of all, we focused soft {\beta}-open sets and soft {\beta}-closed sets
over the soft topological space and investigated some properties of them.
Secondly, we defined the concepts soft {\beta}-continuity, soft
{\beta}-irresolute and soft {\beta}-homeomorphism on soft topological spaces.
We also obtained some characterizations of these mappings. Finally, we observed
that the collection S{\beta}r-h(X,{\tau},E) was a soft group.
