Jaccard's coefficient focuses on the similarity between finite sample sets, calculating the size of the intersection divided by the size of the union of the sample sets. It does not consider matching zero entries (i.e., cases where both sets lack an element), which is a key difference from the matching coefficient that counts both matching presence and absence of features.
