摘要: 根据Vague集距离及投影的概念,提出了一种新的相似度量方法,结合二维图形说明投影越大、距离越小,Vague集之间的相似度就越大,接着证明了该方法满足相似度量的约束条件,最后通过与已有方法的比较说明该方法的有效性。

Abstract: A new similarity measure method is given based on the concept of projectivity and distance of Vague sets.Then,combined with the two-dimensional graphics,it illustrates that the larger the projectivity and the shorter the distance,the larger the similarity measure.Later,it proves that the method satisfies all the restrict conditions.Finally,it shows that the method is effective by comparing with the existing methods.

Key words: Vague sets, similarity measure, projectivity, distance
