 Entity Matching Model (EMM) solves the problem of matching company names between two possibly very
 large datasets. EMM can match millions against millions of names with a distributed approach.
 It uses the well-established candidate selection techniques in string matching,

 These so-called indexers act complementary for selecting realistic name-pair candidates.
 On top of the indexers, EMM has a classifier with optimized string-based, rank-based, and legal-entity
