Jaccard index

It is not very different in form from the Jaccard index but has some different properties.

The Jaccard index is defined by the following formula:

He developed the Jaccard index of similarity (he called it coefficient de communauté) and published it in 1901.

As was chosen uniformly at random, and define an LSH scheme for the Jaccard index.

The overlap coefficient is a similarity measure related to the Jaccard index that computes the overlap between two sets which is defined as follows:

Suppose is composed of subsets of some ground set of enumerable items and the similarity function of interest is the Jaccard index .

Report the results comprehensively - Along with the mapping, at least distance measure (e.g., Sorenson index, Jaccard index) and reliability (e.g., stress value) should be given.

It is a commonly used indicator of the similarity between two sets: two sets are more similar when their Jaccard index is closer to 1, and more dissimilar when their Jaccard index is closer to 0.
