Solution
Jaccard’s coefficient is different from the matching coefficient in that the former does not count matching zero entries while the latter does.
Jaccard's coefficient, also known as the Jaccard similarity index, only considers the presence of attributes, i.e., it only counts the matching ones and ignores the matching zeros. On the other hand, the matching coefficient counts both matching ones and zeros. This makes the Jaccard coefficient more suitable for sparse data sets where zeros might not necessarily indicate similarity.
