Similarity in soft set theory

We introduce and study the concept of similarity between soft sets, which is an extension of the equality for soft set theory. We also introduce the concepts of conjunction parameter (α∧β)(α∧β) and disjunction parameter (α∨β)(α∨β) of ordered pair parameter 〈α,β〉〈α,β〉 for soft set theory, and we investigate modified operations of soft set theory in terms of ordered parameters.
