NETWORK FREQUENCY AND COSINE SIMILARITY MEASURE

AbstractThe Pythagorean fuzzy set is extended from intuitionistic fuzzy set. Pythagorean fuzzy sets arecharacterized by the three degrees such that membership, non-membership, and hesitancy which satisfies the condition that the sum of the squares of its membership degree, and non-membership degree is equal to or less than one. It reaches many application with the support of score, Accuracy, Distance, and Similarity measures. In this paper, the Pythagorean fuzzy set isexplained with the help of cosine similarity and distance-based similarity. An illustrativeexample is also included and a comparative study is made with the Score, Accuracy, andSimilarity measure function.
