Abstract A single-valued neutrosophic multi-set is characterized by a sequence of truth membership degrees, indeterminacy degrees and falsity degrees. Nature allows us to consider multiple information in the truth, memberships which pretty useful multi-criteria group decision making. In this paper, we sequences intuitionistic fuzzy values instead numbers define concept fuzzy-valued multi-set. m...

Measuring similarity between two strings is a fundamental step in text classification and other problems of information retrieval. Recently, kernel-based methods have been proposed for this task; since kernels are inner products in a feature space, they naturally induce similarity measures. Information theoretic (dis)similarities have also been the subject of recent research. This paper describ...

Generalized trapezoidal fuzzy numbers (GTFNs) have been widely applied in uncertain decision-making problems. The similarity between GTFNs plays an important part in solving such problems, while there are some limitations in existing similarity measure methods. Thus, based on the cosine similarity, a novel similarity measure of GTFNs is developed which is combined with the concepts of geometric...
