"WebLSH is used to perform Nearest Neighbor Searches based on a simple concept of "similarity". We say two items are similar if the intersection of their sets is sufficiently large. This is the exact same notion of Jaccard Similarity of Sets. Recall the picture above of similarity. Our final measure of similarity, 1/5, is Jaccard Similarity. " - Lsh image similarity
