Abstract: Similarity measure plays an important role in the applications of Vague sets. The aim of this paper is to point out the drawbacks of similarity measure in literatures [16-17]. The restriction conditions of a similarity measure between Vague sets are proposed by introducing a weight factor. Finally, its availability is proved by an example in pattern recognition.
