Extended jaccard coefficient example
WebTanimoto Coefficient Tanimoto coefficient, also known as extended Jaccard coefficient ( Tanimoto, 1957) is used for handling the similarity of document data in text mining. In the case of binary attributes, it reduces to the Jaccard coefficient. Tanimoto coefficient between vectors p,q is defined by equation (3): (,)=. ‖‖+‖‖ . (3) WebThe Jaccard / Tanimoto coefficient is one of the metrics used to compare the similarity and diversity of sample sets. It uses the ratio of the intersecting set to the union set as the …

A similar statistic, the Jaccard distance, is a measure of how dissimilar two sets are. It is the complement of the Jaccard index and can be found by subtracting the Jaccard Index from 100%. For the above example, the Jaccard distance is 1 – 33.33% = 66.67%.
