Many of the widely used binary similarity measures, such as the Jaccard index and the Forbes coefficient (also known as fold change), were initially developed in the context of species presence/absence problems within ecology [5, 6]. Within ecology, there has been a long debate on the properties of different similarity measures [7, 8]. Similarity coefficients specific for dichotomic (binary) variables, ... the related values of Jaccard’s similarity are always smaller than those of the Sorensen- Dice similarity and the simple matching coefficient. In contrast, values of the Sorensen- Dice similarity may be greater or smaller than the related values of the Simple matching coefficient depending on whether the number of ... Correcting a similarity index for chance agreement requires computing its expectation under fixed marginal totals of a matching counts matrix. For some indices, such as Jaccard, Rogers and Tanimoto, Sokal and Sneath, and Gower and Legendre the expectations cannot be easily found. We show how such similarity indices can be expressed as functions of other indices and expectations found by ... You're right. It's not common practice for evaluation, although Jaccard does have some nice properties that F1 (= Dice) does not, such as being the complement of a true distance metric. And in whatever context, @bthirion had assumed jaccard_similarity_score would work on binary problems, since many people first know this index for set comparison. x: Depending on the context: A data frame of binary predictors..

The similarity and dissimilarity (per simple transformation) coefficients proposed by the calculations from the binary data are as follows: Dice coefficient (also known as the Sorensen coefficient), Jaccard coefficient, Kulczinski coefficient, Pearson Phi, Ochiai ... Numerous binary similarity measures and distance measures have been proposed in various fields. For example, the Jaccard similarity measure was used for clustering ecological species [20], and Forbes proposed a coefficient for clustering ecologically related species [13, 14].
