Jaccard Similarity using N-grams instead of words (1-gram) is called w-shingling. Though Jaccard Similarity and w-shingling are simple methods for measuring text similarity, they perform pretty decently in practice, as shown in the results section at the end of this post!
Jaccard Similarity is frequently used in data science applications. Example use cases for Jaccard Similarity: Text mining:find the similarity between two text documents using the number of terms used in both documents E-Commerce:from a market database of thousands of customers and millions of items...

However, statistical hypothesis testing using this similarity coefficient has been seldom used or studied. Results We introduce a hypothesis test for similarity for biological presence-absence data, using the Jaccard/Tanimoto coefficient. Several key improvements are presented including unbiased estimation of...

Jaccard Index (similarity metric) calculation in 'Power Query' 08-16-2021 03:42 PM hi all, I have a dataset consisting of a table with 33 columns x 30 rows. The values in each cell are text and I want to calculate the so-called Jaccard Index, a measure of similarity, fo...
Thus, it would be useful to have a similarity measure based not only on PWMs but also on threshold values. The similarity measure for two PWMs, taking into account their thresholds, was first introduced in MoSta [13], which computes the correlation between the numbers of hits of two PWMs...
The values in each cell are text and I want to calculate the so-called Jaccard Index, a measure of similarity, for each combination of two columns. I can do this manually in Power Query but for a table with 33 columns this results in 528 comparisons so I'm hoping this coul...
