Evidence conflict measurement method based on similarity coefficient and Jaccard matrix
Aiming at the open issue that the classical conflict coefficient and Jousselme distance measure can not correctly judge the conflict evidence,a new measurement of conflict was presented based on the definition of similarity coefficient and Jaccard matrix.By calculating the similarity coefficient between the evidence and the Jaccard coefficient matrix,the similarity coefficient is transformed into the conflict degree of the evidence.Theoretic proof and numreical examples verify the efficiency of the proposed measurement.A typical example is analyzed and compared with other methods.It has been shown by comparison with other methods that the proposed measurement is more accurate to measure evidence conflict.
