A new similarity measure between vague sets based on information similarity coefficient and its application

According to the facts that similar measure between vague set is based on the distance measure mostly, A new similarity measure between vague sets based on information similarity coefficient is presented,which can satisfy the axiom definition of similarity measure between vague sets. Finally,an application in the field of content-based recommendation system of electric commerce is given. The example shows that the methods is practical and effective and can improve the quality and accuracy of the recommendation.
