Akdag and Ozkan pointed out in [1, Example 1] that the collection of soft sets is a soft topology over the universe where is the set of parameters. This conclusion is not correct since , , , , , , , and many of soft sets belong to the familyand their soft intersection and soft union do not exist in . Consequently, [1, Examples 27, 28, 29, 30] also are incorrect. Example  3.3 in [2] already proved the results in [1, Remark 12] and [2, Examples 4.3 and 4.4] also proved the results in [1, Remark 26].
